This patch re-enables using load and store vector pair instructions. Previously the -mblock-ops-vector-pair switch was not set in POWERPC_MASKS. This means the option was not reset if the cpu was changed via target attributes or targt pragmas. I added this mask to POWERPC_MASKS since the option is set via -mcpu=future. 2024-02-15 Michael Meissner gcc/ * config/rs6000/rs6000-cpus.def (ISA_FUTURE_MASKS_SERVER): Turn on -mblock-ops-vector-pair for -mcpu=future. (POWERPC_MASKS): Add -mblock-ops-vector-pair.
