Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |uros at gcc dot gnu.org --- Comment #32 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Then maybe r13-6361-g8020c9c42349f51f75239b is the commit that changed it? Would be good to put a breakpoint at that instruction and see in which iteration it results in NaN and what operands it had...
