This patch enables using those instructions if -mcpu=future is used. 2024-05-03 Michael Meissner gcc/ * config/rs6000/rs6000-cpus.def (ISA_FUTURE_MASKS_SERVER): Enable using load vector pair and store vector pair instructions for memory copy operations. (POWERPC_MASKS): Make the bit for enabling using load vector pair and store vector pair operations set and reset when the PowerPC processor is changed.
