--- Comment #6 from Kewen Lin <linkw at gcc dot gnu.org> --- I think this is related to r10-580-ge154242724b084 and this failure is expected and a use error. With it applied, we don't always pass -many to assembler with CHECKING_P enabled. Actually compilers (gcc-13, gcc-12, gcc-11 or trunk) generate the same assembly, but because gcc-11/gcc-12/gcc-13 is built with --checking=release by default which doesn't set CHECKING_P while trunk is built with --checking=yes,extra by default which set CHECKING_P. So it causes the different behaviors so that further considered as regression unexpectedly. The issue should be gone if trunk gets released as gcc-14 or it's built with --checking=release. IMO Alan's commit aims to help to expose more and more such unexpected use cases and users can fix them in place. As #c3 "PowerPC 7450 (aka PowerPC G4) is only capable of -maltivec but not -mvsx", so it's unexpected to have -mcpu=7450 meanwhile having -mvsx, could you check where the -mvsx comes from and fix it instead? Thanks! btw, a workaround option is to add -Wa,-many to restore the previous behavior that passing -many to assembler.
