--- Comment #15 from Segher Boessenkool <segher at gcc dot gnu.org> --- (In reply to bugreporter66 from comment #14) > I should be able to workaround that by emulating all LE targets on POWER9, > with a comment that building for POWER8 natively on target should work too. If you want to default to Power9 but still support Power8 (on builds that use -mcpu=power8), you need to set up appropriate multilibs. If you want that, please do a feature request for that? As a new PR, not hidden inside this one please :-)
