Last change on this file since c304f4c was 44426cf, checked in by Joe Ciccone <jciccone@…>, 17 years ago

Updated to Glibc 2.6. This includes adding a sed to Coreutils and Gzip to rename their internal implementations of futimens which are incompatible with the implementation provided by Glibc. Added a target tripplet based optimization to glibc on x86 and 32bit build on x86_64 so that glibc will build properly now that i386 is no longer supported. Also added a note to the build variables page the i386-pc-linux-gnu is not supported by glibc.

Description: This is a branch update for Glibc-2.6, and should be
             rechecked periodically. See the 'Changelog' and 'localedata/ChangeLog'
             for specific details.

2007-05-21  Jakub Jelinek  <jakub@redhat.com>

	* malloc/hooks.c (MALLOC_STATE_VERSION): Bump.
	(public_sET_STATe): If ms->version < 3, put all chunks into
	unsorted chunks and clear {fd,bk}_nextsize fields of largebin
	chunks.
	* malloc/malloc.c (do_check_malloc_state): Don't assert
	n_mmaps is not greater than n_mmaps_max.

	* malloc/malloc.c [MALLOC_DEBUG]: Revert 2007-05-13 changes.
	* malloc/hooks.c: Likewise.
	* malloc/arena.c: Likewise.
	* malloc/Makefile (CFLAGS-malloc.c): Revert accidental
	2007-05-07 commit.
