+Installation Instructions

+without warranty of any kind.
+
+Basic Installation
+==================
+
+ Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package. The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package. Some packages provide this
+`INSTALL' file but do not implement all of the features documented
+below. The lack of an optional feature in a given package is not
+necessarily a bug. More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+ The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system.
+
+ Running `configure' might take a while. While running, it prints
+ some messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package, generally using the just-built uninstalled binaries.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation. When installing into a prefix owned by root, it is
+ recommended that the package be configured and built as a regular
+ user, and only the `make install' phase executed with root
+ privileges.
+
+ 5. Optionally, type `make installcheck' to repeat any self-tests, but
+ this time using the binaries in their final installed location.
+ This target does not install anything. Running this target as a
+ regular user, particularly if the prior `make install' required
+ root privileges, verifies that the installation completed
+ correctly.
+
+ 6. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+ 7. Often, you can also type `make uninstall' to remove the installed
+ files again. In practice, not all packages have tested that
+ uninstallation works correctly, even though it is required by the
+ GNU Coding Standards.
+
+ 8. Some packages, particularly those that use Automake, provide `make
+ distcheck', which can by used by developers to test that all other
+ targets like `make install' and `make uninstall' work correctly.
+ This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you can use GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'. This
+is known as a "VPATH" build.
+
+ With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory. After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+ On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor. Like
+this:
+
+ ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CPP="gcc -E" CXXCPP="g++ -E"
+
+ This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+ By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them. In general, the
+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+ The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+ The first method involves providing an override variable for each
+affected directory. For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'. Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated. The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+ The second method involves providing the `DESTDIR' variable. For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names. The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters. On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of `${prefix}'
+at `configure' time.
+
+Optional Features
+=================
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+ Some packages offer the ability to configure how verbose the
+execution of `make' will be. For these packages, running `./configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with `make V=1'; while running `./configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with `make V=0'.
+
+Particular systems
+==================
+
+ On HP-UX, the default C compiler is not ANSI C compatible. If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+ ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+ HP-UX `make' updates targets which have the same time stamps as
+their prerequisites, which makes it generally unusable when shipped
+generated files such as `configure' are involved. Use GNU `make'
+instead.
+
+ On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file. The option `-nodtk' can be used as
+a workaround. If GNU CC is not installed, it is therefore recommended
+to try
+
+ ./configure CC="cc"
+
+and if that doesn't work, try
+
+ ./configure CC="cc -nodtk"
+
+ On Solaris, don't put `/usr/ucb' early in your `PATH'. This
+directory contains several dysfunctional programs; working variants of
+these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
+in your `PATH', put it _after_ `/usr/bin'.
+
+ On Haiku, software installed for all users goes in `/boot/common',
+not `/usr/local'. It is recommended to use the following options:
+
+ ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on. Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS
+ KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+ Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug. Until the bug is fixed you can use this workaround:
+
+ CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+ Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+ Print a summary of the options unique to this package's
+ `configure', and exit. The `short' variant lists options used
+ only in the top level, while the `recursive' variant lists options
+ also present in any nested packages.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+ Use DIR as the installation prefix. *note Installation Names::
+ for more details, including other options available for fine-tuning
+ the installation locations.
+
+`--no-create'
+`-n'
+ Run the configure checks, but stop before creating any output
+ files.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+-*-Mode: outline-*-
+
+* News for v1.1:
+
+** coredump unwind support
+** New arch: SuperH
+** Improved support for PowerPC, ARM
+** Lots of cleanups, perf tweaks
+** pkg-config support
+
+* News for v1.0:
+
+** Fast unwind (rbp, rsp, rip only) on x86_64 with a fallback to
+ slow code path (Lassi Tuura)
+** Improved local and remote unwinding on ARM (Ken Werner)
+** Testing, stability and many fixes on x86 (Paul Pluzhnikov)
+** FreeBSD port and clean separation of OS specific bits
+ (Konstantin Belousov)
+** Thanks for all the bug reports, contributions and testing!
+
+* News for v0.99:
+
+** Greatly improved x86-64 support thanks to Arun Sharma.
+** Support for PPC64 added by Jose Flavio Aguilar Paulino.
+
+* News for v0.98.6:
+
+** Fix address-leak triggered by invalid byte-order. Fixed by Andreas Schwab.
+** On ia64, get_static_proc_name() no longer uses a weak reference to
+ _Uelf64_get_proc_name(), since that was causing problems with archive
+ libraries and no longer served any apparent purpose. Fixed by
+ Curt Wohlgemuth.
+
+* News for v0.98.5:
+
+** Fix a typo in the man-page of unw_create_addr_space().
+** Fix an off-by-1 bug in the handling of the dynamic ALIAS directive
+ for ia64. Reported by Todd L. Miller.
+** Fix a bug in libunwind-ptrace which could cause crash due to extraneous
+ munmap() calls.
+
+* News for v0.98.4:
+
+** Fix a typo in _ReadSLEB.c which caused hangs when throwing exceptions
+ from Intel ICC-compiled programs. Reported by Tommy Hoffner.
+
+* News for v0.98.3:
+
+** Make it possible to link against libunwind-ia64.a only (i.e., without
+ requiring libunwind.a as well). This keeps apps which need only
+ remote unwinding cleaner, since they logically have no dependency
+ on libunwind.a.
+** Dont link against libatomic_ops for now. Due to a packaging bug on
+ Debian, linking against this library causes libunwind.so to get
+ a dependency on libatomic_ops.so, which is not at all what we want.
+ Fortunately, we don't have to link against that library on x86 or
+ ia64 since the library is strictly needed only for platforms with
+ poor atomic operation support. Once the libatomic_ops package is fixed,
+ we can re-enable linking against libatomic_ops.
+
+* News for v0.98.2:
+
+** Fixed bug which caused _UPT_get_dyn_info_list_addr() to sometimes fail
+ needlessly. Found by Todd L. Miller.
+
+** When using GCC to build libunwind on ia64, libunwind.so had an
+ unresolved reference to __divdi3. This is undesirable since it
+ creates an implicit dependency on libgcc. This problem has been
+ fixed in the 0.98.2 release by explicitly linking against libgcc.a
+ when building libunwind.
+
+* News for v0.98.1:
+
+** Fixed a bug which caused "make install" to install libunwind-common.h.in
+ instead of libunwind-common.h.
+** Fixed a bug in the ia64 {sig,}longjmp() which showed on
+ SuSE Linux 9 because it's using a newer compiler & the EPC-based system
+ call stubs.
+** Fixed incorrect offsets in tests/ia64-test-nat-asm.S.
+ Warning: you'll need a GNU assembler dated later than 21-Sep-2004 to
+ get this file translated correctly. With an old assembler, "make check"
+ will get lots of failures when running Gia64-test-nat or Lia64-test-nat!
+** Convert tests/bt into a full-blown test-case. It's designed to
+ trigger a (rarely-encountered) bug in the GNU assembler on ia64.
+ The assembler has been fixed and once the libraries (libc etc)
+ have been rebuilt, this test will pass.
+** Added test-case tests/run-ptrace-misc which, on ia64, triggers a bug in
+ current GCC (including v3.4.2) which causes bad unwind info.
+
+* News for v0.98:
+
+** Update libunwind to be compliant with the updated/expanded
+ ia64 unwind specificiation by HJ Lu [1]. This is needed for
+ GCC 3.4 compatibility.
+
+ [1] http://www.kernel.org/pub/linux/devel/gcc/unwind/
+
+** Initial support for x86-64 has been added courtesy of Max Asbock.
+ Along with this came a bunch of DWARF2 unwinder fixes.
+
+** A new rountine unw_strerror() has been added courtesy of
+ Thomas Hallgren.
+
+** Including <libunwind.h> now defines 4 macros that can be used
+ to determine the version number of libunwind. Specifically,
+ UNW_VERSION_MAJOR, UNW_VERSION_MINOR, UNW_VERSION, and
+ UNW_VERSION_CODE are defined by the header now.
+
+** Bug fixes
+*** Fix a memory-leak in _UPT_get_dyn_info_list_addr() courtesy of Ed Connell.
+*** Fix a crash in libunwind-ptrace courtesy of Mark Young.
+*** Fix a bug in ia64-version of unw_init_remote() which prevented
+ it from working correctly for the local address space. Reported by
+ Troy Heber.
+*** Many other small and not so small fixes.
+
+* News for v0.97:
+
+** unw_get_proc_name() may now be called from signal-handler.
+
+** The ptrace-helper routines are now declared in libunwind-ptrace.h.
+ Applications which use ptrace-based unwinding should include
+ <libunwind-ptrace.h> to get the _UPT_*() routines declared.
+
+** libunwind has been split into a "local-only" and a "generic" versions.
+ The former is optimized for local unwinding (within a process) and
+ is called libunwind.so (shared version) or libunwind.a (archive
+ version). The generic version is not limited to unwinding within a
+ process and is called libunwind-generic.so (shared version)
+ libunwind-generic.a (archive version). Similarly, the ptrace()
+ support has been separated out into a convenience library called
+ libunwind-ptrace.a. For the most part, backwards-compatibility
+ is retained. However, when building an application which uses
+ libunwind, it may be necessary to change the linker command-line
+ as shown in the table below:
+
+ Application which does: Before v0.97: With v0.97:
+ ----------------------- ------------- -----------
+ local unwinding only: -lunwind -lunwind
+ remote unwinding: -lunwind -lunwind-generic
+ cross unwinding: -lunwind-PLAT -lunwind-PLAT
+ ptrace-based unwinding: -lunwind -lunwind-ptrace -lunwind-generic
+
+ The motivation for this splitting is to keep libunwind.so as minimal
+ as possible. This library will eventually be loaded by most (if not
+ all) executables and hence it is important to ensure that it can
+ be loaded as quickly as possible.
+
+** unw_getcontext() tuned on IA-64.
+
+ The unw_getcontext() routine used to be provided by (GNU) libc
+ (getcontext()). This caused unnecessary overhead (e.g., an
+ unnecessary system-call to sigprocmask()). The new
+ unw_getcontext() only does the work really needed for libunwind and
+ hence performs much better. However, this change implies that
+ programs linked against libunwind v0.97 won't be
+ backwards-compatible with earlier versions (there would be an
+ unresolved symbol for _Uia64_getcontext()).
+
+** Fix NaT-bit handling on IA-64.
+
+ New test-cases have been added to test the handling of the NaT bit
+ (and floating-point NaT values) and all discovered/known bugs have
+ been fixed.
+
+** Initial DWARF-based unwinder for x86.
+
+ There is a beginning for a DWARF-based unwinder for x86. Work for
+ x86-64-support based on this DWARF unwinder is currently underway
+ at IBM and it is expected that this support will be merged into the
+ official tree soon.
+
+\f
+* News for v0.96:
+
+** _Unwind_*() routines defined by the C++ ABI are now included in
+ libunwind.
+
+\f
+* News for v0.95:
+
+** Bigger, better, faster, or so the theory goes.
+
+\f
+* News for v0.93:
+
+** More bug-fixes & improved HP-UX support.
+
+\f
+* News for v0.92:
+
+** Bug-fix release. IA-64 unwinder can now be built with Intel compiler (ECC).
+
+\f
+* News for v0.91:
+
+** Lots of documentation updates
+** Some portability fixes.
+
+\f
+* News for v0.9:
+
+** The libunwind API is mostly feature-complete at this point (hence the
+ version jump from v0.2 to v0.9).
+
+\f
+* News for v0.2:
+
+** Automated configuration/build with autoconf and automake.
+** Added support for building libunwind as a shared library.
+** Added support for remote unwinding.
+** Added support for cross-building.
+** Added two new routines to the API:
+ - unw_is_fpreg()
+ - unw_get_save_loc()
+** Added multi-architecture supports (lets a single application use
+ the unwind libraries for multiple target architectures; this is useful,
+ e.g., useful for building a debugger that can support multiple targets
+ such as x86, ia64, etc.)
+
+\f
+* News for v0.1:
+
+** Added support for exception handling.
+
+\f
+* News for v0.0:
+
+** It's a brand new package.

+-*- mode: Outline -*-
+
+This is version 1.0 of the unwind library. This library supports
+several architecture/operating-system combinations:
+
+ Linux/x86-64: Works well.
+ Linux/x86: Works well.
+ Linux/ARM: Works well.
+ Linux/IA-64: Fully tested and supported.
+ Linux/PARISC: Works well, but C library missing unwind-info.
+ HP-UX/IA-64: Mostly works but known to have some serious limitations.
+ Linux/PPC64: Newly added.
+ Linux/SuperH: Newly added.
+ FreeBSD/i386: Newly added.
+ FreeBSD/x86-64: Newly added (FreeBSD architecture is known as amd64).
+
+
+* General Build Instructions
+
+In general, this library can be built and installed with the following
+commands:
+
+ $ autoreconf -i # Needed only for building from git. Depends on libtool.
+ $ ./configure
+ $ make
+ $ make install prefix=PREFIX
+
+where PREFIX is the installation prefix. By default, a prefix of
+/usr/local is used, such that libunwind.a is installed in
+/usr/local/lib and unwind.h is installed in /usr/local/include. For
+testing, you may want to use a prefix of /usr/local instead.
+
+
+* Building with Intel compiler
+
+** Version 8 and later
+
+Starting with version 8, the preferred name for the IA-64 Intel
+compiler is "icc" (same name as on x86). Thus, the configure-line
+should look like this:
+
+ $ ./configure CC=icc CFLAGS="-g -O3 -ip" CXX=icc CCAS=gcc CCASFLAGS=-g \
+ LDFLAGS="-L$PWD/src/.libs"
+
+
+* Building on HP-UX
+
+For the time being, libunwind must be built with GCC on HP-UX.
+
+libunwind should be configured and installed on HP-UX like this:
+
+ $ ./configure CFLAGS="-g -O2 -mlp64" CXXFLAGS="-g -O2 -mlp64"
+
+Caveat: Unwinding of 32-bit (ILP32) binaries is not supported
+ at the moment.
+
+** Workaround for older versions of GCC
+
+GCC v3.0 and GCC v3.2 ship with a bad version of sys/types.h. The
+workaround is to issue the following commands before running
+"configure":
+
+ $ mkdir $top_dir/include/sys
+ $ cp /usr/include/sys/types.h $top_dir/include/sys
+
+GCC v3.3.2 or later have been fixed and do not require this
+workaround.
+
+* Building for PowerPC64 / Linux
+
+For building for power64 you should use:
+
+ $ ./configure CFLAGS="-g -O2 -m64" CXXFLAGS="-g -O2 -m64"
+
+If your power support altivec registers:
+ $ ./configure CFLAGS="-g -O2 -m64 -maltivec" CXXFLAGS="-g -O2 -m64 -maltivec"
+
+To check if your processor has support for vector registers (altivec):
+ cat /proc/cpuinfo | grep altivec
+and should have something like this:
+ cpu : PPC970, altivec supported
+
+If libunwind seems to not work (backtracing failing), try to compile
+it with -O0, without optimizations. There are some compiler problems
+depending on the version of your gcc.
+
+* Building on FreeBSD
+
+General building instructions apply. To build and execute several tests,
+you need libexecinfo library available in ports as devel/libexecinfo.
+
+Development of the port was done of FreeBSD 8.0-STABLE. The library
+was build with the system compiler that is modified version of gcc 4.2.1,
+as well as the gcc 4.4.3.
+
+* Regression Testing
+
+After building the library, you can run a set of regression tests with:
+
+ $ make check
+
+** Expected results on IA-64 Linux
+
+Unless you have a very recent C library and compiler installed, it is
+currently expected to have the following tests fail on IA-64 Linux:
+
+ Gtest-init (should pass starting with glibc-2.3.x/gcc-3.4)
+ Ltest-init (should pass starting with glibc-2.3.x/gcc-3.4)
+ test-ptrace (should pass starting with glibc-2.3.x/gcc-3.4)
+ run-ia64-test-dyn1 (should pass starting with glibc-2.3.x)
+
+This does not mean that libunwind cannot be used with older compilers
+or C libraries, it just means that for certain corner cases, unwinding
+will fail. Since they're corner cases, it is not likely for
+applications to trigger them.
+
+Note: If you get lots of errors in Gia64-test-nat and Lia64-test-nat, it's
+ almost certainly a sign of an old assembler. The GNU assembler used
+ to encode previous-stack-pointer-relative offsets incorrectly.
+ This bug was fixed on 21-Sep-2004 so any later assembler will be
+ fine.
+
+** Expected results on x86 Linux
+
+The following tests are expected to fail on x86 Linux:
+
+ Gtest-resume-sig (fails to get SIGUSR2)
+ Ltest-resume-sig (likewise)
+ Gtest-dyn1 (no dynamic unwind info support yet)
+ Ltest-dyn1 (no dynamic unwind info support yet)
+ test-setjmp (longjmp() not implemented yet)
+ run-check-namespace (no _Ux86_getcontext yet)
+ test-ptrace
+
+** Expected results on x86-64 Linux
+
+The following tests are expected to fail on x86-64 Linux:
+
+ Gtest-dyn1 (no dynamic unwind info support yet)
+ Ltest-dyn1 (no dynamic unwind info support yet)
+ Gtest-init (see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18743)
+ Ltest-init (likewise)
+ test-async-sig (crashes due to bad unwind-info?)
+ test-setjmp (longjmp() not implemented yet)
+ run-check-namespace (no _Ux86_64_getcontext yet)
+ run-ptrace-mapper (??? investigate)
+ run-ptrace-misc (see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18748
+ and http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18749)
+
+** Expected results on PARISC Linux
+
+Caveat: GCC v3.4 or newer is needed on PA-RISC Linux. Earlier
+versions of the compiler failed to generate the exception-handling
+program header (GNU_EH_FRAME) needed for unwinding.
+
+The following tests are expected to fail on x86-64 Linux:
+
+ Gtest-bt (backtrace truncated at kill() due to lack of unwind-info)
+ Ltest-bt (likewise)
+ Gtest-resume-sig (Gresume.c:my_rt_sigreturn() is wrong somehow)
+ Ltest-resume-sig (likewise)
+ Gtest-init (likewise)
+ Ltest-init (likewise)
+ Gtest-dyn1 (no dynamic unwind info support yet)
+ Ltest-dyn1 (no dynamic unwind info support yet)
+ test-setjmp (longjmp() not implemented yet)
+ run-check-namespace (toolchain doesn't support HIDDEN yet)
+
+** Expected results on HP-UX
+
+"make check" is currently unsupported for HP-UX. You can try to run
+it, but most tests will fail (and some may fail to terminate). The
+only test programs that are known to work at this time are:
+
+ tests/bt
+ tests/Gperf-simple
+ tests/test-proc-info
+ tests/test-static-link
+ tests/Gtest-init
+ tests/Ltest-init
+ tests/Gtest-resume-sig
+ tests/Ltest-resume-sig
+
+** Expected results on PPC64 Linux
+
+"make check" should run with no more than 10 out of 24 tests failed.
+
+
+* Performance Testing
+
+This distribution includes a few simple performance tests which give
+some idea of the basic cost of various libunwind operations. After
+building the library, you can run these tests with the following
+commands:
+
+ $ cd tests
+ $ make perf

+- Update the libunwind man page for the new/fixed cache-flushing behavior.
+ Effectively, that unw_flush_cache() doesn't have to be called by
+ applications except for extraordinary circumstances (e.g., if application
+ implements its own runtime loader).
+- document split local-only/generic libraries and separate libunwind-ptrace.a
+ convenience-library
+- document new "tdep" member in unw_proc_info_t structure
+- for DWARF 2, use a dummy CIE entry with an augmentation that
+ provides the dyn-info-list-address
+
+=== taken care of:
+
+Testing:
+ + ensure that saving r4-r7 in a stacked register properly preserves
+ the NaT bit, even in the face of register-rotation
+ + ensure that IA64_INSN_MOVE_STACKED works correctly in the face of
+ register rotation
+ + on Linux, test access to f32-f127 in a signal handler (e.g., verify
+ that fph partition gets initialized properly)
++ According to Nicholas S. Wourms <nwourms@netscape.net>, adding this to the
+ Makefile.am:
+ AUTOMAKE_OPTIONS = 1.6 subdir-objects
+ ensures that object-files are build in separate subdirectories and that
+ in turn makes it possible for source files in different directories to
+ have the same filename, thus avoiding the need for those ugly -x86, -ia64,
+ etc., postfixes.
++ Switch ia64 (and rest over) to using Debug() instead of debug()
++ implement non-local versions of dwarf_readXX()
++ consolidate mostly architecture-independent code such as
+ unw_get_accessors() into shared files
++ caching is pretty fundamentally broken, what should happen is this:
+ o On unw_init_local()/unw_init_remote(), libunwind should validate
+ that the cached information is still valid and, if not, flush the
+ cache on its own. Rationale: once unw_init_local() has been
+ called, it is clear that the unwind info for the calling thread
+ cannot change (otherwise the program would be buggy anyhow) and
+ hence it is sufficient to validate the cache at this point.
+ Similarly, once unw_init_remote() has been called, the target
+ address space must have been stopped, because the unwinding would
+ otherwise be unreliable anyhow.
+ o glibc currently lacks a feature for dl_iterate_phdr() to support
+ safe caching; I proposed on 12/16/2003 that glibc maintain two
+ atomic counters which get inremented whenever something is added
+ to/removed from the dl_iterate_phdr-list. Once we have such counters,
+ we can use them in libunwind to implement an efficient version of a
+ cache-validation routine.
+ Once this has been fixed, update the libunwind man page accordingly.
+ Effectively, what this means is that unw_flush_cache() doesn't have
+ to be called by applications except for extraordinary circumstances
+ (e.g., if application implements its own runtime loader).
++ man-page for unw_is_fpreg()
++ man-page for _U_dyn_cancel()
++ man-page for _U_dyn_register()
++ global data is not protected by a lock; causes problems if two threads
+ call ia64_init() at almost the same time
++ cache the value of *cfm_loc; each rotate_FOO() call needs it!
++ implement the remote-lookup of the dynamic registration list
++ when doing sigreturn, must restore fp regs (and perhaps other regs) the same
+ way as the (user-level) gate.S sigreturn path does!
++ unw_resume() must at least restore gp (r1)! consider restoring all
+ scratch regs (but what's the performance impact on exception handling?);
+ alternative: restore scratch regs that may be used during procedure
+ call/return (e.g., r8-r11, f8-f11)
++ implement unw_resume() for the case where the current register frame is split
+ across multiple backing stores
++ document restricions on using unw_resume():
++ implement remote cases of unw_resume()
++ test both with UNW_LOCAL_ONLY and without where this makes sense
++ allow region-length (insn_count) in unw_dyn_region_info_t to be negative
+ to indicate counting from the end of the procedure (to make it possible
+ for differently-sized procedures to share the same region list if they
+ share the same prologue/epilogue).
++ it appears that it is currently not possible to read register UNW_IA64_TP;
+ fix that => no, attempts to access r13 will result in access_reg() callbacks,
+ as desired; for local-case, access to r13 will fail though (since
+ getcontext() doesn't, and shouldn't, capture r13)
++ document the special nature of UNW_IA64_GP: read-only, but adjusted
+ automatically if the IP is changed
++ use pthread-mutexes where necessary, atomic ops where possible

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a

+\`configure' configures libunwind 1.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ @<:@@S|@ac_default_prefix@:>@
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ @<:@PREFIX@:>@
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
+ --localstatedir=DIR modifiable single-machine data [PREFIX/var]
+ --libdir=DIR object code libraries [EPREFIX/lib]
+ --includedir=DIR C header files [PREFIX/include]
+ --oldincludedir=DIR C header files for non-gcc [/usr/include]
+ --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
+ --datadir=DIR read-only architecture-independent data [DATAROOTDIR]

+Optional Features:
+ --disable-option-checking ignore unrecognized --enable/--with options
+ --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
+ --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
+ --enable-maintainer-mode enable make rules and dependencies not useful

+ --disable-libtool-lock avoid locking (might break parallel builds)
+ --enable-coredump building libunwind-coredump library
+ --enable-debug turn on debug support (slows down execution)
+ --enable-cxx-exceptions use libunwind to handle C++ exceptions
+ --enable-debug-frame Load the ".debug_frame" section if available
+ --enable-block-signals Block signals before performing mutex operations
+ --enable-conservative-checks
+ Validate all memory addresses before use
+ --enable-msabi-support Enables support for Microsoft ABI extensions
+ --enable-minidebuginfo Enables support for LZMA-compressed symbol tables
+
+Optional Packages:
+ --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
+ --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
+ --with-pic@<:@=PKGS@:>@ try to use only PIC/non-PIC objects @<:@default=use
+ both@:>@
+ --with-gnu-ld assume the C compiler uses GNU ld @<:@default=no@:>@
+ --with-sysroot=DIR Search for dependent libraries within DIR
+ (or the compiler's sysroot if not specified).
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CXX C++ compiler command
+ CXXFLAGS C++ compiler flags
+ CPP C preprocessor
+ CXXCPP C++ preprocessor
+ CCAS assembler compiler command (defaults to CC)
+ CCASFLAGS assembler compiler flags (defaults to CFLAGS)
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+\`configure' configures libunwind 1.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ @<:@@S|@ac_default_prefix@:>@
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ @<:@PREFIX@:>@
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CXX C++ compiler command
+ CXXFLAGS C++ compiler flags
+ CPP C preprocessor
+ CXXCPP C++ preprocessor
+ CCAS assembler compiler command (defaults to CC)
+ CCASFLAGS assembler compiler flags (defaults to CFLAGS)
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+ -dlopen FILE \`-dlpreopen' FILE if it cannot be dlopened at runtime
+ -dlpreopen FILE link in FILE and add its symbols to lt_preloaded_symbols

+ -module build a library that can dlopened
+ -no-fast-install disable the fast-install mode
+ -no-install link a not-installable executable
+ -no-undefined declare that a library does not refer to external symbols
+ -o OUTPUT-FILE create OUTPUT-FILE from the specified objects
+ -release RELEASE specify package release information
+ -rpath LIBDIR the created library will eventually be installed in LIBDIR

+ -static do not do any dynamic linking of libtool libraries
+ -version-info CURRENT[:REVISION[:AGE]]

+object files.
+
+If the OUTPUT-FILE ends in \`.la', then a libtool library is created,
+only library objects (\`.lo' files) may be specified, and \`-rpath' is
+required, except when creating a convenience library.
+
+If OUTPUT-FILE ends in \`.a' or \`.lib', then a standard library is created

+\`configure' configures libunwind 1.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]

+ --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
+ --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
+ --enable-maintainer-mode enable make rules and dependencies not useful

+ --disable-dependency-tracking speeds up one-time build
+ --enable-dependency-tracking do not reject slow dependency extractors
+ --enable-shared[=PKGS] build shared libraries [default=yes]
+ --enable-static[=PKGS] build static libraries [default=yes]
+ --enable-fast-install[=PKGS]
+ optimize for fast installation [default=yes]
+ --disable-libtool-lock avoid locking (might break parallel builds)
+ --enable-coredump building libunwind-coredump library
+ --enable-debug turn on debug support (slows down execution)
+ --enable-cxx-exceptions use libunwind to handle C++ exceptions
+ --enable-debug-frame Load the ".debug_frame" section if available
+ --enable-block-signals Block signals before performing mutex operations
+ --enable-conservative-checks
+ Validate all memory addresses before use
+ --enable-msabi-support Enables support for Microsoft ABI extensions
+ --enable-minidebuginfo Enables support for LZMA-compressed symbol tables
+
+Optional Packages:
+ --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
+ --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
+ --with-pic[=PKGS] try to use only PIC/non-PIC objects [default=use
+ both]
+ --with-gnu-ld assume the C compiler uses GNU ld [default=no]
+ --with-sysroot=DIR Search for dependent libraries within DIR
+ (or the compiler's sysroot if not specified).
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CXX C++ compiler command
+ CXXFLAGS C++ compiler flags
+ CPP C preprocessor
+ CXXCPP C++ preprocessor
+ CCAS assembler compiler command (defaults to CC)
+ CCASFLAGS assembler compiler flags (defaults to CFLAGS)
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+The central data structure of the unwind API is the unwind cursor.
+This structure tracks the register contents. The unwind API defines a
+handful of well-known frame "registers":
+
+ - ip: the instruction pointer (pc)
+ - rp: the return pointer (rp, aka "return address" or "return link")
+ - sp: the stack pointer (memory stack pointer, in the case of ia64)
+ - fp: the frame pointer
+ - first_ip: the starting address of the current "procedure"
+ - handler: a pointer to an architecture & language-specific
+ "personality" routine
+ - lsda: a pointer to an architecture & language-specific
+ data-area
+
+The API defines no well-known preserved registers. Each architecture
+can define additional registers as needed. Of course, a portable
+application may only rely on well-known registers. The names for
+preserved registers are defined in the architecture-specific header
+file <unwind-ARCH.h>. For example, to get the IA-64-specific register
+names, an application would do:
+
+ #include <unwind-ia64.h>
+
+The API is designed to handle two primary cases: unwinding within the
+current (local) process and unwinding of another ("remote") process
+(e.g., through ptrace()). In the local case, the initial machine
+state is captured by an unwind context (currently the same as
+ucontext_t). In the remote case, the initial machine state is
+captured by an unwind accessor structure, which provides callback
+routines for reading/writing memory and registers and for obtaining
+unwind information.
+
+Once a cursor has been initialized, you can step through the call
+chain with the unw_step() routine. The frame registers and the
+preserved state can then be accessed with unw_get_reg() or modified
+with unw_set_reg(). For floating-point registers, there are separate
+unw_get_fpreg() and unw_set_fpreg() routines (on some arches, e.g.,
+Alpha, these could be just aliases for unw_{g,s}et_reg()). The
+unw_resume() routine can be used to resume execution at an arbitrary
+point in the call-chain (as identified by an unwind cursor). This is
+intended for exception handling and, at least for now, the intention
+is to support this routine only for the local case. Kevin, if you
+feel gdb could benefit from such a routine, I'd be interested to hear
+about it.
+
+Note that it is perfectly legal to make copies of the unwind cursor.
+This makes it possible, e.g., to obtain an unwind context, modify the
+state in an earlier call frame, and then resume execution at the point
+at which the unwind context was captured.
+
+Here is a quick example of how to use the unwind API to do a simple
+stack trace:
+
+ unw_cursor_t cursor;
+ unw_word_t ip, sp;
+ unw_context_t uc;
+
+ unw_getcontext(&uc);
+ unw_init_local(&cursor, &uc);
+ do
+ {
+ unw_get_reg(&cursor, UNW_REG_IP, &ip);
+ unw_get_reg(&cursor, UNW_REG_SP, &sp);
+ printf ("ip=%016lx sp=%016lx\n", ip, sp);
+ }
+ while (unw_step (&cursor) > 0);
+
+Note that this particular example should work on pretty much any
+architecture, as it doesn't rely on any arch-specific registers.
+
+* Multiarchitecture support
+
+If libunwind is configured for a target other than the local (native)
+host, the library is installed as libunwind-$ARCH, where $ARCH is
+the target architecture name (e.g., ia32, ia64, or alpha). Similarly,
+the header file is installed as libunwind-$ARCH.
+
+With this setup, an application should:
+
+ - include <libunwind.h>, and
+ - link against -lunwind
+
+if the application needs to use the unwinder of the host. An
+application wanting to use the unwinder for a different target (e.g.,
+a cross-debugger) should:
+
+ - include <libunwind-$ARCH.h>, and
+ - link against -lunwind-$ARCH
+
+The global symbols exported by -lunwind-$ARCH are unique such that the
+same application can be linked against the separate unwind libraries
+of multiple targets. However, a single compilation unit can include
+the header file for only one target. For example, foo.c might include
+<libunwind-ia64.h> and bar.c might include <libunwind.h> and the
+entire application would have to be linked against both -lunwind and
+-lunwind-ia64.
+
+Note: the unwind header files of all targets have a common dependency
+on libunwind-common.h. To avoid version conflicts, it is necessary to
+ensure that the unwind libraries for all targets were derived from the
+same release of libunwind. That is, if the unwind library for one
+target is upgraded to a newer version, the libraries for all other
+targets also need to be upgraded.
+
+Note 2: The assumption is that a cross-unwinder can handle all
+interesting flavors of a target. For example, the unwinder for the
+ia64 target is expected to be able to handle both Linux and HP-UX.
+
+* IA-64 Specific Information
+
+Apart from the normal frame-registers, the IA-64 implementation of
+libunwind provides the means to access the current value of the
+register backing store pointer (bsp). One quirk with this
+frame-register is that it corresponds to the address that would be in
+register ar.bsp after flushing the current register stack to the
+backing store (i.e., as if a "flushrs" instruction had been executed).
+Of course, given this value and the contents of the current frame
+marker (CFM), it's easy to calculate the original value of ar.bsp:
+
+ unw_word_t cfm, bsp, bsp_after_flushrs, sof;
+
+ unw_get_reg (&cursor, UNW_IA64_BSP, &bsp_after_flushrs);
+ unw_get_reg (&cursor, UNW_IA64_CFM, &cfm);
+ bsp = ia64_rse_skip_regs (bsp_after_flushrs, -(cfm & 0x7f));

+.TH "LIBUNWIND\-DYNAMIC" "3" "16 August 2007" "Programming Library " "Programming Library "
+.SH NAME
+libunwind\-dynamic
+\-\- libunwind\-support for runtime\-generated code
+.PP
+.SH INTRODUCTION
+
+.PP
+For libunwind
+to do its job, it needs to be able to reconstruct
+the \fIframe state\fP
+of each frame in a call\-chain. The frame state
+describes the subset of the machine\-state that consists of the
+\fIframe registers\fP
+(typically the instruction\-pointer and the
+stack\-pointer) and all callee\-saved registers (preserved registers).
+The frame state describes each register either by providing its
+current value (for frame registers) or by providing the location at
+which the current value is stored (callee\-saved registers).
+.PP
+For statically generated code, the compiler normally takes care of
+emitting \fIunwind\-info\fP
+which provides the minimum amount of
+information needed to reconstruct the frame\-state for each instruction
+in a procedure. For dynamically generated code, the runtime code
+generator must use the dynamic unwind\-info interface provided by
+libunwind
+to supply the equivalent information. This manual
+page describes the format of this information in detail.
+.PP
+For the purpose of this discussion, a \fIprocedure\fP
+is defined to
+be an arbitrary piece of \fIcontiguous\fP
+code. Normally, each
+procedure directly corresponds to a function in the source\-language
+but this is not strictly required. For example, a runtime
+code\-generator could translate a given function into two separate
+(discontiguous) procedures: one for frequently\-executed (hot) code and
+one for rarely\-executed (cold) code. Similarly, simple
+source\-language functions (usually leaf functions) may get translated
+into code for which the default unwind\-conventions apply and for such
+code, it is not strictly necessary to register dynamic unwind\-info.
+.PP
+A procedure logically consists of a sequence of \fIregions\fP\&.
+Regions are nested in the sense that the frame state at the end of one
+region is, by default, assumed to be the frame state for the next
+region. Each region is thought of as being divided into a
+\fIprologue\fP,
+a \fIbody\fP,
+and an \fIepilogue\fP\&.
+Each of them
+can be empty. If non\-empty, the prologue sets up the frame state for
+the body. For example, the prologue may need to allocate some space
+on the stack and save certain callee\-saved registers. The body
+performs the actual work of the procedure but does not change the
+frame state in any way. If non\-empty, the epilogue restores the
+previous frame state and as such it undoes or cancels the effect of
+the prologue. In fact, a single epilogue may undo the effect of the
+prologues of several (nested) regions.
+.PP
+We should point out that even though the prologue, body, and epilogue
+are logically separate entities, optimizing code\-generators will
+generally interleave instructions from all three entities. For this
+reason, the dynamic unwind\-info interface of libunwind
+makes no
+distinction whatsoever between prologue and body. Similarly, the
+exact set of instructions that make up an epilogue is also irrelevant.
+The only point in the epilogue that needs to be described explicitly
+by the dynamic unwind\-info is the point at which the stack\-pointer
+gets restored. The reason this point needs to be described is that
+once the stack\-pointer is restored, all values saved in the
+deallocated portion of the stack frame become invalid and hence
+libunwind
+needs to know about it. The portion of the frame
+state not saved on the stack is assume to remain valid through the end
+of the region. For this reason, there is usually no need to describe
+instructions which restore the contents of callee\-saved registers.
+.PP
+Within a region, each instruction that affects the frame state in some
+fashion needs to be described with an operation descriptor. For this
+purpose, each instruction in the region is assigned a unique index.
+Exactly how this index is derived depends on the architecture. For
+example, on RISC and EPIC\-style architecture, instructions have a
+fixed size so it\&'s possible to simply number the instructions. In
+contrast, most CISC use variable\-length instruction encodings, so it
+is usually necessary to use a byte\-offset as the index. Given the
+instruction index, the operation descriptor specifies the effect of
+the instruction in an abstract manner. For example, it might express
+that the instruction stores calle\-saved register r1
+at offset 16
+in the stack frame.
+.PP
+.SH PROCEDURES
+
+.PP
+A runtime code\-generator registers the dynamic unwind\-info of a
+procedure by setting up a structure of type unw_dyn_info_t
+and calling _U_dyn_register(),
+passing the address of the
+structure as the sole argument. The members of the
+unw_dyn_info_t
+structure are described below:
+.TP
+void *next
+ Private to libunwind\&.
+Must not be used
+by the application.
+.TP
+void *prev
+ Private to libunwind\&.
+Must not be used
+by the application.
+.TP
+unw_word_t start_ip
+ The start\-address of the
+instructions of the procedure (remember: procedure are defined to be
+contiguous pieces of code, so a single code\-range is sufficient).
+.TP
+unw_word_t end_ip
+ The end\-address of the
+instructions of the procedure (non\-inclusive, that is,
+end_ip\-start_ip
+is the size of the procedure in
+bytes).
+.TP
+unw_word_t gp
+ The global\-pointer value in use
+for this procedure. The exact meaing of the global\-pointer is
+architecture\-specific and on some architecture, it is not used at
+all.
+.TP
+int32_t format
+ The format of the unwind\-info.
+This member can be one of UNW_INFO_FORMAT_DYNAMIC,
+UNW_INFO_FORMAT_TABLE,
+or
+UNW_INFO_FORMAT_REMOTE_TABLE\&.
+.TP
+union u
+ This union contains one sub\-member
+structure for every possible unwind\-info format:
+.RS
+.TP
+unw_dyn_proc_info_t pi
+ This member is used
+for format UNW_INFO_FORMAT_DYNAMIC\&.
+.TP
+unw_dyn_table_info_t ti
+ This member is used
+for format UNW_INFO_FORMAT_TABLE\&.
+.TP
+unw_dyn_remote_table_info_t rti
+ This member
+is used for format UNW_INFO_FORMAT_REMOTE_TABLE\&.
+.RE
+.RS
+.PP
+The format of these sub\-members is described in detail below.
+.RE
+.PP
+.SS PROC\-INFO FORMAT
+.PP
+This is the preferred dynamic unwind\-info format and it is generally
+the one used by full\-blown runtime code\-generators. In this format,
+the details of a procedure are described by a structure of type
+unw_dyn_proc_info_t\&.
+This structure contains the following
+members:
+.PP
+.RE
+.TP
+unw_word_t name_ptr
+ The address of a
+(human\-readable) name of the procedure or 0 if no such name is
+available. If non\-zero, The string stored at this address must be
+ASCII NUL terminated. For source languages that use name\-mangling
+(such as C++ or Java) the string stored at this address should be
+the \fIdemangled\fP
+version of the name.
+.PP
+.TP
+unw_word_t handler
+ The address of the
+personality\-routine for this procedure. Personality\-routines are
+used in conjunction with exception handling. See the C++ ABI draft
+(http://www.codesourcery.com/cxx\-abi/) for an overview and a
+description of the personality routine. If the procedure has no
+personality routine, handler
+must be set to 0.
+.PP
+.TP
+uint32_t flags
+ A bitmask of flags. At the
+moment, no flags have been defined and this member must be
+set to 0.
+.PP
+.TP
+unw_dyn_region_info_t *regions
+ A NULL\-terminated
+linked list of region\-descriptors. See section ``Region
+descriptors\&'' below for more details.
+.PP
+.SS TABLE\-INFO FORMAT
+.PP
+This format is generally used when the dynamically generated code was
+derived from static code and the unwind\-info for the dynamic and the
+static versions is identical. For example, this format can be useful
+when loading statically\-generated code into an address\-space in a
+non\-standard fashion (i.e., through some means other than
+dlopen()).
+In this format, the details of a group of procedures
+is described by a structure of type unw_dyn_table_info\&.
+This structure contains the following members:
+.PP
+.TP
+unw_word_t name_ptr
+ The address of a
+(human\-readable) name of the procedure or 0 if no such name is
+available. If non\-zero, The string stored at this address must be
+ASCII NUL terminated. For source languages that use name\-mangling
+(such as C++ or Java) the string stored at this address should be
+the \fIdemangled\fP
+version of the name.
+.PP
+.TP
+unw_word_t segbase
+ The segment\-base value
+that needs to be added to the segment\-relative values stored in the
+unwind\-info. The exact meaning of this value is
+architecture\-specific.
+.PP
+.TP
+unw_word_t table_len
+ The length of the
+unwind\-info (table_data)
+counted in units of words
+(unw_word_t).
+.PP
+.TP
+unw_word_t table_data
+ A pointer to the actual
+data encoding the unwind\-info. The exact format is
+architecture\-specific (see architecture\-specific sections below).
+.PP
+.SS REMOTE TABLE\-INFO FORMAT
+.PP
+The remote table\-info format has the same basic purpose as the regular
+table\-info format. The only difference is that when libunwind
+uses the unwind\-info, it will keep the table data in the target
+address\-space (which may be remote). Consequently, the type of the
+table_data
+member is unw_word_t
+rather than a pointer.
+This implies that libunwind
+will have to access the table\-data
+via the address\-space\&'s access_mem()
+call\-back, rather than
+through a direct memory reference.
+.PP
+From the point of view of a runtime\-code generator, the remote
+table\-info format offers no advantage and it is expected that such
+generators will describe their procedures either with the proc\-info
+format or the normal table\-info format. The main reason that the
+remote table\-info format exists is to enable the
+address\-space\-specific find_proc_info()
+callback (see
+unw_create_addr_space(3))
+to return unwind tables whose
+data remains in remote memory. This can speed up unwinding (e.g., for
+a debugger) because it reduces the amount of data that needs to be
+loaded from remote memory.
+.PP
+.SH REGIONS DESCRIPTORS
+
+.PP
+A region descriptor is a variable length structure that describes how
+each instruction in the region affects the frame state. Of course,
+most instructions in a region usualy do not change the frame state and
+for those, nothing needs to be recorded in the region descriptor. A
+region descriptor is a structure of type
+unw_dyn_region_info_t
+and has the following members:
+.TP
+unw_dyn_region_info_t *next
+ A pointer to the
+next region. If this is the last region, next
+is NULL\&.
+.TP
+int32_t insn_count
+ The length of the region in
+instructions. Each instruction is assumed to have a fixed size (see
+architecture\-specific sections for details). The value of
+insn_count
+may be negative in the last region of a procedure
+(i.e., it may be negative only if next
+is NULL).
+A
+negative value indicates that the region covers the last \fIN\fP
+instructions of the procedure, where \fIN\fP
+is the absolute value
+of insn_count\&.
+.TP
+uint32_t op_count
+ The (allocated) length of
+the op_count
+array.
+.TP
+unw_dyn_op_t op
+ An array of dynamic unwind
+directives. See Section ``Dynamic unwind directives\&'' for a
+description of the directives.
+.PP
+A region descriptor with an insn_count
+of zero is an
+\fIempty region\fP
+and such regions are perfectly legal. In fact,
+empty regions can be useful to establish a particular frame state
+before the start of another region.
+.PP
+A single region list can be shared across multiple procedures provided
+those procedures share a common prologue and epilogue (their bodies
+may differ, of course). Normally, such procedures consist of a canned
+prologue, the body, and a canned epilogue. This could be described by
+two regions: one covering the prologue and one covering the epilogue.
+Since the body length is variable, the latter region would need to
+specify a negative value in insn_count
+such that
+libunwind
+knows that the region covers the end of the procedure
+(up to the address specified by end_ip).
+.PP
+The region descriptor is a variable length structure to make it
+possible to allocate all the necessary memory with a single
+memory\-allocation request. To facilitate the allocation of a region
+descriptors libunwind
+provides a helper routine with the
+following synopsis:
+.PP
+size_t
+_U_dyn_region_size(int
+op_count);
+.PP
+This routine returns the number of bytes needed to hold a region
+descriptor with space for op_count
+unwind directives. Note
+that the length of the op
+array does not have to match exactly
+with the number of directives in a region. Instead, it is sufficient
+if the op
+array contains at least as many entries as there are
+directives, since the end of the directives can always be indicated
+with the UNW_DYN_STOP
+directive.
+.PP
+.SH DYNAMIC UNWIND DIRECTIVES
+
+.PP
+A dynamic unwind directive describes how the frame state changes
+at a particular point within a region. The description is in
+the form of a structure of type unw_dyn_op_t\&.
+This
+structure has the following members:
+.TP
+int8_t tag
+ The operation tag. Must be one
+of the unw_dyn_operation_t
+values described below.
+.TP
+int8_t qp
+ The qualifying predicate that controls
+whether or not this directive is active. This is useful for
+predicated architecturs such as IA\-64 or ARM, where the contents of
+another (callee\-saved) register determines whether or not an
+instruction is executed (takes effect). If the directive is always
+active, this member should be set to the manifest constant
+_U_QP_TRUE
+(this constant is defined for all
+architectures, predicated or not).
+.TP
+int16_t reg
+ The number of the register affected
+by the instruction.
+.TP
+int32_t when
+ The region\-relative number of
+the instruction to which this directive applies. For example,
+a value of 0 means that the effect described by this directive
+has taken place once the first instruction in the region has
+executed.
+.TP
+unw_word_t val
+ The value to be applied by the
+operation tag. The exact meaning of this value varies by tag. See

+\section{Introduction}
+
+For \Prog{libunwind} to do its job, it needs to be able to reconstruct
+the \emph{frame state} of each frame in a call-chain. The frame state
+describes the subset of the machine-state that consists of the
+\emph{frame registers} (typically the instruction-pointer and the
+stack-pointer) and all callee-saved registers (preserved registers).
+The frame state describes each register either by providing its
+current value (for frame registers) or by providing the location at
+which the current value is stored (callee-saved registers).
+
+For statically generated code, the compiler normally takes care of
+emitting \emph{unwind-info} which provides the minimum amount of
+information needed to reconstruct the frame-state for each instruction
+in a procedure. For dynamically generated code, the runtime code
+generator must use the dynamic unwind-info interface provided by
+\Prog{libunwind} to supply the equivalent information. This manual
+page describes the format of this information in detail.
+
+For the purpose of this discussion, a \emph{procedure} is defined to
+be an arbitrary piece of \emph{contiguous} code. Normally, each
+procedure directly corresponds to a function in the source-language
+but this is not strictly required. For example, a runtime
+code-generator could translate a given function into two separate
+(discontiguous) procedures: one for frequently-executed (hot) code and
+one for rarely-executed (cold) code. Similarly, simple
+source-language functions (usually leaf functions) may get translated
+into code for which the default unwind-conventions apply and for such
+code, it is not strictly necessary to register dynamic unwind-info.
+
+A procedure logically consists of a sequence of \emph{regions}.
+Regions are nested in the sense that the frame state at the end of one
+region is, by default, assumed to be the frame state for the next
+region. Each region is thought of as being divided into a
+\emph{prologue}, a \emph{body}, and an \emph{epilogue}. Each of them
+can be empty. If non-empty, the prologue sets up the frame state for
+the body. For example, the prologue may need to allocate some space
+on the stack and save certain callee-saved registers. The body
+performs the actual work of the procedure but does not change the
+frame state in any way. If non-empty, the epilogue restores the
+previous frame state and as such it undoes or cancels the effect of
+the prologue. In fact, a single epilogue may undo the effect of the
+prologues of several (nested) regions.
+
+We should point out that even though the prologue, body, and epilogue
+are logically separate entities, optimizing code-generators will
+generally interleave instructions from all three entities. For this
+reason, the dynamic unwind-info interface of \Prog{libunwind} makes no
+distinction whatsoever between prologue and body. Similarly, the
+exact set of instructions that make up an epilogue is also irrelevant.
+The only point in the epilogue that needs to be described explicitly
+by the dynamic unwind-info is the point at which the stack-pointer
+gets restored. The reason this point needs to be described is that
+once the stack-pointer is restored, all values saved in the
+deallocated portion of the stack frame become invalid and hence
+\Prog{libunwind} needs to know about it. The portion of the frame
+state not saved on the stack is assume to remain valid through the end
+of the region. For this reason, there is usually no need to describe
+instructions which restore the contents of callee-saved registers.
+
+Within a region, each instruction that affects the frame state in some
+fashion needs to be described with an operation descriptor. For this
+purpose, each instruction in the region is assigned a unique index.
+Exactly how this index is derived depends on the architecture. For
+example, on RISC and EPIC-style architecture, instructions have a
+fixed size so it's possible to simply number the instructions. In
+contrast, most CISC use variable-length instruction encodings, so it
+is usually necessary to use a byte-offset as the index. Given the
+instruction index, the operation descriptor specifies the effect of
+the instruction in an abstract manner. For example, it might express
+that the instruction stores calle-saved register \Var{r1} at offset 16
+in the stack frame.
+
+\section{Procedures}
+
+A runtime code-generator registers the dynamic unwind-info of a
+procedure by setting up a structure of type \Type{unw\_dyn\_info\_t}
+and calling \Func{\_U\_dyn\_register}(), passing the address of the
+structure as the sole argument. The members of the
+\Type{unw\_dyn\_info\_t} structure are described below:
+\begin{itemize}
+\item[\Type{void~*}next] Private to \Prog{libunwind}. Must not be used
+ by the application.
+\item[\Type{void~*}prev] Private to \Prog{libunwind}. Must not be used
+ by the application.
+\item[\Type{unw\_word\_t} \Var{start\_ip}] The start-address of the
+ instructions of the procedure (remember: procedure are defined to be
+ contiguous pieces of code, so a single code-range is sufficient).
+\item[\Type{unw\_word\_t} \Var{end\_ip}] The end-address of the
+ instructions of the procedure (non-inclusive, that is,
+ \Var{end\_ip}-\Var{start\_ip} is the size of the procedure in
+ bytes).
+\item[\Type{unw\_word\_t} \Var{gp}] The global-pointer value in use
+ for this procedure. The exact meaing of the global-pointer is
+ architecture-specific and on some architecture, it is not used at
+ all.
+\item[\Type{int32\_t} \Var{format}] The format of the unwind-info.
+ This member can be one of \Const{UNW\_INFO\_FORMAT\_DYNAMIC},
+ \Const{UNW\_INFO\_FORMAT\_TABLE}, or
+ \Const{UNW\_INFO\_FORMAT\_REMOTE\_TABLE}.
+\item[\Type{union} \Var{u}] This union contains one sub-member
+ structure for every possible unwind-info format:
+ \begin{description}
+ \item[\Type{unw\_dyn\_proc\_info\_t} \Var{pi}] This member is used
+ for format \Const{UNW\_INFO\_FORMAT\_DYNAMIC}.
+ \item[\Type{unw\_dyn\_table\_info\_t} \Var{ti}] This member is used
+ for format \Const{UNW\_INFO\_FORMAT\_TABLE}.
+ \item[\Type{unw\_dyn\_remote\_table\_info\_t} \Var{rti}] This member
+ is used for format \Const{UNW\_INFO\_FORMAT\_REMOTE\_TABLE}.
+ \end{description}\
+ The format of these sub-members is described in detail below.
+\end{itemize}
+
+\subsection{Proc-info format}
+
+This is the preferred dynamic unwind-info format and it is generally
+the one used by full-blown runtime code-generators. In this format,
+the details of a procedure are described by a structure of type
+\Type{unw\_dyn\_proc\_info\_t}. This structure contains the following
+members:
+\begin{description}
+
+\item[\Type{unw\_word\_t} \Var{name\_ptr}] The address of a
+ (human-readable) name of the procedure or 0 if no such name is
+ available. If non-zero, The string stored at this address must be
+ ASCII NUL terminated. For source languages that use name-mangling
+ (such as C++ or Java) the string stored at this address should be
+ the \emph{demangled} version of the name.
+
+\item[\Type{unw\_word\_t} \Var{handler}] The address of the
+ personality-routine for this procedure. Personality-routines are
+ used in conjunction with exception handling. See the C++ ABI draft
+ (http://www.codesourcery.com/cxx-abi/) for an overview and a
+ description of the personality routine. If the procedure has no
+ personality routine, \Var{handler} must be set to 0.
+
+\item[\Type{uint32\_t} \Var{flags}] A bitmask of flags. At the
+ moment, no flags have been defined and this member must be
+ set to 0.
+
+\item[\Type{unw\_dyn\_region\_info\_t~*}\Var{regions}] A NULL-terminated
+ linked list of region-descriptors. See section ``Region
+ descriptors'' below for more details.
+
+\end{description}
+
+\subsection{Table-info format}
+
+This format is generally used when the dynamically generated code was
+derived from static code and the unwind-info for the dynamic and the
+static versions is identical. For example, this format can be useful
+when loading statically-generated code into an address-space in a
+non-standard fashion (i.e., through some means other than
+\Func{dlopen}()). In this format, the details of a group of procedures
+is described by a structure of type \Type{unw\_dyn\_table\_info}.
+This structure contains the following members:
+\begin{description}
+
+\item[\Type{unw\_word\_t} \Var{name\_ptr}] The address of a
+ (human-readable) name of the procedure or 0 if no such name is
+ available. If non-zero, The string stored at this address must be
+ ASCII NUL terminated. For source languages that use name-mangling
+ (such as C++ or Java) the string stored at this address should be
+ the \emph{demangled} version of the name.
+
+\item[\Type{unw\_word\_t} \Var{segbase}] The segment-base value
+ that needs to be added to the segment-relative values stored in the
+ unwind-info. The exact meaning of this value is
+ architecture-specific.
+
+\item[\Type{unw\_word\_t} \Var{table\_len}] The length of the
+ unwind-info (\Var{table\_data}) counted in units of words
+ (\Type{unw\_word\_t}).
+
+\item[\Type{unw\_word\_t} \Var{table\_data}] A pointer to the actual
+ data encoding the unwind-info. The exact format is
+ architecture-specific (see architecture-specific sections below).
+
+\end{description}
+
+\subsection{Remote table-info format}
+
+The remote table-info format has the same basic purpose as the regular
+table-info format. The only difference is that when \Prog{libunwind}
+uses the unwind-info, it will keep the table data in the target
+address-space (which may be remote). Consequently, the type of the
+\Var{table\_data} member is \Type{unw\_word\_t} rather than a pointer.
+This implies that \Prog{libunwind} will have to access the table-data
+via the address-space's \Func{access\_mem}() call-back, rather than
+through a direct memory reference.
+
+From the point of view of a runtime-code generator, the remote
+table-info format offers no advantage and it is expected that such
+generators will describe their procedures either with the proc-info
+format or the normal table-info format. The main reason that the
+remote table-info format exists is to enable the
+address-space-specific \Func{find\_proc\_info}() callback (see
+\SeeAlso{unw\_create\_addr\_space}(3)) to return unwind tables whose
+data remains in remote memory. This can speed up unwinding (e.g., for
+a debugger) because it reduces the amount of data that needs to be
+loaded from remote memory.
+
+\section{Regions descriptors}
+
+A region descriptor is a variable length structure that describes how
+each instruction in the region affects the frame state. Of course,
+most instructions in a region usualy do not change the frame state and
+for those, nothing needs to be recorded in the region descriptor. A
+region descriptor is a structure of type
+\Type{unw\_dyn\_region\_info\_t} and has the following members:
+\begin{description}
+\item[\Type{unw\_dyn\_region\_info\_t~*}\Var{next}] A pointer to the
+ next region. If this is the last region, \Var{next} is \Const{NULL}.
+\item[\Type{int32\_t} \Var{insn\_count}] The length of the region in
+ instructions. Each instruction is assumed to have a fixed size (see
+ architecture-specific sections for details). The value of
+ \Var{insn\_count} may be negative in the last region of a procedure
+ (i.e., it may be negative only if \Var{next} is \Const{NULL}). A
+ negative value indicates that the region covers the last \emph{N}
+ instructions of the procedure, where \emph{N} is the absolute value
+ of \Var{insn\_count}.
+\item[\Type{uint32\_t} \Var{op\_count}] The (allocated) length of
+ the \Var{op\_count} array.
+\item[\Type{unw\_dyn\_op\_t} \Var{op}] An array of dynamic unwind
+ directives. See Section ``Dynamic unwind directives'' for a
+ description of the directives.
+\end{description}
+A region descriptor with an \Var{insn\_count} of zero is an
+\emph{empty region} and such regions are perfectly legal. In fact,
+empty regions can be useful to establish a particular frame state
+before the start of another region.
+
+A single region list can be shared across multiple procedures provided
+those procedures share a common prologue and epilogue (their bodies
+may differ, of course). Normally, such procedures consist of a canned
+prologue, the body, and a canned epilogue. This could be described by
+two regions: one covering the prologue and one covering the epilogue.
+Since the body length is variable, the latter region would need to
+specify a negative value in \Var{insn\_count} such that
+\Prog{libunwind} knows that the region covers the end of the procedure
+(up to the address specified by \Var{end\_ip}).
+
+The region descriptor is a variable length structure to make it
+possible to allocate all the necessary memory with a single
+memory-allocation request. To facilitate the allocation of a region
+descriptors \Prog{libunwind} provides a helper routine with the
+following synopsis:
+
+\noindent
+\Type{size\_t} \Func{\_U\_dyn\_region\_size}(\Type{int} \Var{op\_count});
+
+This routine returns the number of bytes needed to hold a region
+descriptor with space for \Var{op\_count} unwind directives. Note
+that the length of the \Var{op} array does not have to match exactly
+with the number of directives in a region. Instead, it is sufficient
+if the \Var{op} array contains at least as many entries as there are
+directives, since the end of the directives can always be indicated
+with the \Const{UNW\_DYN\_STOP} directive.
+
+\section{Dynamic unwind directives}
+
+A dynamic unwind directive describes how the frame state changes
+at a particular point within a region. The description is in
+the form of a structure of type \Type{unw\_dyn\_op\_t}. This
+structure has the following members:
+\begin{description}
+\item[\Type{int8\_t} \Var{tag}] The operation tag. Must be one
+ of the \Type{unw\_dyn\_operation\_t} values described below.
+\item[\Type{int8\_t} \Var{qp}] The qualifying predicate that controls
+ whether or not this directive is active. This is useful for
+ predicated architecturs such as IA-64 or ARM, where the contents of
+ another (callee-saved) register determines whether or not an
+ instruction is executed (takes effect). If the directive is always
+ active, this member should be set to the manifest constant
+ \Const{\_U\_QP\_TRUE} (this constant is defined for all
+ architectures, predicated or not).
+\item[\Type{int16\_t} \Var{reg}] The number of the register affected
+ by the instruction.
+\item[\Type{int32\_t} \Var{when}] The region-relative number of
+ the instruction to which this directive applies. For example,
+ a value of 0 means that the effect described by this directive
+ has taken place once the first instruction in the region has
+ executed.
+\item[\Type{unw\_word\_t} \Var{val}] The value to be applied by the
+ operation tag. The exact meaning of this value varies by tag. See
+ Section ``Operation tags'' below.
+\end{description}
+It is perfectly legitimate to specify multiple dynamic unwind
+directives with the same \Var{when} value, if a particular instruction
+has a complex effect on the frame state.
+
+Empty regions by definition contain no actual instructions and as such
+the directives are not tied to a particular instruction. By
+convention, the \Var{when} member should be set to 0, however.
+
+There is no need for the dynamic unwind directives to appear
+in order of increasing \Var{when} values. If the directives happen to
+be sorted in that order, it may result in slightly faster execution,
+but a runtime code-generator should not go to extra lengths just to
+ensure that the directives are sorted.
+
+IMPLEMENTATION NOTE: should \Prog{libunwind} implementations for
+certain architectures prefer the list of unwind directives to be
+sorted, it is recommended that such implementations first check
+whether the list happens to be sorted already and, if not, sort the
+directives explicitly before the first use. With this approach, the
+overhead of explicit sorting is only paid when there is a real benefit
+and if the runtime code-generator happens to generated sorted lists
+naturally, the performance penalty is limited to a simple O(N) check.
+
+\subsection{Operations tags}
+
+The possible operation tags are defined by enumeration type
+\Type{unw\_dyn\_operation\_t} which defines the following
+values:
+\begin{description}
+
+\item[\Const{UNW\_DYN\_STOP}] Marks the end of the dynamic unwind
+ directive list. All remaining entries in the \Var{op} array of the
+ region-descriptor are ignored. This tag is guaranteed to have a
+ value of 0.
+
+\item[\Const{UNW\_DYN\_SAVE\_REG}] Marks an instruction which saves
+ register \Var{reg} to register \Var{val}.
+
+\item[\Const{UNW\_DYN\_SPILL\_FP\_REL}] Marks an instruction which
+ spills register \Var{reg} to a frame-pointer-relative location. The
+ frame-pointer-relative offset is given by the value stored in member
+ \Var{val}. See the architecture-specific sections for a description
+ of the stack frame layout.
+
+\item[\Const{UNW\_DYN\_SPILL\_SP\_REL}] Marks an instruction which
+ spills register \Var{reg} to a stack-pointer-relative location. The
+ stack-pointer-relative offset is given by the value stored in member
+ \Var{val}. See the architecture-specific sections for a description
+ of the stack frame layout.
+
+\item[\Const{UNW\_DYN\_ADD}] Marks an instruction which adds

+.SH NAME
+libunwind\-ia64
+\-\- IA\-64\-specific support in libunwind
+.PP
+.SH INTRODUCTION
+
+.PP
+The IA\-64 version of libunwind
+uses a platform\-string of
+ia64
+and, at least in theory, should be able to support all
+operating systems adhering to the processor\-specific ABI defined for
+the Itanium Processor Family. This includes both little\-endian Linux
+and big\-endian HP\-UX. Furthermore, to make it possible for a single
+library to unwind both 32\- and 64\-bit targets, the type
+unw_word_t
+is always defined to be 64 bits wide (independent
+of the natural word\-size of the host). Having said that, the current
+implementation has been tested only with IA\-64 Linux.
+.PP
+When targeting IA\-64, the libunwind
+header file defines the
+macro UNW_TARGET_IA64
+as 1 and the macro UNW_TARGET
+as ``ia64\&'' (without the quotation marks). The former makes it
+possible for platform\-dependent unwind code to use
+conditional\-compilation to select an appropriate implementation. The
+latter is useful for stringification purposes and to construct
+target\-platform\-specific symbols.
+.PP
+One special feature of IA\-64 is the use of NaT bits to support
+speculative execution. Often, NaT bits are thought of as the ``65\-th
+bit\&'' of a general register. However, to make everything fit into
+64\-bit wide unw_word_t
+values, libunwind
+treats the
+NaT\-bits like separate boolean registers, whose 64\-bit value is either
+TRUE (non\-zero) or FALSE (zero).
+.PP
+.SH MACHINE\-STATE
+
+.PP
+The machine\-state (set of registers) that is accessible through
+libunwind
+depends on the type of stack frame that a cursor
+points to. For normal frames, all ``preserved\&'' (callee\-saved)
+registers are accessible. For signal\-trampoline frames, all registers
+(including ``scratch\&'' (caller\-saved) registers) are accessible. Most
+applications do not have to worry a\-priori about which registers are
+accessible when. In case of doubt, it is always safe to \fItry\fP
+to
+access a register (via unw_get_reg()
+or
+unw_get_fpreg())
+and if the register isn\&'t accessible, the
+call will fail with a return\-value of \-UNW_EBADREG\&.
+.PP
+As a special exception to the above general rule, scratch registers
+r15\-r18
+are always accessible, even in normal
+frames. This makes it possible to pass arguments, e.g., to exception
+handlers.
+.PP
+For a detailed description of the IA\-64 register usage convention,
+please see the ``Itanium Software Conventions and Runtime Architecture
+Guide\&'', available at:
+.ce 100
+\fBhttp://www.intel.com/design/itanium/downloads/245358.htm\fP
+.ce 0
+
+.PP
+.SH REGISTER NAMES
+
+.PP
+The IA\-64\-version of libunwind
+defines three kinds of register
+name macros: frame\-register macros, normal register macros, and
+convenience macros. Below, we describe each kind in turn:
+.PP
+.SS FRAME\-REGISTER MACROS
+.PP
+Frame\-registers are special (pseudo) registers because they always
+have a valid value, even though sometimes they do not get saved
+explicitly (e.g., if a memory stack frame is 16 bytes in size, the
+previous stack\-pointer value can be calculated simply as
+sp+16,
+so there is no need to save the stack\-pointer
+explicitly). Moreover, the set of frame register values uniquely
+identifies a stack frame. The IA\-64 architecture defines two stacks
+(a memory and a register stack). Including the instruction\-pointer
+(IP), this means there are three frame registers:
+.TP
+UNW_IA64_IP:
+ Contains the instruction pointer (IP, or
+``program counter\&'') of the current stack frame. Given this value,
+the remaining machine\-state corresponds to the register\-values that
+were present in the CPU when it was just about to execute the
+instruction pointed to by UNW_IA64_IP\&.
+Bits 0 and 1 of
+this frame\-register encode the slot number of the instruction.
+\fBNote:\fP
+Due to the way the call instruction works on IA\-64,
+the slot number is usually zero, but can be non\-zero, e.g., in the
+stack\-frame of a signal\-handler trampoline.
+.TP
+UNW_IA64_SP:
+ Contains the (memory) stack\-pointer
+value (SP).
+.TP
+UNW_IA64_BSP:
+ Contains the register backing\-store
+pointer (BSP). \fBNote:\fP
+the value in this register is equal
+to the contents of register ar.bsp
+at the time the
+instruction at UNW_IA64_IP
+was about to begin execution.
+.PP
+.SS NORMAL REGISTER MACROS
+.PP
+The following normal register name macros are available:
+.TP
+UNW_IA64_GR:
+ The base\-index for general (integer)
+registers. Add an index in the range from 0..127 to get a
+particular general register. For example, to access r4,
+the index UNW_IA64_GR+4
+should be used.
+Registers r0
+and r1
+(gp)
+are read\-only,
+and any attempt to write them will result in an error
+(\-UNW_EREADONLYREG).
+Even though r1
+is
+read\-only, libunwind
+will automatically adjust its value if
+the instruction\-pointer (UNW_IA64_IP)
+is modified. For
+example, if UNW_IA64_IP
+is set to a value inside a
+function func(),
+then reading
+UNW_IA64_GR+1
+will return the global\-pointer
+value for this function.
+.TP
+UNW_IA64_NAT:
+ The base\-index for the NaT bits of the
+general (integer) registers. A non\-zero value in these registers
+corresponds to a set NaT\-bit. Add an index in the range from 0..127
+to get a particular NaT\-bit register. For example, to access the
+NaT bit of r4,
+the index UNW_IA64_NAT+4
+should be used.
+.TP
+UNW_IA64_FR:
+ The base\-index for floating\-point
+registers. Add an index in the range from 0..127 to get a
+particular floating\-point register. For example, to access
+f2,
+the index UNW_IA64_FR+2
+should be
+used. Registers f0
+and f1
+are read\-only, and any
+attempt to write to indices UNW_IA64_FR+0
+or
+UNW_IA64_FR+1
+will result in an error
+(\-UNW_EREADONLYREG).
+.TP
+UNW_IA64_AR:
+ The base\-index for application
+registers. Add an index in the range from 0..127 to get a
+particular application register. For example, to access
+ar40,
+the index UNW_IA64_AR+40
+should be
+used. The IA\-64 architecture defines several application registers
+as ``reserved for future use\&''\&. Attempting to access such registers
+results in an error (\-UNW_EBADREG).
+.TP
+UNW_IA64_BR:
+ The base\-index for branch registers.
+Add an index in the range from 0..7 to get a particular branch
+register. For example, to access b6,
+the index
+UNW_IA64_BR+6
+should be used.
+.TP
+UNW_IA64_PR:
+ Contains the set of predicate registers.
+This 64\-bit wide register contains registers p0
+through
+p63
+in the ``broad\-side\&'' format. Just like with the
+``move predicates\&'' instruction, the registers are mapped as if
+CFM.rrb.pr
+were set to 0. Thus, in general the value of
+predicate register pN
+with N>=16 can be found
+in bit 16 + ((N\-16)+CFM.rrb.pr) % 48\&.
+.TP
+UNW_IA64_CFM:
+ Contains the current\-frame\-mask
+register.
+.PP
+.SS CONVENIENCE MACROS

+Convenience macros are simply aliases for certain frequently used

+UNW_IA64_GP:

+UNW_IA64_TP:

+.TP
+UNW_IA64_AR_BSP:

+\section{Introduction}
+
+The IA-64 version of \Prog{libunwind} uses a platform-string of
+\texttt{ia64} and, at least in theory, should be able to support all
+operating systems adhering to the processor-specific ABI defined for
+the Itanium Processor Family. This includes both little-endian Linux
+and big-endian HP-UX. Furthermore, to make it possible for a single
+library to unwind both 32- and 64-bit targets, the type
+\Type{unw\_word\_t} is always defined to be 64 bits wide (independent
+of the natural word-size of the host). Having said that, the current
+implementation has been tested only with IA-64 Linux.
+
+When targeting IA-64, the \Prog{libunwind} header file defines the
+macro \Const{UNW\_TARGET\_IA64} as 1 and the macro \Const{UNW\_TARGET}
+as ``ia64'' (without the quotation marks). The former makes it
+possible for platform-dependent unwind code to use
+conditional-compilation to select an appropriate implementation. The
+latter is useful for stringification purposes and to construct
+target-platform-specific symbols.
+
+One special feature of IA-64 is the use of NaT bits to support
+speculative execution. Often, NaT bits are thought of as the ``65-th
+bit'' of a general register. However, to make everything fit into
+64-bit wide \Type{unw\_word\_t} values, \Prog{libunwind} treats the
+NaT-bits like separate boolean registers, whose 64-bit value is either
+TRUE (non-zero) or FALSE (zero).
+
+
+\section{Machine-State}
+
+The machine-state (set of registers) that is accessible through
+\Prog{libunwind} depends on the type of stack frame that a cursor
+points to. For normal frames, all ``preserved'' (callee-saved)
+registers are accessible. For signal-trampoline frames, all registers
+(including ``scratch'' (caller-saved) registers) are accessible. Most
+applications do not have to worry a-priori about which registers are
+accessible when. In case of doubt, it is always safe to \emph{try} to
+access a register (via \Func{unw\_get\_reg}() or
+\Func{unw\_get\_fpreg}()) and if the register isn't accessible, the
+call will fail with a return-value of \texttt{-}\Const{UNW\_EBADREG}.
+
+As a special exception to the above general rule, scratch registers
+\texttt{r15}-\texttt{r18} are always accessible, even in normal
+frames. This makes it possible to pass arguments, e.g., to exception
+handlers.
+
+For a detailed description of the IA-64 register usage convention,
+please see the ``Itanium Software Conventions and Runtime Architecture
+Guide'', available at:
+\begin{center}
+ \URL{http://www.intel.com/design/itanium/downloads/245358.htm}
+\end{center}
+
+
+\section{Register Names}
+
+The IA-64-version of \Prog{libunwind} defines three kinds of register
+name macros: frame-register macros, normal register macros, and
+convenience macros. Below, we describe each kind in turn:
+
+
+\subsection{Frame-register Macros}
+
+Frame-registers are special (pseudo) registers because they always
+have a valid value, even though sometimes they do not get saved
+explicitly (e.g., if a memory stack frame is 16 bytes in size, the
+previous stack-pointer value can be calculated simply as
+\texttt{sp+16}, so there is no need to save the stack-pointer
+explicitly). Moreover, the set of frame register values uniquely
+identifies a stack frame. The IA-64 architecture defines two stacks
+(a memory and a register stack). Including the instruction-pointer
+(IP), this means there are three frame registers:
+\begin{Description}
+\item[\Const{UNW\_IA64\_IP}:] Contains the instruction pointer (IP, or
+ ``program counter'') of the current stack frame. Given this value,
+ the remaining machine-state corresponds to the register-values that
+ were present in the CPU when it was just about to execute the
+ instruction pointed to by \Const{UNW\_IA64\_IP}. Bits 0 and 1 of
+ this frame-register encode the slot number of the instruction.
+ \textbf{Note:} Due to the way the call instruction works on IA-64,
+ the slot number is usually zero, but can be non-zero, e.g., in the
+ stack-frame of a signal-handler trampoline.
+\item[\Const{UNW\_IA64\_SP}:] Contains the (memory) stack-pointer
+ value (SP).
+\item[\Const{UNW\_IA64\_BSP}:] Contains the register backing-store
+ pointer (BSP). \textbf{Note:} the value in this register is equal
+ to the contents of register \texttt{ar.bsp} at the time the
+ instruction at \Const{UNW\_IA64\_IP} was about to begin execution.
+\end{Description}
+
+
+\subsection{Normal Register Macros}
+
+The following normal register name macros are available:
+\begin{Description}
+\item[\Const{UNW\_IA64\_GR}:] The base-index for general (integer)
+ registers. Add an index in the range from 0..127 to get a
+ particular general register. For example, to access \texttt{r4},
+ the index \Const{UNW\_IA64\_GR}\texttt{+4} should be used.
+ Registers \texttt{r0} and \texttt{r1} (\texttt{gp}) are read-only,
+ and any attempt to write them will result in an error
+ (\texttt{-}\Const{UNW\_EREADONLYREG}). Even though \texttt{r1} is
+ read-only, \Prog{libunwind} will automatically adjust its value if
+ the instruction-pointer (\Const{UNW\_IA64\_IP}) is modified. For
+ example, if \Const{UNW\_IA64\_IP} is set to a value inside a
+ function \Func{func}(), then reading
+ \Const{UNW\_IA64\_GR}\texttt{+1} will return the global-pointer
+ value for this function.
+\item[\Const{UNW\_IA64\_NAT}:] The base-index for the NaT bits of the
+ general (integer) registers. A non-zero value in these registers
+ corresponds to a set NaT-bit. Add an index in the range from 0..127
+ to get a particular NaT-bit register. For example, to access the
+ NaT bit of \texttt{r4}, the index \Const{UNW\_IA64\_NAT}\texttt{+4}
+ should be used.
+\item[\Const{UNW\_IA64\_FR}:] The base-index for floating-point
+ registers. Add an index in the range from 0..127 to get a
+ particular floating-point register. For example, to access
+ \texttt{f2}, the index \Const{UNW\_IA64\_FR}\texttt{+2} should be
+ used. Registers \texttt{f0} and \texttt{f1} are read-only, and any
+ attempt to write to indices \Const{UNW\_IA64\_FR}\texttt{+0} or
+ \Const{UNW\_IA64\_FR}\texttt{+1} will result in an error
+ (\texttt{-}\Const{UNW\_EREADONLYREG}).
+\item[\Const{UNW\_IA64\_AR}:] The base-index for application
+ registers. Add an index in the range from 0..127 to get a
+ particular application register. For example, to access
+ \texttt{ar40}, the index \Const{UNW\_IA64\_AR}\texttt{+40} should be
+ used. The IA-64 architecture defines several application registers
+ as ``reserved for future use''. Attempting to access such registers
+ results in an error (\texttt{-}\Const{UNW\_EBADREG}).
+\item[\Const{UNW\_IA64\_BR}:] The base-index for branch registers.
+ Add an index in the range from 0..7 to get a particular branch
+ register. For example, to access \texttt{b6}, the index
+ \Const{UNW\_IA64\_BR}\texttt{+6} should be used.
+\item[\Const{UNW\_IA64\_PR}:] Contains the set of predicate registers.
+ This 64-bit wide register contains registers \texttt{p0} through
+ \texttt{p63} in the ``broad-side'' format. Just like with the
+ ``move predicates'' instruction, the registers are mapped as if
+ \texttt{CFM.rrb.pr} were set to 0. Thus, in general the value of
+ predicate register \texttt{p}$N$ with $N$>=16 can be found
+ in bit \texttt{16 + (($N$-16)+CFM.rrb.pr) \% 48}.
+\item[\Const{UNW\_IA64\_CFM}:] Contains the current-frame-mask
+ register.
+\end{Description}
+
+
+\subsection{Convenience Macros}
+
+Convenience macros are simply aliases for certain frequently used
+registers:
+\begin{Description}
+\item[\Const{UNW\_IA64\_GP}:] Alias for \Const{UNW\_IA64\_GR}\texttt{+1},
+ the global-pointer register.
+\item[\Const{UNW\_IA64\_TP}:] Alias for \Const{UNW\_IA64\_GR}\texttt{+13},
+ the thread-pointer register.
+\item[\Const{UNW\_IA64\_AR\_RSC}:] Alias for \Const{UNW\_IA64\_GR}\texttt{+16},
+ the register-stack configuration register.
+\item[\Const{UNW\_IA64\_AR\_BSP}:] Alias for
+ \Const{UNW\_IA64\_GR}\texttt{+17}. This register index accesses the
+ value of register \texttt{ar.bsp} as of the time it was last saved
+ explicitly. This is rarely what you want. Normally, you'll want to
+ use \Const{UNW\_IA64\_BSP} instead.
+\item[\Const{UNW\_IA64\_AR\_BSPSTORE}:] Alias for \Const{UNW\_IA64\_GR}\texttt{+18},
+ the register-backing store write pointer.
+\item[\Const{UNW\_IA64\_AR\_RNAT}:] Alias for \Const{UNW\_IA64\_GR}\texttt{+19},
+ the register-backing store NaT-collection register.
+\item[\Const{UNW\_IA64\_AR\_CCV}:] Alias for \Const{UNW\_IA64\_GR}\texttt{+32},
+ the compare-and-swap value register.
+\item[\Const{UNW\_IA64\_AR\_CSD}:] Alias for \Const{UNW\_IA64\_GR}\texttt{+25},
+ the compare-and-swap-data register (used by 16-byte atomic operations).
+\item[\Const{UNW\_IA64\_AR\_UNAT}:] Alias for \Const{UNW\_IA64\_GR}\texttt{+36},
+ the user NaT-collection register.
+\item[\Const{UNW\_IA64\_AR\_FPSR}:] Alias for \Const{UNW\_IA64\_GR}\texttt{+40},
+ the floating-point status (and control) register.
+\item[\Const{UNW\_IA64\_AR\_PFS}:] Alias for \Const{UNW\_IA64\_GR}\texttt{+64},
+ the previous frame-state register.
+\item[\Const{UNW\_IA64\_AR\_LC}:] Alias for \Const{UNW\_IA64\_GR}\texttt{+65}

+.SH DESCRIPTION
+
+.PP
+The ptrace(2)
+system\-call makes it possible for a process to
+gain access to the machine\-state and virtual memory of \fIanother\fP
+process. With the right set of call\-back routines, it is therefore
+possible to hook up libunwind
+to another process via
+ptrace(2).
+While it\&'s not very difficult to do so directly,
+libunwind
+further facilitates this task by providing
+ready\-to\-use callbacks for this purpose. The routines and variables
+implementing this facility use a name\-prefix of _UPT,
+which is
+stands for ``unwind\-via\-ptrace\&''\&.
+.PP
+An application that wants to use the _UPT\-facility
+first needs
+to create a new libunwind
+address\-space that represents the
+target process. This is done by calling
+unw_create_addr_space().
+In many cases, the application
+will simply want to pass the address of _UPT_accessors
+as the
+first argument to this routine. Doing so will ensure that
+libunwind
+will be able to properly unwind the target process.
+However, in special circumstances, an application may prefer to use
+only portions of the _UPT\-facility.
+For this reason, the
+individual callback routines (_UPT_find_proc_info(),
+_UPT_put_unwind_info(),
+etc.) are also available for direct
+use. Of course, the addresses of these routines could also be picked
+up from _UPT_accessors,
+but doing so would prevent static
+initialization. Also, when using _UPT_accessors,
+\fIall\fP
+the callback routines will be linked into the application, even if
+they are never actually called.
+.PP
+Next, the application can turn on ptrace\-mode on the target process,
+either by forking a new process, invoking PTRACE_TRACEME,
+and
+then starting the target program (via execve(2)),
+or by
+directly attaching to an already running process (via
+PTRACE_ATTACH).
+Either way, once the process\-ID (pid) of the
+target process is known, a _UPT\-info\-structure
+can be created
+by calling _UPT_create(),
+passing the pid of the target process
+as the only argument. The returned void\-pointer then needs to be
+passed as the ``argument\&'' pointer (third argument) to
+unw_init_remote().
+.PP
+The _UPT_resume()
+routine can be used to resume execution of
+the target process. It simply invokes ptrace(2)
+with a command
+value of PTRACE_CONT\&.
+.PP
+When the application is done using libunwind
+on the target
+process, _UPT_destroy()
+needs to be called, passing it the
+void\-pointer that was returned by the corresponding call to
+_UPT_create().
+This ensures that all memory and other
+resources are freed up.
+.PP
+.SH AVAILABILITY
+
+.PP
+Since ptrace(2)
+works within a single machine only, the
+_UPT\-facility
+by definition is not available in
+libunwind\-versions
+configured for cross\-unwinding.
+.PP
+.SH THREAD SAFETY
+
+.PP
+The _UPT\-facility
+assumes that a single _UPT\-info
+structure is never shared between threads. Because of this, no
+explicit locking is used. As long as only one thread uses
+a _UPT\-info
+structure at any given time, this facility
+is thread\-safe.
+.PP
+.SH RETURN VALUE
+
+.PP
+_UPT_create()
+may return a NULL
+pointer if it fails
+to create the _UPT\-info\-structure
+for any reason. For the
+current implementation, the only reason this call may fail is when the
+system is out of memory.

+\section{Description}
+
+The \Func{ptrace}(2) system-call makes it possible for a process to
+gain access to the machine-state and virtual memory of \emph{another}
+process. With the right set of call-back routines, it is therefore
+possible to hook up \Prog{libunwind} to another process via
+\Func{ptrace}(2). While it's not very difficult to do so directly,
+\Prog{libunwind} further facilitates this task by providing
+ready-to-use callbacks for this purpose. The routines and variables
+implementing this facility use a name-prefix of \Func{\_UPT}, which is
+stands for ``unwind-via-ptrace''.
+
+An application that wants to use the \Func{\_UPT}-facility first needs
+to create a new \Prog{libunwind} address-space that represents the
+target process. This is done by calling
+\Func{unw\_create\_addr\_space}(). In many cases, the application
+will simply want to pass the address of \Var{\_UPT\_accessors} as the
+first argument to this routine. Doing so will ensure that
+\Prog{libunwind} will be able to properly unwind the target process.
+However, in special circumstances, an application may prefer to use
+only portions of the \Prog{\_UPT}-facility. For this reason, the
+individual callback routines (\Func{\_UPT\_find\_proc\_info}(),
+\Func{\_UPT\_put\_unwind\_info}(), etc.) are also available for direct
+use. Of course, the addresses of these routines could also be picked
+up from \Var{\_UPT\_accessors}, but doing so would prevent static
+initialization. Also, when using \Var{\_UPT\_accessors}, \emph{all}
+the callback routines will be linked into the application, even if
+they are never actually called.
+
+Next, the application can turn on ptrace-mode on the target process,
+either by forking a new process, invoking \Const{PTRACE\_TRACEME}, and
+then starting the target program (via \Func{execve}(2)), or by
+directly attaching to an already running process (via
+\Const{PTRACE\_ATTACH}). Either way, once the process-ID (pid) of the
+target process is known, a \Prog{\_UPT}-info-structure can be created
+by calling \Func{\_UPT\_create}(), passing the pid of the target process
+as the only argument. The returned void-pointer then needs to be
+passed as the ``argument'' pointer (third argument) to
+\Func{unw\_init\_remote}().
+
+The \Func{\_UPT\_resume}() routine can be used to resume execution of
+the target process. It simply invokes \Func{ptrace}(2) with a command
+value of \Const{PTRACE\_CONT}.
+
+When the application is done using \Prog{libunwind} on the target
+process, \Func{\_UPT\_destroy}() needs to be called, passing it the
+void-pointer that was returned by the corresponding call to
+\Func{\_UPT\_create}(). This ensures that all memory and other
+resources are freed up.
+
+\section{Availability}
+
+Since \Func{ptrace}(2) works within a single machine only, the
+\Prog{\_UPT}-facility by definition is not available in
+\Prog{libunwind}-versions configured for cross-unwinding.
+
+\section{Thread Safety}
+
+The \Prog{\_UPT}-facility assumes that a single \Prog{\_UPT}-info
+structure is never shared between threads. Because of this, no
+explicit locking is used. As long as only one thread uses
+a \Prog{\_UPT}-info structure at any given time, this facility
+is thread-safe.
+
+\section{Return Value}
+
+\Func{\_UPT\_create}() may return a \Const{NULL} pointer if it fails
+to create the \Prog{\_UPT}-info-structure for any reason. For the
+current implementation, the only reason this call may fail is when the
+system is out of memory.

+.PP
+.SH LOCAL UNWINDING
+
+.PP
+Libunwind
+is very easy to use when unwinding a stack from
+within a running program. This is called \fIlocal\fP
+unwinding. Say
+you want to unwind the stack while executing in some function
+F().
+In this function, you would call unw_getcontext()
+to get a snapshot of the CPU registers (machine\-state). Then you
+initialize an \fIunwind cursor\fP
+based on this snapshot. This is
+done with a call to unw_init_local().
+The cursor now points
+to the current frame, that is, the stack frame that corresponds to the
+current activation of function F().
+The unwind cursor can then
+be moved ``up\&'' (towards earlier stack frames) by calling
+unw_step().
+By repeatedly calling this routine, you can
+uncover the entire call\-chain that led to the activation of function
+F().
+A positive return value from unw_step()
+indicates
+that there are more frames in the chain, zero indicates that the end
+of the chain has been reached, and any negative value indicates that
+some sort of error has occurred.
+.PP
+While it is not possible to directly move the unwind cursor in the
+``down\&'' direction (towards newer stack frames), this effect can be
+achieved by making copies of an unwind cursor. For example, a program
+that sometimes has to move ``down\&'' by one stack frame could maintain
+two cursor variables: ``curr\&''
+and ``prev\&''\&.
+The former
+would be used as the current cursor and prev
+would be maintained
+as the ``previous frame\&'' cursor by copying the contents of curr
+to prev
+right before calling unw_step().
+With this
+approach, the program could move one step ``down\&'' simply by copying
+back prev
+to curr
+whenever that is necessary. In the most
+extreme case, a program could maintain a separate cursor for each call
+frame and that way it could move up and down the callframe\-chain at
+will.
+.PP
+Given an unwind cursor, it is possible to read and write the CPU
+registers that were preserved for the current stack frame (as
+identified by the cursor). Libunwind
+provides several routines
+for this purpose: unw_get_reg()
+reads an integer (general)
+register, unw_get_fpreg()
+reads a floating\-point register,
+unw_set_reg()
+writes an integer register, and
+unw_set_fpreg()
+writes a floating\-point register. Note that,
+by definition, only the \fIpreserved\fP
+machine state can be accessed
+during an unwind operation. Normally, this state consists of the
+\fIcallee\-saved\fP
+(``preserved\&'') registers. However, in some
+special circumstances (e.g., in a signal handler trampoline), even the
+\fIcaller\-saved\fP
+(``scratch\&'') registers are preserved in the stack
+frame and, in those cases, libunwind
+will grant access to them
+as well. The exact set of registers that can be accessed via the
+cursor depends, of course, on the platform. However, there are two
+registers that can be read on all platforms: the instruction pointer
+(IP), sometimes also known as the ``program counter\&'', and the stack
+pointer (SP). In libunwind,
+these registers are identified by
+the macros UNW_REG_IP
+and UNW_REG_SP,
+respectively.
+.PP
+Besides just moving the unwind cursor and reading/writing saved
+registers, libunwind
+also provides the ability to resume
+execution at an arbitrary stack frame. As you might guess, this is
+useful for implementing non\-local gotos and the exception handling
+needed by some high\-level languages such as Java. Resuming execution
+with a particular stack frame simply requires calling
+unw_resume()
+and passing the cursor identifying the target
+frame as the only argument.
+.PP
+Normally, libunwind
+supports both local and remote unwinding
+(the latter will be explained in the next section). However, if you
+tell libunwind that your program only needs local unwinding, then a
+special implementation can be selected which may run much faster than
+the generic implementation which supports both kinds of unwinding. To
+select this optimized version, simply define the macro
+UNW_LOCAL_ONLY
+before including the headerfile
+<libunwind.h>\&.
+It is perfectly OK for a single program to
+employ both local\-only and generic unwinding. That is, whether or not
+UNW_LOCAL_ONLY
+is defined is a choice that each source\-file
+(compilation\-unit) can make on its own. Independent of the setting(s)
+of UNW_LOCAL_ONLY,
+you\&'ll always link the same library into
+the program (normally \fB\-l\fPunwind).
+Furthermore, the
+portion of libunwind
+that manages unwind\-info for dynamically
+generated code is not affected by the setting of
+UNW_LOCAL_ONLY\&.
+.PP
+If we put all of the above together, here is how we could use
+libunwind
+to write a function ``show_backtrace()\&''
+which prints a classic stack trace:
+.PP
+.Vb
+#define UNW_LOCAL_ONLY
+#include <libunwind.h>
+
+void show_backtrace (void) {
+ unw_cursor_t cursor; unw_context_t uc;
+ unw_word_t ip, sp;
+
+ unw_getcontext(&uc);
+ unw_init_local(&cursor, &uc);
+ while (unw_step(&cursor) > 0) {
+ unw_get_reg(&cursor, UNW_REG_IP, &ip);
+ unw_get_reg(&cursor, UNW_REG_SP, &sp);
+ printf ("ip = %lx, sp = %lx\\n", (long) ip, (long) sp);
+ }
+}
+.Ve
+.PP
+.SH REMOTE UNWINDING
+
+.PP
+Libunwind
+can also be used to unwind a stack in a ``remote\&''
+process. Here, ``remote\&'' may mean another process on the same
+machine or even a process on a completely different machine from the
+one that is running libunwind\&.
+Remote unwinding is typically
+used by debuggers and instruction\-set simulators, for example.
+.PP
+Before you can unwind a remote process, you need to create a new
+address\-space object for that process. This is achieved with the
+unw_create_addr_space()
+routine. The routine takes two
+arguments: a pointer to a set of \fIaccessor\fP
+routines and an
+integer that specifies the byte\-order of the target process. The
+accessor routines provide libunwind
+with the means to
+communicate with the remote process. In particular, there are
+callbacks to read and write the process\&'s memory, its registers, and
+to access unwind information which may be needed by libunwind\&.
+.PP
+With the address space created, unwinding can be initiated by a call
+to unw_init_remote().
+This routine is very similar to
+unw_init_local(),
+except that it takes an address\-space
+object and an opaque pointer as arguments. The routine uses these
+arguments to fetch the initial machine state. Libunwind
+never
+uses the opaque pointer on its own, but instead just passes it on to
+the accessor (callback) routines. Typically, this pointer is used to
+select, e.g., the thread within a process that is to be unwound.
+.PP
+Once a cursor has been initialized with unw_init_remote(),
+unwinding works exactly like in the local case. That is, you can use
+unw_step()
+to move ``up\&'' in the call\-chain, read and write
+registers, or resume execution at a particular stack frame by calling
+unw_resume\&.
+.PP
+.SH CROSS\-PLATFORM AND MULTI\-PLATFORM UNWINDING
+
+.PP
+Libunwind
+has been designed to enable unwinding across
+platforms (architectures). Indeed, a single program can use
+libunwind
+to unwind an arbitrary number of target platforms,
+all at the same time!
+.PP
+We call the machine that is running libunwind
+the \fIhost\fP
+and the machine that is running the process being unwound the
+\fItarget\fP\&.
+If the host and the target platform are the same, we
+call it \fInative\fP
+unwinding. If they differ, we call it
+\fIcross\-platform\fP
+unwinding.
+.PP
+The principle behind supporting native, cross\-platform, and
+multi\-platform unwinding is very simple: for native unwinding, a
+program includes <libunwind.h>
+and uses the linker switch
+\fB\-l\fPunwind\&.
+For cross\-platform unwinding, a program
+includes <libunwind\-PLAT\&.h>
+and uses the linker
+switch \fB\-l\fPunwind\-PLAT,
+where PLAT
+is the name
+of the target platform (e.g., ia64
+for IA\-64, hppa\-elf
+for ELF\-based HP PA\-RISC, or x86
+for 80386). Multi\-platform
+unwinding works exactly like cross\-platform unwinding, the only
+limitation is that a single source file (compilation unit) can include
+at most one libunwind
+header file. In other words, the
+platform\-specific support for each supported target needs to be
+isolated in separate source files\-\-\-a limitation that shouldn\&'t be an
+issue in practice.
+.PP
+Note that, by definition, local unwinding is possible only for the
+native case. Attempting to call, e.g., unw_local_init()
+when
+targeting a cross\-platform will result in a link\-time error
+(unresolved references).
+.PP
+.SH THREAD\- AND SIGNAL\-SAFETY
+
+.PP
+All libunwind
+routines are thread\-safe. What this means is
+that multiple threads may use libunwind
+simulatenously.
+However, any given cursor may be accessed by only one thread at
+any given time.
+.PP
+To ensure thread\-safety, some libunwind
+routines may have to
+use locking. Such routines \fImust not\fP
+be called from signal
+handlers (directly or indirectly) and are therefore \fInot\fP
+signal\-safe. The manual page for each libunwind
+routine
+identifies whether or not it is signal\-safe, but as a general rule,
+any routine that may be needed for \fIlocal\fP
+unwinding is
+signal\-safe (e.g., unw_step()
+for local unwinding is
+signal\-safe). For remote\-unwinding, \fInone\fP
+of the
+libunwind
+routines are guaranteed to be signal\-safe.
+.PP
+.SH UNWINDING THROUGH DYNAMICALLY GENERATED CODE
+
+.PP
+Libunwind
+provides the routines _U_dyn_register()
+and
+_U_dyn_cancel()
+to register/cancel the information required to
+unwind through code that has been generated at runtime (e.g., by a
+just\-in\-time (JIT) compiler). It is important to register the
+information for \fIall\fP
+dynamically generated code because
+otherwise, a debugger may not be able to function properly or
+high\-level language exception handling may not work as expected.
+.PP
+The interface for registering and canceling dynamic unwind info has
+been designed for maximum efficiency, so as to minimize the
+performance impact on JIT\-compilers. In particular, both routines are

+.SH CACHING OF UNWIND INFO
+
+.PP
+To speed up execution, libunwind
+may aggressively cache the
+information it needs to perform unwinding. If a process changes
+during its lifetime, this creates a risk of libunwind
+using
+stale data. For example, this would happen if libunwind
+were
+to cache information about a shared library which later on gets
+unloaded (e.g., via \fIdlclose\fP(3)).
+.PP
+To prevent the risk of using stale data, libunwind
+provides two
+facilities: first, it is possible to flush the cached information
+associated with a specific address range in the target process (or the
+entire address space, if desired). This functionality is provided by
+unw_flush_cache().
+The second facility is provided by
+unw_set_caching_policy(),
+which lets a program
+select the exact caching policy in use for a given address\-space
+object. In particular, by selecting the policy
+UNW_CACHE_NONE,
+it is possible to turn off caching
+completely, therefore eliminating the risk of stale data alltogether
+(at the cost of slower execution). By default, caching is enabled for
+local unwinding only.

+\section{Local Unwinding}
+
+\Prog{Libunwind} is very easy to use when unwinding a stack from
+within a running program. This is called \emph{local} unwinding. Say
+you want to unwind the stack while executing in some function
+\Func{F}(). In this function, you would call \Func{unw\_getcontext}()
+to get a snapshot of the CPU registers (machine-state). Then you
+initialize an \emph{unwind~cursor} based on this snapshot. This is
+done with a call to \Func{unw\_init\_local}(). The cursor now points
+to the current frame, that is, the stack frame that corresponds to the
+current activation of function \Func{F}(). The unwind cursor can then
+be moved ``up'' (towards earlier stack frames) by calling
+\Func{unw\_step}(). By repeatedly calling this routine, you can
+uncover the entire call-chain that led to the activation of function
+\Func{F}(). A positive return value from \Func{unw\_step}() indicates
+that there are more frames in the chain, zero indicates that the end
+of the chain has been reached, and any negative value indicates that
+some sort of error has occurred.
+
+While it is not possible to directly move the unwind cursor in the
+``down'' direction (towards newer stack frames), this effect can be
+achieved by making copies of an unwind cursor. For example, a program
+that sometimes has to move ``down'' by one stack frame could maintain
+two cursor variables: ``\Var{curr}'' and ``\Var{prev}''. The former
+would be used as the current cursor and \Var{prev} would be maintained
+as the ``previous frame'' cursor by copying the contents of \Var{curr}
+to \Var{prev} right before calling \Func{unw\_step}(). With this
+approach, the program could move one step ``down'' simply by copying
+back \Var{prev} to \Var{curr} whenever that is necessary. In the most
+extreme case, a program could maintain a separate cursor for each call
+frame and that way it could move up and down the callframe-chain at
+will.
+
+Given an unwind cursor, it is possible to read and write the CPU
+registers that were preserved for the current stack frame (as
+identified by the cursor). \Prog{Libunwind} provides several routines
+for this purpose: \Func{unw\_get\_reg}() reads an integer (general)
+register, \Func{unw\_get\_fpreg}() reads a floating-point register,
+\Func{unw\_set\_reg}() writes an integer register, and
+\Func{unw\_set\_fpreg}() writes a floating-point register. Note that,
+by definition, only the \emph{preserved} machine state can be accessed
+during an unwind operation. Normally, this state consists of the
+\emph{callee-saved} (``preserved'') registers. However, in some
+special circumstances (e.g., in a signal handler trampoline), even the
+\emph{caller-saved} (``scratch'') registers are preserved in the stack
+frame and, in those cases, \Prog{libunwind} will grant access to them
+as well. The exact set of registers that can be accessed via the
+cursor depends, of course, on the platform. However, there are two
+registers that can be read on all platforms: the instruction pointer
+(IP), sometimes also known as the ``program counter'', and the stack
+pointer (SP). In \Prog{libunwind}, these registers are identified by
+the macros \Const{UNW\_REG\_IP} and \Const{UNW\_REG\_SP},
+respectively.
+
+Besides just moving the unwind cursor and reading/writing saved
+registers, \Prog{libunwind} also provides the ability to resume
+execution at an arbitrary stack frame. As you might guess, this is
+useful for implementing non-local gotos and the exception handling
+needed by some high-level languages such as Java. Resuming execution
+with a particular stack frame simply requires calling
+\Func{unw\_resume}() and passing the cursor identifying the target
+frame as the only argument.
+
+Normally, \Prog{libunwind} supports both local and remote unwinding
+(the latter will be explained in the next section). However, if you
+tell libunwind that your program only needs local unwinding, then a
+special implementation can be selected which may run much faster than
+the generic implementation which supports both kinds of unwinding. To
+select this optimized version, simply define the macro
+\Const{UNW\_LOCAL\_ONLY} before including the headerfile
+\File{$<$libunwind.h$>$}. It is perfectly OK for a single program to
+employ both local-only and generic unwinding. That is, whether or not
+\Const{UNW\_LOCAL\_ONLY} is defined is a choice that each source-file
+(compilation-unit) can make on its own. Independent of the setting(s)
+of \Const{UNW\_LOCAL\_ONLY}, you'll always link the same library into
+the program (normally \Opt{-l}\File{unwind}). Furthermore, the
+portion of \Prog{libunwind} that manages unwind-info for dynamically
+generated code is not affected by the setting of
+\Const{UNW\_LOCAL\_ONLY}.
+
+If we put all of the above together, here is how we could use
+\Prog{libunwind} to write a function ``\Func{show\_backtrace}()''
+which prints a classic stack trace:
+
+\begin{verbatim}
+#define UNW_LOCAL_ONLY
+#include <libunwind.h>
+
+void show_backtrace (void) {
+ unw_cursor_t cursor; unw_context_t uc;
+ unw_word_t ip, sp;
+
+ unw_getcontext(&uc);
+ unw_init_local(&cursor, &uc);
+ while (unw_step(&cursor) > 0) {
+ unw_get_reg(&cursor, UNW_REG_IP, &ip);
+ unw_get_reg(&cursor, UNW_REG_SP, &sp);
+ printf ("ip = %lx, sp = %lx\n", (long) ip, (long) sp);
+ }
+}
+\end{verbatim}
+
+
+\section{Remote Unwinding}
+
+\Prog{Libunwind} can also be used to unwind a stack in a ``remote''
+process. Here, ``remote'' may mean another process on the same
+machine or even a process on a completely different machine from the
+one that is running \Prog{libunwind}. Remote unwinding is typically
+used by debuggers and instruction-set simulators, for example.
+
+Before you can unwind a remote process, you need to create a new
+address-space object for that process. This is achieved with the
+\Func{unw\_create\_addr\_space}() routine. The routine takes two
+arguments: a pointer to a set of \emph{accessor} routines and an
+integer that specifies the byte-order of the target process. The
+accessor routines provide \Func{libunwind} with the means to
+communicate with the remote process. In particular, there are
+callbacks to read and write the process's memory, its registers, and
+to access unwind information which may be needed by \Func{libunwind}.
+
+With the address space created, unwinding can be initiated by a call
+to \Func{unw\_init\_remote}(). This routine is very similar to
+\Func{unw\_init\_local}(), except that it takes an address-space
+object and an opaque pointer as arguments. The routine uses these
+arguments to fetch the initial machine state. \Prog{Libunwind} never
+uses the opaque pointer on its own, but instead just passes it on to
+the accessor (callback) routines. Typically, this pointer is used to
+select, e.g., the thread within a process that is to be unwound.
+
+Once a cursor has been initialized with \Func{unw\_init\_remote}(),
+unwinding works exactly like in the local case. That is, you can use
+\Func{unw\_step}() to move ``up'' in the call-chain, read and write
+registers, or resume execution at a particular stack frame by calling
+\Func{unw\_resume}.
+
+
+\section{Cross-platform and Multi-platform Unwinding}
+
+\Prog{Libunwind} has been designed to enable unwinding across
+platforms (architectures). Indeed, a single program can use
+\Prog{libunwind} to unwind an arbitrary number of target platforms,
+all at the same time!
+
+We call the machine that is running \Prog{libunwind} the \emph{host}
+and the machine that is running the process being unwound the
+\emph{target}. If the host and the target platform are the same, we
+call it \emph{native} unwinding. If they differ, we call it
+\emph{cross-platform} unwinding.
+
+The principle behind supporting native, cross-platform, and
+multi-platform unwinding is very simple: for native unwinding, a
+program includes \File{$<$libunwind.h$>$} and uses the linker switch
+\Opt{-l}\File{unwind}. For cross-platform unwinding, a program
+includes \File{$<$libunwind-}\Var{PLAT}\File{.h$>$} and uses the linker
+switch \Opt{-l}\File{unwind-}\Var{PLAT}, where \Var{PLAT} is the name
+of the target platform (e.g., \File{ia64} for IA-64, \File{hppa-elf}
+for ELF-based HP PA-RISC, or \File{x86} for 80386). Multi-platform
+unwinding works exactly like cross-platform unwinding, the only
+limitation is that a single source file (compilation unit) can include
+at most one \Prog{libunwind} header file. In other words, the
+platform-specific support for each supported target needs to be
+isolated in separate source files---a limitation that shouldn't be an
+issue in practice.
+
+Note that, by definition, local unwinding is possible only for the
+native case. Attempting to call, e.g., \Func{unw\_local\_init}() when
+targeting a cross-platform will result in a link-time error
+(unresolved references).
+
+
+\section{Thread- and Signal-Safety}
+
+
+All \Prog{libunwind} routines are thread-safe. What this means is
+that multiple threads may use \Prog{libunwind} simulatenously.
+However, any given cursor may be accessed by only one thread at
+any given time.
+
+To ensure thread-safety, some \Prog{libunwind} routines may have to
+use locking. Such routines \emph{must~not} be called from signal
+handlers (directly or indirectly) and are therefore \emph{not}
+signal-safe. The manual page for each \Prog{libunwind} routine
+identifies whether or not it is signal-safe, but as a general rule,
+any routine that may be needed for \emph{local} unwinding is
+signal-safe (e.g., \Func{unw\_step}() for local unwinding is
+signal-safe). For remote-unwinding, \emph{none} of the
+\Prog{libunwind} routines are guaranteed to be signal-safe.
+
+
+\section{Unwinding Through Dynamically Generated Code}
+
+\Func{Libunwind} provides the routines \Func{\_U\_dyn\_register}() and
+\Func{\_U\_dyn\_cancel}() to register/cancel the information required to
+unwind through code that has been generated at runtime (e.g., by a
+just-in-time (JIT) compiler). It is important to register the
+information for \emph{all} dynamically generated code because
+otherwise, a debugger may not be able to function properly or
+high-level language exception handling may not work as expected.
+
+The interface for registering and canceling dynamic unwind info has
+been designed for maximum efficiency, so as to minimize the
+performance impact on JIT-compilers. In particular, both routines are
+guaranteed to execute in ``constant time'' (O(1)) and the
+data-structure encapsulating the dynamic unwind info has been designed
+to facilitate sharing, such that similar procedures can share much of
+the underlying information.
+
+For more information on the \Prog{libunwind} support for dynamically
+generated code, see \SeeAlso{libunwind-dynamic(3)}.
+
+
+\section{Caching of Unwind Info}
+
+To speed up execution, \Prog{libunwind} may aggressively cache the
+information it needs to perform unwinding. If a process changes
+during its lifetime, this creates a risk of \Prog{libunwind} using
+stale data. For example, this would happen if \Prog{libunwind} were
+to cache information about a shared library which later on gets
+unloaded (e.g., via \Cmd{dlclose}{3}).
+
+To prevent the risk of using stale data, \Prog{libunwind} provides two
+facilities: first, it is possible to flush the cached information
+associated with a specific address range in the target process (or the
+entire address space, if desired). This functionality is provided by
+\Func{unw\_flush\_cache}(). The second facility is provided by
+\Func{unw\_set\_caching\_policy}(), which lets a program
+select the exact caching policy in use for a given address-space
+object. In particular, by selecting the policy
+\Const{UNW\_CACHE\_NONE}, it is possible to turn off caching
+completely, therefore eliminating the risk of stale data alltogether
+(at the cost of slower execution). By default, caching is enabled for
+local unwinding only.

+Note that many (but not all) systems provide practically identical function
+called \Func{backtrace}(). The prototype for this function is usually obtained
+by including the \File{$<$execinfo.h$>$} header file -- a prototype for
+\Func{backtrace}() is not provided by \Prog{libunwind}. \Prog{libunwind} weakly
+aliases \Func{backtrace}() to \Func{unw\_backtrace}(), so when a program
+calling \Func{backtrace}() is linked against \Prog{libunwind}, it may end up
+calling \Func{unw\_backtrace}().
+
+\section{Return Value}
+
+The routine returns the number of addresses stored in the array pointed by
+\Var{buffer}. The return value may be zero to indicate that no addresses were
+stored.

+
+.PP
+#include <libunwind.h>

+.PP
+.SH DESCRIPTION
+
+.PP
+The unw_create_addr_space()
+routine creates a new unwind
+address\-space and initializes it based on the call\-back routines
+passed via the ap
+pointer and the specified byteorder\&.
+The call\-back routines are described in detail below. The
+byteorder
+can be set to 0 to request the default byte\-order of
+the unwind target. To request a particular byte\-order,
+byteorder
+can be set to any constant defined by
+<endian.h>\&.
+In particular, __LITTLE_ENDIAN
+would
+request little\-endian byte\-order and __BIG_ENDIAN
+would
+request big\-endian byte\-order. Whether or not a particular byte\-order
+is supported depends on the target platform.
+.PP
+.SH CALL\-BACK ROUTINES
+
+.PP
+Libunwind
+uses a set of call\-back routines to access the
+information it needs to unwind a chain of stack\-frames. These
+routines are specified via the ap
+argument, which points to a
+variable of type unw_accessors_t\&.
+The contents of this
+variable is copied into the newly\-created address space, so the
+variable must remain valid only for the duration of the call to
+unw_create_addr_space().
+.PP
+The first argument to every call\-back routine is an address\-space
+identifier (as)
+and the last argument is an arbitrary,
+application\-specified void\-pointer (arg).
+When invoking a
+call\-back routine, libunwind
+sets the as
+argument to the
+address\-space on whose behalf the invocation is made and the arg
+argument to the value that was specified when
+unw_init_remote(3)
+was called.
+.PP
+The synopsis and a detailed description of every call\-back routine
+follows below.

+.PP
+.SS FIND_PROC_INFO
+.PP
+Libunwind
+invokes the find_proc_info()
+call\-back to
+locate the information need to unwind a particular procedure. The
+ip
+argument is an instruction\-address inside the procedure whose
+information is needed. The pip
+argument is a pointer to the
+variable used to return the desired information. The type of this
+variable is unw_proc_info_t\&.
+See
+unw_get_proc_info(3)
+for details. Argument
+need_unwind_info
+is zero if the call\-back does not need to
+provide values for the following members in the
+unw_proc_info_t
+structure: format,
+unwind_info_size,
+and unwind_info\&.
+If
+need_unwind_info
+is non\-zero, valid values need to be returned
+in these members. Furthermore, the contents of the memory addressed
+by the unwind_info
+member must remain valid until the info is
+released via the put_unwind_info
+call\-back (see below).
+.PP
+On successful completion, the find_proc_info()
+call\-back must
+return zero. Otherwise, the negative value of one of the
+unw_error_t
+error\-codes may be returned. In particular, this
+call\-back may return \-UNW_ESTOPUNWIND
+to signal the end of
+the frame\-chain.
+.PP
+.SS PUT_UNWIND_INFO
+.PP
+Libunwind
+invokes the put_unwind_info()
+call\-back to
+release the resources (such as memory) allocated by a previous call to
+find_proc_info()
+with the need_unwind_info
+argument
+set to a non\-zero value. The pip
+argument has the same value as
+the argument of the same name in the previous matching call to
+find_proc_info().
+Note that libunwind
+does \fInot\fP
+invoke put_unwind_info
+for calls to find_proc_info()
+with a zero need_unwind_info
+argument.
+.PP
+.SS GET_DYN_INFO_LIST_ADDR
+.PP
+Libunwind
+invokes the get_dyn_info_list_addr()
+call\-back to obtain the address of the head of the dynamic unwind\-info
+registration list. The variable stored at the returned address must
+have a type of unw_dyn_info_list_t
+(see
+_U_dyn_register(3)).
+The dliap
+argument is a pointer
+to a variable of type unw_word_t
+which is used to return the
+address of the dynamic unwind\-info registration list. If no dynamic
+unwind\-info registration list exist, the value pointed to by
+dliap
+must be cleared to zero. Libunwind
+will cache the
+value returned by get_dyn_info_list_addr()
+if caching is
+enabled for the given address\-space. The cache can be cleared with a
+call to unw_flush_cache().
+.PP
+On successful completion, the get_dyn_info_list_addr()
+call\-back must return zero. Otherwise, the negative value of one of
+the unw_error_t
+error\-codes may be returned.
+.PP
+.SS ACCESS_MEM
+.PP
+Libunwind
+invokes the access_mem()
+call\-back to read
+from or write to a word of memory in the target address\-space. The
+address of the word to be accessed is passed in argument addr\&.
+To read memory, libunwind
+sets argument write
+to zero and
+valp
+to point to the word that receives the read value. To
+write memory, libunwind
+sets argument write
+to a non\-zero
+value and valp
+to point to the word that contains the value to
+be written. The word that valp
+points to is always in the
+byte\-order of the host\-platform, regardless of the byte\-order of the
+target. In other words, it is the responsibility of the call\-back
+routine to convert between the target\&'s and the host\&'s byte\-order, if
+necessary.
+.PP
+On successful completion, the access_mem()
+call\-back must return zero. Otherwise, the negative value of one of
+the unw_error_t
+error\-codes may be returned.
+.PP
+.SS ACCESS_REG
+.PP
+Libunwind
+invokes the access_reg()
+call\-back to read
+from or write to a scalar (non\-floating\-point) CPU register. The
+index of the register to be accessed is passed in argument
+regnum\&.
+To read a register, libunwind
+sets argument
+write
+to zero and valp
+to point to the word that receives
+the read value. To write a register, libunwind
+sets argument
+write
+to a non\-zero value and valp
+to point to the word
+that contains the value to be written. The word that valp
+points to is always in the byte\-order of the host\-platform, regardless
+of the byte\-order of the target. In other words, it is the
+responsibility of the call\-back routine to convert between the
+target\&'s and the host\&'s byte\-order, if necessary.
+.PP
+On successful completion, the access_reg()
+call\-back must
+return zero. Otherwise, the negative value of one of the
+unw_error_t
+error\-codes may be returned.
+.PP
+.SS ACCESS_FPREG
+.PP
+Libunwind
+invokes the access_fpreg()
+call\-back to read
+from or write to a floating\-point CPU register. The index of the
+register to be accessed is passed in argument regnum\&.
+To read a
+register, libunwind
+sets argument write
+to zero and
+fpvalp
+to point to a variable of type unw_fpreg_t
+that
+receives the read value. To write a register, libunwind
+sets
+argument write
+to a non\-zero value and fpvalp
+to point to
+the variable of type unw_fpreg_t
+that contains the value to
+be written. The word that fpvalp
+points to is always in the
+byte\-order of the host\-platform, regardless of the byte\-order of the
+target. In other words, it is the responsibility of the call\-back
+routine to convert between the target\&'s and the host\&'s byte\-order, if
+necessary.
+.PP
+On successful completion, the access_fpreg()
+call\-back must
+return zero. Otherwise, the negative value of one of the
+unw_error_t
+error\-codes may be returned.
+.PP
+.SS RESUME
+.PP
+Libunwind
+invokes the resume()
+call\-back to resume
+execution in the target address space. Argument cp
+is the
+unwind\-cursor that identifies the stack\-frame in which execution
+should resume. By the time libunwind
+invokes the resume
+call\-back, it has already established the desired machine\- and
+memory\-state via calls to the access_reg(),
+access_fpreg,
+and access_mem()
+call\-backs. Thus, all
+the call\-back needs to do is perform whatever action is needed to
+actually resume execution.
+.PP
+The resume
+call\-back is invoked only in response to a call to
+unw_resume(3),
+so applications which never invoke
+unw_resume(3)
+need not define the resume
+callback.
+.PP
+On successful completion, the resume()
+call\-back must return
+zero. Otherwise, the negative value of one of the
+unw_error_t
+error\-codes may be returned. As a special case,
+when resuming execution in the local address space, the call\-back will
+not return on success.
+.PP
+.SS GET_PROC_NAME
+.PP
+Libunwind
+invokes the get_proc_name()
+call\-back to
+obtain the procedure\-name of a static (not dynamically generated)
+procedure. Argument addr
+is an instruction\-address within the
+procedure whose name is to be obtained. The bufp
+argument is a
+pointer to a character\-buffer used to return the procedure name. The
+size of this buffer is specified in argument buf_len\&.
+The
+returned name must be terminated by a NUL character. If the
+procedure\&'s name is longer than buf_len
+bytes, it must be
+truncated to buf_len\-1
+bytes, with the last byte in the
+buffer set to the NUL character and \-UNW_ENOMEM
+must be
+returned. Argument offp
+is a pointer to a word which is used to
+return the byte\-offset relative to the start of the procedure whose
+name is being returned. For example, if procedure foo()
+starts
+at address 0x40003000, then invoking get_proc_name()
+with
+addr
+set to 0x40003080 should return a value of 0x80 in the word
+pointed to by offp
+(assuming the procedure is at least 0x80
+bytes long).
+.PP
+On successful completion, the get_proc_name()
+call\-back must
+return zero. Otherwise, the negative value of one of the
+unw_error_t
+error\-codes may be returned.
+.PP
+.SH RETURN VALUE
+
+.PP
+On successful completion, unw_create_addr_space()
+returns a
+non\-NULL
+value that represents the newly created
+address\-space. Otherwise, NULL
+is returned.
+.PP
+.SH THREAD AND SIGNAL SAFETY

+\section{Description}
+
+The \Func{unw\_create\_addr\_space}() routine creates a new unwind
+address-space and initializes it based on the call-back routines
+passed via the \Var{ap} pointer and the specified \Var{byteorder}.
+The call-back routines are described in detail below. The
+\Var{byteorder} can be set to 0 to request the default byte-order of
+the unwind target. To request a particular byte-order,
+\Var{byteorder} can be set to any constant defined by
+\File{$<$endian.h$>$}. In particular, \Const{\_\_LITTLE\_ENDIAN} would
+request little-endian byte-order and \Const{\_\_BIG\_ENDIAN} would
+request big-endian byte-order. Whether or not a particular byte-order
+is supported depends on the target platform.
+
+\section{Call-back Routines}
+
+\Prog{Libunwind} uses a set of call-back routines to access the
+information it needs to unwind a chain of stack-frames. These
+routines are specified via the \Var{ap} argument, which points to a
+variable of type \Type{unw\_accessors\_t}. The contents of this
+variable is copied into the newly-created address space, so the
+variable must remain valid only for the duration of the call to
+\Func{unw\_create\_addr\_space}().
+
+The first argument to every call-back routine is an address-space
+identifier (\Var{as}) and the last argument is an arbitrary,
+application-specified void-pointer (\Var{arg}). When invoking a
+call-back routine, \Prog{libunwind} sets the \Var{as} argument to the
+address-space on whose behalf the invocation is made and the \Var{arg}
+argument to the value that was specified when
+\Func{unw\_init\_remote}(3) was called.
+
+The synopsis and a detailed description of every call-back routine
+follows below.

+
+\subsection{find\_proc\_info}
+
+\Prog{Libunwind} invokes the \Func{find\_proc\_info}() call-back to
+locate the information need to unwind a particular procedure. The
+\Var{ip} argument is an instruction-address inside the procedure whose
+information is needed. The \Var{pip} argument is a pointer to the
+variable used to return the desired information. The type of this
+variable is \Type{unw\_proc\_info\_t}. See
+\Func{unw\_get\_proc\_info(3)} for details. Argument
+\Var{need\_unwind\_info} is zero if the call-back does not need to
+provide values for the following members in the
+\Type{unw\_proc\_info\_t} structure: \Var{format},
+\Var{unwind\_info\_size}, and \Var{unwind\_info}. If
+\Var{need\_unwind\_info} is non-zero, valid values need to be returned
+in these members. Furthermore, the contents of the memory addressed
+by the \Var{unwind\_info} member must remain valid until the info is
+released via the \Func{put\_unwind\_info} call-back (see below).
+
+On successful completion, the \Func{find\_proc\_info}() call-back must
+return zero. Otherwise, the negative value of one of the
+\Type{unw\_error\_t} error-codes may be returned. In particular, this
+call-back may return -\Const{UNW\_ESTOPUNWIND} to signal the end of
+the frame-chain.
+
+\subsection{put\_unwind\_info}
+
+\Prog{Libunwind} invokes the \Func{put\_unwind\_info}() call-back to
+release the resources (such as memory) allocated by a previous call to
+\Func{find\_proc\_info}() with the \Var{need\_unwind\_info} argument
+set to a non-zero value. The \Var{pip} argument has the same value as
+the argument of the same name in the previous matching call to
+\Func{find\_proc\_info}(). Note that \Prog{libunwind} does \emph{not}
+invoke \Func{put\_unwind\_info} for calls to \Func{find\_proc\_info}()
+with a zero \Var{need\_unwind\_info} argument.
+
+
+\subsection{get\_dyn\_info\_list\_addr}
+
+\Prog{Libunwind} invokes the \Func{get\_dyn\_info\_list\_addr}()
+call-back to obtain the address of the head of the dynamic unwind-info
+registration list. The variable stored at the returned address must
+have a type of \Type{unw\_dyn\_info\_list\_t} (see
+\Func{\_U\_dyn\_register}(3)). The \Var{dliap} argument is a pointer
+to a variable of type \Type{unw\_word\_t} which is used to return the
+address of the dynamic unwind-info registration list. If no dynamic
+unwind-info registration list exist, the value pointed to by
+\Var{dliap} must be cleared to zero. \Prog{Libunwind} will cache the
+value returned by \Func{get\_dyn\_info\_list\_addr}() if caching is
+enabled for the given address-space. The cache can be cleared with a
+call to \Func{unw\_flush\_cache}().
+
+On successful completion, the \Func{get\_dyn\_info\_list\_addr}()
+call-back must return zero. Otherwise, the negative value of one of
+the \Type{unw\_error\_t} error-codes may be returned.
+
+\subsection{access\_mem}
+
+\Prog{Libunwind} invokes the \Func{access\_mem}() call-back to read
+from or write to a word of memory in the target address-space. The
+address of the word to be accessed is passed in argument \Var{addr}.
+To read memory, \Prog{libunwind} sets argument \Var{write} to zero and
+\Var{valp} to point to the word that receives the read value. To
+write memory, \Prog{libunwind} sets argument \Var{write} to a non-zero
+value and \Var{valp} to point to the word that contains the value to
+be written. The word that \Var{valp} points to is always in the
+byte-order of the host-platform, regardless of the byte-order of the
+target. In other words, it is the responsibility of the call-back
+routine to convert between the target's and the host's byte-order, if
+necessary.
+
+On successful completion, the \Func{access\_mem}()
+call-back must return zero. Otherwise, the negative value of one of
+the \Type{unw\_error\_t} error-codes may be returned.
+
+\subsection{access\_reg}
+
+\Prog{Libunwind} invokes the \Func{access\_reg}() call-back to read
+from or write to a scalar (non-floating-point) CPU register. The
+index of the register to be accessed is passed in argument
+\Var{regnum}. To read a register, \Prog{libunwind} sets argument
+\Var{write} to zero and \Var{valp} to point to the word that receives
+the read value. To write a register, \Prog{libunwind} sets argument
+\Var{write} to a non-zero value and \Var{valp} to point to the word
+that contains the value to be written. The word that \Var{valp}
+points to is always in the byte-order of the host-platform, regardless
+of the byte-order of the target. In other words, it is the
+responsibility of the call-back routine to convert between the
+target's and the host's byte-order, if necessary.
+
+On successful completion, the \Func{access\_reg}() call-back must
+return zero. Otherwise, the negative value of one of the
+\Type{unw\_error\_t} error-codes may be returned.
+
+\subsection{access\_fpreg}
+
+\Prog{Libunwind} invokes the \Func{access\_fpreg}() call-back to read
+from or write to a floating-point CPU register. The index of the
+register to be accessed is passed in argument \Var{regnum}. To read a
+register, \Prog{libunwind} sets argument \Var{write} to zero and
+\Var{fpvalp} to point to a variable of type \Type{unw\_fpreg\_t} that
+receives the read value. To write a register, \Prog{libunwind} sets
+argument \Var{write} to a non-zero value and \Var{fpvalp} to point to
+the variable of type \Type{unw\_fpreg\_t} that contains the value to
+be written. The word that \Var{fpvalp} points to is always in the
+byte-order of the host-platform, regardless of the byte-order of the
+target. In other words, it is the responsibility of the call-back
+routine to convert between the target's and the host's byte-order, if
+necessary.
+
+On successful completion, the \Func{access\_fpreg}() call-back must
+return zero. Otherwise, the negative value of one of the
+\Type{unw\_error\_t} error-codes may be returned.
+
+\subsection{resume}
+
+\Prog{Libunwind} invokes the \Func{resume}() call-back to resume
+execution in the target address space. Argument \Var{cp} is the
+unwind-cursor that identifies the stack-frame in which execution
+should resume. By the time \Prog{libunwind} invokes the \Func{resume}
+call-back, it has already established the desired machine- and
+memory-state via calls to the \Func{access\_reg}(),
+\Func{access\_fpreg}, and \Func{access\_mem}() call-backs. Thus, all
+the call-back needs to do is perform whatever action is needed to
+actually resume execution.
+
+The \Func{resume} call-back is invoked only in response to a call to
+\Func{unw\_resume}(3), so applications which never invoke
+\Func{unw\_resume}(3) need not define the \Func{resume} callback.
+
+On successful completion, the \Func{resume}() call-back must return
+zero. Otherwise, the negative value of one of the
+\Type{unw\_error\_t} error-codes may be returned. As a special case,
+when resuming execution in the local address space, the call-back will
+not return on success.
+
+\subsection{get\_proc\_name}
+
+\Prog{Libunwind} invokes the \Func{get\_proc\_name}() call-back to
+obtain the procedure-name of a static (not dynamically generated)
+procedure. Argument \Var{addr} is an instruction-address within the
+procedure whose name is to be obtained. The \Var{bufp} argument is a
+pointer to a character-buffer used to return the procedure name. The
+size of this buffer is specified in argument \Var{buf\_len}. The
+returned name must be terminated by a NUL character. If the
+procedure's name is longer than \Var{buf\_len} bytes, it must be
+truncated to \Var{buf\_len}\Prog{-1} bytes, with the last byte in the
+buffer set to the NUL character and -\Const{UNW\_ENOMEM} must be
+returned. Argument \Var{offp} is a pointer to a word which is used to
+return the byte-offset relative to the start of the procedure whose
+name is being returned. For example, if procedure \Func{foo}() starts
+at address 0x40003000, then invoking \Func{get\_proc\_name}() with
+\Var{addr} set to 0x40003080 should return a value of 0x80 in the word
+pointed to by \Var{offp} (assuming the procedure is at least 0x80
+bytes long).
+
+On successful completion, the \Func{get\_proc\_name}() call-back must
+return zero. Otherwise, the negative value of one of the
+\Type{unw\_error\_t} error-codes may be returned.
+
+
+\section{Return Value}
+
+On successful completion, \Func{unw\_create\_addr\_space}() returns a
+non-\Const{NULL} value that represents the newly created
+address-space. Otherwise, \Const{NULL} is returned.
+
+\section{Thread and Signal Safety}
+
+\Func{unw\_create\_addr\_space}() is thread-safe but \emph{not}
+safe to use from a signal handler.

+ (e.g., due to lack of unwind information), the \Var{start\_ip}

+\item[\Type{unw\_word\_t} \Var{lsda}] The address of the

+even if it is not part of the current call\-chain. However, since it
+is more flexible, it also tends to run slower (and often much slower)
+than unw_get_proc_info().
+.PP
+The routine expects the followins arguments: as

+For a look\-up in the local address\-space,

+Argument ip

+info should be looked up and pip
+is a pointer to a structure of

+which is used to return the info.
+Lastly, arg

+
+.PP
+The unw_get_reg()

+.PP
+The register numbering is target\-dependent and described in separate

+Furthermore, the exact set of accessible registers may depend on the

+frames, it is normally possible to access only the preserved
+(``callee-saved'') registers and frame-related registers (such as the

+
+.PP
+The unw_is_signal_frame()
+routine returns a positive value
+if the current frame identified by cp
+is a signal frame, and a

+frame is a frame that was created in response to a potentially
+asynchronous interruption. For UNIX and UNIX\-like platforms, such
+frames are normally created by the kernel when delivering a signal.
+In a kernel\-environment, a signal frame might, for example, correspond
+to a frame created in response to a device interrupt.
+.PP
+Signal frames are somewhat unusual because the asynchronous nature of

+that are normally treated as scratch (``caller\-saved\&'') registers.
+.PP
+.SH RETURN VALUE
+
+.PP
+On successful completion, unw_is_signal_frame()

+.br
+.PP
+.SH DESCRIPTION
+
+.PP
+The unw_resume()
+routine resumes execution at the stack frame
+identified by cp\&.
+The behavior of this routine differs
+slightly for local and remote unwinding.
+.PP
+For local unwinding, unw_resume()
+restores the machine state
+and then directly resumes execution in the target stack frame. Thus
+unw_resume()
+does not return in this case. Restoring the
+machine state normally involves restoring the ``preserved\&''
+(callee\-saved) registers. However, if execution in any of the stack
+frames younger (more deeply nested) than the one identified by
+cp
+was interrupted by a signal, then unw_resume()
+will
+restore all registers as well as the signal mask. Attempting to call
+unw_resume()
+on a cursor which identifies the stack frame of
+another thread results in undefined behavior (e.g., the program may
+crash).
+.PP
+For remote unwinding, unw_resume()
+installs the machine state
+identified by the cursor by calling the access_reg
+and
+access_fpreg
+accessor callbacks as needed. Once that is
+accomplished, the resume
+accessor callback is invoked. The
+unw_resume
+routine then returns normally (that is, unlikely
+for local unwinding, unw_resume
+will always return for remote
+unwinding).
+.PP
+Most platforms reserve some registers to pass arguments to exception
+handlers (e.g., IA\-64 uses r15\-r18
+for this
+purpose). These registers are normally treated like ``scratch\&''
+registers. However, if libunwind
+is used to set an exception
+argument register to a particular value (e.g., via
+unw_set_reg()),
+then unw_resume()
+will install this
+value as the contents of the register. In other words, the exception
+handling arguments are installed even in cases where normally only the
+``preserved\&'' registers are restored.
+.PP
+Note that unw_resume()
+does \fInot\fP
+invoke any unwind
+handlers (aka, ``personality routines\&''). If a program needs this, it
+will have to do so on its own by obtaining the unw_proc_info_t
+of each unwound frame and appropriately processing its unwind handler
+and language\-specific data area (lsda). These steps are generally
+dependent on the target\-platform and are regulated by the
+processor\-specific ABI (application\-binary interface).
+.PP
+.SH RETURN VALUE
+
+.PP
+For local unwinding, unw_resume()
+does not return on success.
+For remote unwinding, it returns 0 on success. On failure, the
+negative value of one of the errors below is returned.
+.PP
+.SH THREAD AND SIGNAL SAFETY

+
+.PP
+The unw_set_fpreg()
+routine sets the value of register

+.PP
+The register numbering is target\-dependent and described in separate
+manual pages (e.g., libunwind\-ia64(3) for the IA\-64 target).
+Furthermore, the exact set of accessible registers may depend on the
+type of frame that cp
+is referring to. For ordinary stack
+frames, it is normally possible to access only the preserved
+(``callee\-saved\&'') registers and frame\-related registers (such as the
+stack\-pointer). However, for signal frames (see
+unw_is_signal_frame(3)),
+it is usually possible to access
+all registers.
+.PP
+Note that unw_set_fpreg()
+can only write the contents of
+floating\-point registers. See unw_set_reg(3)
+for a way to
+write registers which fit in a single word.
+.PP
+.SH RETURN VALUE
+
+.PP
+On successful completion, unw_set_fpreg()
+returns 0.
+Otherwise the negative value of one of the error\-codes below is

+
+/* This header file defines the format of a DWARF exception-header
+ section (.eh_frame_hdr, pointed to by program-header
+ PT_GNU_EH_FRAME). The exception-header is self-describing in the
+ sense that the format of the addresses contained in it is expressed
+ as a one-byte type-descriptor called a "pointer-encoding" (PE).
+
+ The exception header encodes the address of the .eh_frame section
+ and optionally contains a binary search table for the
+ Frame Descriptor Entries (FDEs) in the .eh_frame. The contents of
+ .eh_frame has the format described by the DWARF v3 standard
+ (http://www.eagercon.com/dwarf/dwarf3std.htm), except that code
+ addresses may be encoded in different ways. Also, .eh_frame has
+ augmentations that allow encoding a language-specific data-area
+ (LSDA) pointer and a pointer to a personality-routine.
+
+ Details:
+
+ The Common Information Entry (CIE) associated with an FDE may
+ contain an augmentation string. Each character in this string has
+ a specific meaning and either one or two associated operands. The
+ operands are stored in an augmentation body which appears right
+ after the "return_address_register" member and before the
+ "initial_instructions" member. The operands appear in the order
+ in which the characters appear in the string. For example, if the
+ augmentation string is "zL", the operand for 'z' would be first in
+ the augmentation body and the operand for 'L' would be second.
+ The following characters are supported for the CIE augmentation
+ string:
+
+ 'z': The operand for this character is a uleb128 value that gives the
+ length of the CIE augmentation body, not counting the length
+ of the uleb128 operand itself. If present, this code must
+ appear as the first character in the augmentation body.
+
+ 'L': Indicates that the FDE's augmentation body contains an LSDA
+ pointer. The operand for this character is a single byte
+ that specifies the pointer-encoding (PE) that is used for
+ the LSDA pointer.
+
+ 'R': Indicates that the code-pointers (FDE members
+ "initial_location" and "address_range" and the operand for
+ DW_CFA_set_loc) in the FDE have a non-default encoding. The
+ operand for this character is a single byte that specifies
+ the pointer-encoding (PE) that is used for the
+ code-pointers. Note: the "address_range" member is always
+ encoded as an absolute value. Apart from that, the specified
+ FDE pointer-encoding applies.
+
+ 'P': Indicates the presence of a personality routine (handler).
+ The first operand for this character specifies the
+ pointer-encoding (PE) that is used for the second operand,
+ which specifies the address of the personality routine.
+
+ If the augmentation string contains any other characters, the
+ remainder of the augmentation string should be ignored.
+ Furthermore, if the size of the augmentation body is unknown
+ (i.e., 'z' is not the first character of the augmentation string),
+ then the entire CIE as well all associated FDEs must be ignored.
+
+ A Frame Descriptor Entries (FDE) may contain an augmentation body
+ which, if present, appears right after the "address_range" member
+ and before the "instructions" member. The contents of this body
+ is implicitly defined by the augmentation string of the associated
+ CIE. The meaning of the characters in the CIE's augmentation
+ string as far as FDEs are concerned is as follows:
+
+ 'z': The first operand in the FDE's augmentation body specifies
+ the total length of the augmentation body as a uleb128 (not
+ counting the length of the uleb128 operand itself).
+
+ 'L': The operand for this character is an LSDA pointer, encoded
+ in the format specified by the corresponding operand in the
+ CIE's augmentation body.

+/* This file defines the runtime-support routines for dynamically
+generated code. Even though it is implemented as part of libunwind,
+it is logically separate from the interface to perform the actual
+unwinding. In particular, this interface is always used in the
+context of the unwind target, whereas the rest of the unwind API is
+used in context of the process that is doing the unwind (which may be
+a debugger running on another machine, for example).
+
+Note that the data-structures declared here server a dual purpose:
+when a program registers a dynamically generated procedure, it uses
+these structures directly. On the other hand, with remote-unwinding,
+the data-structures are read from the remote process's memory and
+translated into internalized versions. To facilitate remote-access,
+the following rules should be followed in declaring these structures:
+
+ (1) Declare a member as a pointer only if the the information the
+ member points to needs to be internalized as well (e.g., a
+ string representing a procedure name should be declared as
+ "const char *", but the instruction pointer should be declared
+ as unw_word_t).
+
+ (2) Provide sufficient padding to ensure that no implicit padding
+ will be needed on any of the supported target architectures. For
+ the time being, padding data structures with the assumption that
+ sizeof (unw_word_t) == 8 should be sufficient. (Note: it's not
+ impossible to internalize structures with internal padding, but
+ it does make the process a bit harder).
+
+ (3) Don't declare members that contain bitfields or floating-point
+ values.
+
+ (4) Don't declare members with enumeration types. Declare them as
+ int32_t instead. */

+ o To ensure a stack can be unwound even when a process
+ is out of memory.
+
+ o To ensure a stack can be unwound at any time in a
+ multi-threaded process (e.g., even at a time when the normal
+ malloc-lock is taken, possibly by the very thread that is
+ being unwind).
+
+
+ To achieve the second objective, memory pools allocate memory
+ directly via mmap() system call (or an equivalent facility).
+
+ The first objective is accomplished by reserving memory ahead of
+ time. Since the memory requirements of stack unwinding generally
+ depends on the complexity of the procedures being unwind, there is
+ no absolute guarantee that unwinding will always work, but in
+ practice, this should not be a serious problem. */

+# The -version-info flag accepts an argument of the form
+# `current[:revision[:age]]'. So, passing `-version-info 3:12:1' sets
+# current to 3, revision to 12, and age to 1.
+
+# If either revision or age are omitted, they default to 0. Also note
+# that age must be less than or equal to the current interface number.
+
+# Here are a set of rules to help you update your library version
+# information:
+
+# 1. Start with version information of `0:0:0' for each libtool
+# library.
+
+# 2. Update the version information only immediately before a public
+# release of your software. More frequent updates are unnecessary,
+# and only guarantee that the current interface number gets larger
+# faster.
+
+# 3. If the library source code has changed at all since the last
+# update, then increment revision (`c:r:a' becomes `c:r+1:a').
+
+# 4. If any interfaces have been added, removed, or changed since the
+# last update, increment current, and set revision to 0.
+
+# 5. If any interfaces have been added since the last public release,
+# then increment age.
+
+# 6. If any interfaces have been removed since the last public
+# release, then set age to 0.

+# current to 3, revision to 12, and age to 1.
+
+# If either revision or age are omitted, they default to 0. Also note
+# that age must be less than or equal to the current interface number.
+
+# Here are a set of rules to help you update your library version
+# information:
+
+# 1. Start with version information of `0:0:0' for each libtool
+# library.
+
+# 2. Update the version information only immediately before a public
+# release of your software. More frequent updates are unnecessary,
+# and only guarantee that the current interface number gets larger
+# faster.
+
+# 3. If the library source code has changed at all since the last
+# update, then increment revision (`c:r:a' becomes `c:r+1:a').
+
+# 4. If any interfaces have been added, removed, or changed since the
+# last update, increment current, and set revision to 0.
+
+# 5. If any interfaces have been added since the last public release,
+# then increment age.
+
+# 6. If any interfaces have been removed since the last public
+# release, then set age to 0.
+
+# Tell versions [3.59,3.63) of GNU make to not export all variables.
+# Otherwise a system limit (for SysV at least) may be exceeded.

+because UNIX/Linux allow for stack-switching via sigaltstack(2).
+Specifically, this means that any given stacked register may or may
+not be backed up by memory in the current stack. If not, then the
+backing memory may be found in any of the "more inner" (younger)
+stacks. The routines in this file help manage the discontiguous
+nature of the register backing store. The routines are completely
+independent of UNIX/Linux, but each stack frame that switches the
+backing store is expected to reserve 4 words for use by libunwind. For

+- the frame state consists of the following:
+
+ - ip current instruction pointer
+ - sp current stack pointer value
+ - bsp current backing store pointer
+ - cfm current frame mask
+
+ these are derived from the next younger (more deeply nested) frame
+ as follows:
+
+ - ip == saved return-link (may be b0 or an alternate branch-reg)
+ - sp == if younger frame has a fixed-sized frame, sp + size-of-frame,
+ else saved sp
+ - cfm == saved ar.pfs
+ - bsp == if ar.bsp has been saved, saved ar.bsp, otherwise,
+ ar.bsp \ominus saved ar.pfs.pfm.sol
+
+The unwind cursor should represent the machine state as it existed at
+the address contained in register ip. This state consists of the
+*current* frame state and the save locations in the next younger
+frame.
+
+An unwind script current takes the old save locations and updates them
+for the next older frame. With the new setup, we need to update the
+frame state first, without updating the other save locations. For this
+to work, we need the following info:
+
+ - save location of return-link
+ - save location of ar.pfs
+ - save location of bsp (if it has been saved)
+ - size of stack frame (fixed case) or save location of sp
+
+
+setup:
+
+ func: ...
+ ...
+ ...
+ br.call foo <-- call site
+ ... <-- ip
+ ...
+
+initial state:
+
+ The unwind cursor represents the (preserved) machine state
+ as it existed at "ip".
+
+ Evaluating the unwind descriptors for "ip" yields the following
+ info:
+
+ - frame size at call site (or previous sp)
+ - what registers where saved where by func before
+ the call site was reached
+
+
+ Note that there is some procedure info that needs to be obtained
+ for the new "ip" which is contained in the unwind descriptors.
+ Specifically, the following is needed:
+
+ - procedure's start address
+ - personality address
+ - pointer to language-specific data area
+
+ This info is stored in a separate proc_info structure and needs
+ to be obtained right after running the unwind script for func.

+/* Logically, we like to think of the stack as a contiguous region of
+memory. Unfortunately, this logical view doesn't work for the
+register backing store, because the RSE is an asynchronous engine and
+because UNIX/Linux allow for stack-switching via sigaltstack(2).
+Specifically, this means that any given stacked register may or may
+not be backed up by memory in the current stack. If not, then the
+backing memory may be found in any of the "more inner" (younger)
+stacks. The routines in this file help manage the discontiguous
+nature of the register backing store. The routines are completely
+independent of UNIX/Linux, but each stack frame that switches the
+backing store is expected to reserve 4 words for use by libunwind. For
+example, in the Linux sigcontext, sc_fr[0] and sc_fr[1] serve this
+purpose. */

+
+ This is used by backtrace() implementation to accelerate frequent

+ stack levels. The first frame, backtrace itself, is omitted. When
+ called, SIZE should give the maximum number of entries that can be
+ stored into BUFFER. Uses an internal thread-specific cache to
+ accelerate queries.
+
+ The caller should fall back to a unw_step() loop if this function
+ fails by returning -UNW_ESTOPUNWIND, meaning the routine hit a
+ stack frame that is too complex to be traced in the fast path.
+
+ This function is tuned for clients which only need to walk the
+ stack to get the call tree as fast as possible but without any
+ other details, for example profilers sampling the stack thousands
+ to millions of times per second. The routine handles the most
+ common x86-64 ABI stack layouts: CFA is RBP or RSP plus/minus
+ constant offset, return address is at CFA-8, and RBP and RSP are
+ either unchanged or saved on stack at constant offset from the CFA;
+ the signal return frame; and frames without unwind info provided
+ they are at the outermost (final) frame or can conservatively be
+ assumed to be frame-pointer based.
+
+ Any other stack layout will cause the routine to give up. There
+ are only a handful of relatively rarely used functions which do
+ not have a stack in the standard form: vfork, longjmp, setcontext
+ and _dl_runtime_profile on common linux systems for example.
+
+ On success BUFFER and *SIZE reflect the trace progress up to *SIZE
+ stack levels or the outermost frame, which ever is less. It may
+ stop short of outermost frame if unw_step() loop would also do so,
+ e.g. if there is no more unwind information; this is not reported
+ as an error.
+
+ The function returns a negative value for errors, -UNW_ESTOPUNWIND
+ if tracing stopped because of an unusual frame unwind info. The
+ BUFFER and *SIZE reflect tracing progress up to the error frame.
+
