Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Many of the *.opt changes are target specific, so you'd need to test it also across all targets, and furthermore it depends on what exactly is being saved/restored, many options might be at the same spot. So perhaps we want to compute some hash of the options stuff (e.g. compute it by the awk scripts that emit options*.[ch]) and use that to determine LTO compatibility in addition to the version?
