From: "steven at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug rtl-optimization/24257] [4.1 Regression] ICE: in extract_insn with -O -fgcse -fgcse-sm Date: Wed, 16 Nov 2005 08:52:00 -0000 [thread overview] Message-ID: <20051116085240.25884.qmail@sourceware.org> (raw) In-Reply-To: <bug-24257-8707@http.gcc.gnu.org/bugzilla/> ------- Comment #10 from steven at gcc dot gnu dot org 2005-11-16 08:52 ------- Re. comment #9 GCSE store motion is very broken, and it's really been like that for a long time. And it doesn't really do much, either, when you turn it on. Sadly we have nothing to replace it right now except the loop store motion in tree-ssa-loop-im.c, which doesn't work as well as GCSE store motion due to alias representation issues at the tree level. We're just going to have to fix this one IMHO. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24257
