From: "aj at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/39222] New: out of memory bootstrapping Date: Tue, 17 Feb 2009 21:09:00 -0000 [thread overview] Message-ID: <bug-39222-260@http.gcc.gnu.org/bugzilla/> (raw) On my Linux/x86-64 system using --enable-checking=yes,rtl, I get a bootstrap failure since revision 144100 - revision was good 144099. Difference between the two revisions is: +2009-02-11 Uros Bizjak <ubizjak@gmail.com> + Jakub Jelinek <jakub@redhat.com> + + PR target/39118 + * config/i386/i386.md (UNSPEC_MEMORY_BLOCKAGE): New constant. + (memory_blockage): New expander. + (*memory_blockage): New insn pattern. + * config/i386/i386.c (ix86_expand_prologue): Use memory_blockage + instead of general blockage at the end of function prologue when + frame pointer is used to access red zone area.
