Hi folks, Older versions of gcc are horrible for int128_t on aarch64, emitting a __multi3 call, which is slow and defeats the purpose. However, more recent versions of gcc (since 5, IIRC), do the right thing and produce the proper inlined instructions.
Do we have the infrastructure available to test for this, and conditionally set CONFIG_ARCH_SUPPORTS_INT128 if we do? Thanks, Jason
