------- Comment #25 from hubicka at gcc dot gnu dot org 2008-02-06 11:30 ------- Hmm, sorry. IS_STACK_MODE obviously return false for SSE math, per Paolo's commit. Since it is not used except for the hacks to avoid constant hoisting, I guess it is OK. I will commit only the patch for pertial memory write and give it a try making this heuristic less active.
The code is question is simple loop initializing array with a constant. This seems like something we ought to get right -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23322
