------- Comment #6 from janis at gcc dot gnu dot org 2008-09-19 22:19 ------- Created an attachment (id=16365) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=16365&action=view) minimized C testcase
I don't yet understand what's going on but was able to come up with a relatively small executable test case in C. It fails with "-O1 -funsafe-math-optimizations" for r134833 but passes with those options for r134831. With r134833 it passes without -funsafe-math-optimizations. This testcase doesn't care about -ftree-fre. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37449
