-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.
-
- 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.

+## Libc Requirements
+
+libunwind depends on getcontext(), setcontext() functions which are missing
+from C libraries like musl-libc because they are considered to be "obsolescent"
+API by POSIX document. The following table tries to track current status of
+such dependencies
+
+ - r, requires
+ - p, provides its own implementation
+ - empty, no requirement
+
+| Architecture | getcontext | setcontext |
+|--------------|------------|------------|
+| aarch64 | p | |
+| arm | p | |
+| hppa | p | p |
+| ia64 | p | r |

+
+## General Build Instructions
In general, this library can be built and installed with the following
commands:
- $ ./autogen.sh # Needed only for building from git. Depends on libtool.
- $ ./configure
- $ make
- $ make install prefix=PREFIX
+ $ 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.
+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
+### Building with Intel compiler
-** Version 8 and later
+#### 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
+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$PWD/src/.libs"
+ LDFLAGS="-L$PWD/src/.libs"
-* Building on HP-UX
+### Building on HP-UX
For the time being, libunwind must be built with GCC on HP-UX.
$ ./configure CFLAGS="-g -O2 -mlp64" CXXFLAGS="-g -O2 -mlp64"
-Caveat: Unwinding of 32-bit (ILP32) binaries is not supported
- at the moment.
+Caveat: Unwinding of 32-bit (ILP32) binaries is not supported at the moment.
-** Workaround for older versions of GCC
+### Workaround for older versions of GCC
-GCC v3.0 and GCC v3.2 ship with a bad version of sys/types.h. The
+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":
+`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
+### Building for PowerPC64 / Linux
For building for power64 you should use:
- $ ./configure CFLAGS="-g -O2 -m64" CXXFLAGS="-g -O2 -m64"
+ $ ./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"
+
+ $ ./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
+it with `-O0`, without optimizations. There are some compiler problems
depending on the version of your gcc.
-* Building on FreeBSD

+### 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)
+* `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.

-# exported API, or moved to Autoconf or Automake where they belong.

-# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN

-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)

-# So we provide this file, which has a silly filename so it's always
-# included after everything else. This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.

-# 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 1.2 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]
- --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]

-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
- (and sometimes confusing) to the casual installer
- --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-ptrace building libunwind-ptrace library
- --enable-setjmp building libunwind-setjmp library
- --disable-documentation Disable generating the man pages
- --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 try to use only PIC/non-PIC objects [default=use
- both]
- --with-gnu-ld assume the C compiler uses GNU ld [default=no]
-
-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 C/C++/Objective 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.
-
-Report bugs to <libunwind-devel@nongnu.org>.

-# 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.
-
-# 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.

+- 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.

+# CFI expressions were added in DWARF v3 to allow compilers to specify memory
+# locations or register values using DWARF programs. These programs are simple
+# stack-based operations which allow the compiler to encode integer mathematics
+# and other complex logic. CFI expressions are therefore more powerful than the
+# conventional register + offset schemes.
+#
+# These tests capture a bug we have fixed in libunwind. CFI expression programs
+# always start with the current CFA pushed onto the stack. This file contains a
+# pair of routines which test CFI expression parsing. Specifically they test
+# DW_CFA_expression logic, which uses DWARF expressions to compute the address
+# where a non-volatile register was stored.
+#
+# Main calls DW_CFA_expression_testcase, which sets up known state in a
+# non-volatile (caller-saved) register. We use r12 for this purpose. After this
+# DW_CFA_expression_testcase then calls DW_CFA_expression_inner, which clobbers
+# r12 after stashing its value on the stack. This routine contains a DWARF3 CFI
+# expression to restore the value of r12 on unwind which should allow libunwind
+# to recover clobbered state. DW_CFA_expression_inner calls recover_register to
+# retrieve the cached register value. This function recovers the register value
+# by using libunwind to unwind the stack through DW_CFA_expression_inner and up
+# to the call site in DW_CFA_expression_testcase. If our expression is correct,
+# libunwind will be able to restore r12 from the stack.
+#
+# BE CAREFUL WITH rdi, rsi, rax HERE! The arguments to recover_register are
+# passed in via rdi, rsi and I just let them flow through unchanged. Similarly
+# RAX flows back unchanged. Adding any function calls to the below may clobber
+# these registers and cause this test to fail mysteriously.
