gcc-4.4.3/README.google

Patches applied to gcc-4.4.3:

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. Should be one of:
   - already upstream (indicate upstream revision),
   - not yet upstream, or
   - google-local (not applicable upstream).
 * 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.

  Fold SYSROOT_CFLAGS_FOR_TARGET (set by --with-build-sysroot) into
  FLAGS_FOR_TARGET.  The old mechanism breaks target libraries which use
  libtool (e.g. libmudflap) because libtool filters out --sysroot when linking.
  However, FLAGS_FOR_TARGET gets hard-coded into libtool's LTCC variable, so
  any flags set there are used unconditionally.

  Chronic failing tests marked locally as ilp32-only, to permit the gcc
  continuous build to scan for a clean sweep of testsuite tests.  Ideally
  these tests would be marked XFAIL, but XFAIL functionality is not currently

  - Do not open gcda/gcno files in write mode unnecessarily.
  - Fix a bug in gimple_stringop_fixed_value where it assumed all
    stringops have 3 arguments, even though bzero only has two.
  - Call df_note_add_problem in iv_analysis_loop_init since
    loop-iv calls single_set which depends on the notes being
    correct.  This fixes an ICE caused by GCSE invalidating the
    notes, and the invalid notes being used by IV opts.
  - Backport upstream revision 150544.  This makes the compiler
    more robust in the face of bad .gcda files by initializing
    pid_map to NULL rather than leaving uninitialized values in
    it.
  - Backport upstream revision 152612.  Do not mark #ident and #sccs
    as deprecated.

  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 -- the middle-end
  part is submitted to gcc-4.5, and the x86 target-specific part is yet to
  be submitted:
