Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |hjl.tools at gmail dot com, | |jakub at gcc dot gnu.org --- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- This one is because of: /* See if arch, tune, etc. are the same. */ else if (caller_opts->arch != callee_opts->arch) ret = false; For tune we ignore it if always_inline, the question is what should we do for arch for always_inline. I'm afraid we don't have a notion of arches being subset or superset of each other.
