Patches applied to gcc-4.4.0:

Please include a change to this file with each patch, *and* each
subsequent modification of the patch.  Do NOT combine patch
checkins, keep them separate.

Append new entries to the end of this file. Each entry shall include:
 * The list of files modified by the patch,
 * The status of the patch (already upstream (indicate upstream revision),
   not yet upstream, or not applicable upstream (google local).
 * The local 'owner' responsible for the patch, and
 * A description of the patch (preferably including bug numbers).

Please include entries for both local patches and for patches which
have been checked in to (or back-ported from) the upstream sources.
When checking in changes made upstream, add an entry to this file but
DO NOT add entries to the GNU ChangeLog files.

  Added --with-native-system-header-dir to specify the location of
  /usr/include instead of having it hard-coded.  This is especially useful
  when building a sysroot'ed cross-compiler and you want to relocate
  everything inside the system root.  Without this, the Makefile and
  configure scripts assume system header files live in /usr/include (or in
  usr/include under the system root directory).  This option is (partially)
  overridden in the Makefile by targets whose makefile fragments define
  NATIVE_SYSTEM_HEADER_DIR.  For those, the include searching done in
  configure wasn't relevant or correct anyway.

gcc/config/i386/i386.c
  Use __x86.get_pc_thunk rather than __i686.get_pc_thunk as the prefix
  of 32-bit PC-getting thunk names to facilitate conversion of gcc -S
  output into .S files.  (__i686 is defined as 1 by the preprocessor if
  -mtune=pentiumpro or later is used.  If thunk names use __i686, then
  when converting gcc -S output into .S files people need to replace
  __i686 with some other string.)

  In GLIBCXX_EXPORT_FLAGS (in acinclude.m4), substitute new variable
  DETERMINISM_CXXFLAGS.  This variable uses -frandom-seed= to give each

  Implement stack probing for x86 by extending -mstack-arg-probe to work on
  all x86 targets (it worked on only Windows x86 targets earlier).
  Also, change the meaning of -fstack-check to mean -mstack-arg-probe on x86.
  A similar patch was sent to the gcc-patches@ mailing list, only to be
  rejected by Eric Botcazou because he claimed to have a superior
  -fstack-check implementation in the works. So this patch will not be
  submitted upstream. This google-local patch will become unnecessary when
  Eric Botcazou's new -fstack-check implementation comes in (hopefully in
  time for the next crosstools release).
