Hi all,This patch generalises the TARGET_MACRO_FUSION_PAIR_P hook usage to work on more than just compares and conditional branches for which it was initially designed for (for x86). There are some instructions in arm and aarch64 that can be fused together when they're back to back in the instruction stream and I'd like to use this hook to keep them together. I'll post an implementation of TARGET_MACRO_FUSION_PAIR_P for arm and aarch64 shortly... Bootstrapped and tested on x86, aarch64-none-linux-gnu and arm-none-linux-gnueabihf.
