------- Additional Comments From kazu at cs dot umass dot edu 2004-12-09 03:35 ------- Created an attachment (id=7710) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=7710&action=view) a patch
This patch is fixes the bug but maybe a bit too conservative. If thread_across_edge gets a comparison "op0 code op1", and op0 and op1 are defined by PHI nodes at e->dest, we could still replace op0 and op1 with the PHI arguments before we look up the condition. With my patch, if the condition involves an SSA_NAME that is also used as a PHI argument at e->dest, I would guess that the lookup is very likely to fail. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18694 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
