--- Comment #12 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-14 branch has been updated by Peter Bergner <berg...@gcc.gnu.org>: https://gcc.gnu.org/g:1205104bbef40abe3baa5965a676f3b0f68971dd commit r14-10476-g1205104bbef40abe3baa5965a676f3b0f68971dd Author: René Rebe <r...@exactcode.de> Date: Fri Jul 12 21:17:08 2024 +0000 rs6000: Fix .machine cpu selection w/ altivec [PR97367] There are various non-IBM CPUs with altivec, so we cannot use that flag to determine which .machine cpu to use, so ignore it. Emit an additional ".machine altivec" if Altivec is enabled so that the assembler doesn't require an explicit -maltivec option to assemble any Altivec instructions for those targets where the ".machine cpu" is insufficient to enable Altivec. For example, -mcpu=G5 emits a ".machine power4". 2024-07-18 René Rebe <r...@exactcode.de> Peter Bergner <berg...@linux.ibm.com> gcc/ PR target/97367 * config/rs6000/rs6000.cc (rs6000_machine_from_flags): Do not consider OPTION_MASK_ALTIVEC. (emit_asm_machine): For Altivec compiles, emit a ".machine altivec". gcc/testsuite/ PR target/97367 * gcc.target/powerpc/pr97367.c: New test.
