Below, the cores that are ARMv8.2 based are referencing that file. However, if you are asking if that should be sufficient for those (instead of needing a core specific tuning), the answer appears to be no. If you compare the GCC flags for the generic 8.2 https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/config/aarch64/aarch64-arches.def;h=3be55fa29aa15cb19ab00aeb2edb156ad3d09aee;hb=HEAD and an A75 (which is 8.2 based) https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/config/aarch64/aarch64-cores.def;h=a7dde38d7687049825aec4eb9446e76db84cd9c0;hb=HEAD#l102 You will see the flags are different. Perhaps not sufficiently different for anything more than benchmarking, but that is a secondary discussion. Given that these will mostly be used by meta-arm-bsp machines, which will most likely want to be running as optimally as possible, then this is a good thing to have here. What I would like to do is actually include all of the 8.2 based cores into the conf/machine/include/arm/arch-armv8-2a.inc. This would stop the explosion of core specific tunes in conf/machine/include/ and nicely group them into a CPU generation family file. However, that might be contriversial. While that is being hashed out, this can be used here for those that need it. So, think of this patch as an intermediate step for that change.
