Turn on -fomit-frame-pointer by default for 32bit Linux/x86.
2010-08-12 H.J. Lu <hongjiu.lu@intel.com>
Uros Bizjak <ubizjak@gmail.com>
* config.gcc: Handle --enable-frame-pointer.
* configure.ac: Add --enable-frame-pointer.
* configure: Regenerated.
* config/i386/i386.c (USE_IX86_FRAME_POINTER): Default to 0.
(override_options): If not configured with --enable-frame-pointer,
enable -fomit-frame-pointer (but not for TARGET_MACHO or when
optimizing for size), -fasynchronous-unwind-tables and
-maccumulate-outgoing-args by default.
