+ 14278
+
+* Support for the x32 ABI on x86-64 added. The x32 target is selected by
+ configuring glibc with:
+ BUILD_CC='gcc' CC='gcc -mx32' CXX='g++ -mx32'
+ Visit <http://sites.google.com/site/x32abi/> for more x32 ABI info.
+ Implemented by H.J. Lu.
* ISO C11 support:
Implemented by Ulrich Drepper.
-* Support for the IA-64 is removed and could live in ports.
+* Support for the IA-64 has been moved to ports.
* Remove support for anything but ELF binary format
* More generic and 64-bit performance optimizations to math functions.
Implemented by Ulrich Drepper.
+
+* New configure option --enable-obsolete-rpc makes the deprecated RPC
+ headers and functions available at compile time as they were before
+ version 2.14. This option will be removed at some time in the future
+ after the TI-RPC library becomes fully sufficient for the needs of
+ existing applications.
+
+* Compatibility code for Linux kernel versions before 2.4 has been removed.
+ Note that glibc is not expected to work with any Linux kernel version
+ before 2.6.
+
+* New header <sys/auxv.h> and function getauxval allowing easy access to
+ the AT_* key-value pairs passed from the Linux kernel. The header also
+ defines the HWCAP_* bits associated with the AT_HWCAP key.
+
+* New locales: mag_IN
+
+* New configure option --enable-systemtap builds SystemTap static probes
+ into libc for setjmp and longjmp and into libpthread for various operations.
+ So far the setjmp/longjmp probes and some of the libpthread probes are
+ provided only for i*86 and x86_64.
+ Implemented by Roland McGrath and Rayson Ho.
+
+* Optimized expf for x86-32 and x86-64. Implemented by Liubov Dmitrieva.
+
+* More optimized functions for PowerPC. Implemented by Adhemerval Zanella
+ and Will Schmidt.
+
+* More optimized functions for SPARC. Implemented by David S. Miller.
+
+* Improved support for cross-compilation, especially bootstrap builds
+ without a previously built glibc.
+
+* Ports for the TILE-Gx and TILEPro families of processors. Contributed by
+ Chris Metcalf from Tilera.
+
+* Support for the old ARM ABI has been removed from ports. Only the EABI is
+ now supported for ARM processors.
+
+* The hard-float variant of the ARM EABI now uses /lib/ld-linux-armhf.so.3
+ as the name of the dynamic linker, to distinguish it from the
+ /lib/ld-linux.so.3 dynamic linker used for the base EABI.
+
+* Support for CRIS has been removed from ports.
+
+* A new class of installed header has been documented for low-level
+ platform-specific functionality. PowerPC added the first instance with a
+ function to provide time base register access. Contributed by Tulio
+ Magno Quites Machado Filho.
+
+* ix86 configurations now install header files that are consistent with
+ what x86-64 configurations install. These same header files can be used
+ for -m32, -m64, or -mx32 builds.
+ Contributed by H.J. Lu.
+
+* Math library bug fixes. A thorough audit of all open math library bugs was
+ conducted by Joseph Myers. Significant progress was made on many math
+ library bugs resulting in more accurate exceptions and function results.
+ Many thanks to all those that contributed including Andreas Jaeger for his
+ patch review and work on the x87 trigonometric instruction issues.
+
+* Timezone data is no longer installed. Timezone-related binaries and scripts
+ will continue to be installed. Users should obtain their timezone data from
+ their distribution provider or from the tzdata package at
+ <ftp://munnari.oz.au/pub/>.
\f
Version 2.15
Implemented by Ulrich Drepper.
* Faster sqrt and sqrtf implemention for some PPC variants.
- Implemented by Stephen Munroe.
+ Implemented by Steven Munroe.

Version 2.7
Masahide Washizawa.
* IA-64 port by Jes Sorensen and HJ Lu.

-Compiling the GNU C Library for Linux/ia64
-******************************************
-
- Please refer to the file INSTALL in the same directory as you found
-this file for general information about configuring and compiling
-glibc.
-
- For general inquiries about glibc under Linux/ia64 please use the
-following mailing list linux-ia64@linuxia64.org or one of the relevant
-glibc mailing lists.
-
-Recommended Tools for Compilation
-=================================
-
- In order for glibc-2.2 to build correctly on the ia64 you need at
-least the following versions of the GNU tools (the :
-
- * The Cygnus toolchain snapshot for the ia64 as of August 4
- including the provided set of patches. It is however recommend
- you use the October 24 toolchain snapshot or a more recent version.
-
- OR alternatively you can try the following (the Cygnus toolchain is
- the recommended solution):
-
- * GCC and binutils, GAS and GNU LD out of CVS from
- sources.redhat.com as of August 28, 2000 or later. The CVS tree
- may require special patches to work properly on the ia64.
-
-Configuring and compiling GNU Libc for Linux/ia64
-=================================================
-
- The library requires Linux kernel version 2.4.0-test4-000728 or
-later to funtion properly. Besides that it support for debug libraries
-is currently untested. Hence the following options
-are required for configuring the library:
-
- --disable-debug --enable-kernel=2.4.0
-
- It is also important that you make sure the library picks up the
-appropriate kernel header files, if you do not have recent enough
-kernel headers in /usr/src/linux/include, you should use the
---with-headers=<path> option to specify the location.
-
- As an example I personally use the following options to configure
-the library:
-
- --disable-debug
- --disable-cvs
- --enable-kernel=2.4.0
- --host=ia64-linux
- --enable-add-ons=yes
- --prefix=/usr
- --with-headers=/home/jes/linux/include
-
-
-Good luck
