This patch enables generating load and store vector pair instructions when doing certain memory copy operations when -mcpu=future is used. In doing tests on power10, it was determined that using these instructions were problematical in a few cases, so we disabled generating them by default. This patch re-enabled generating these instructions if -mcpu=future is used. The patches have been tested on the following platforms. I added the patches for PR target/107299 that I submitted on November 2nd before doing the builds so that GCC would build on systems using IEEE 128-bit long double. * https://gcc.gnu.org/pipermail/gcc-patches/2022-November/604834.html 2023-10-16 Michael Meissner gcc/ * config/rs6000/rs6000-cpus.def (ISA_FUTURE_MASKS): Add -mblock-ops-vector-pair.
