--- Comment #12 from Florian Weimer <fw at gcc dot gnu.org> --- (In reply to Richard Biener from comment #10) > As of HTM it would make the testcase a user error - when using -mcpu=power10 > it would require building with -mcpu=power8 -mno-htm? Or -mcpu=power8 should imply -mno-htm. It's not 100% compatible for sure, but so is removing a feature from a later CPU that was present in an earlier version and enabled by default in GCC. I suspect it's better to take the compatibility hit at run time, rather than later at run time (once the users get their hands on POWER10 hardware).
