--- Comment #18 from Alexandre Oliva <aoliva at gcc dot gnu.org> --- Created attachment 59915 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=59915&action=edit add options to control the new ifcombine features This may be useful to figure out whether it's ifcombine that's slowing things down, and if so, which of the two major new features recently added to it caused it. I have tried it on x86_64 insn-attrtab, insn-output and insn-emit-*, and the negated options didn't have a measurable effect on compile time there, FWIW.
