Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Keywords| |lto --- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> --- All ABI changing options should be also enabled for LTO and they also deserve handling in lto-opts.c (always stream, not only if explicitely set) and lto-wrapper.c (diagnose mismatches and force a setting for the link stage). At least enabling them for LTO is minimally required, like you suggest.
