Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |ASSIGNED Assignee|unassigned at gcc dot gnu.org |jakub at gcc dot gnu.org --- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- The bug is that nothing calls ix86_fixup_binary_operands_no_copy on it. Now, either we can call it in the new cond_ expander, or better follow what other spots do and have just define_insn * with ix86_binary_operator_ok even for the mask cases and add define_expand that calls ix86_fixup_binary_operands_no_copy.
