--- Comment #15 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Peter Bergner <berg...@gcc.gnu.org>: https://gcc.gnu.org/g:319b57fb02b52ba9036c00dda36ff28d8274e13d commit r12-10628-g319b57fb02b52ba9036c00dda36ff28d8274e13d 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.
