Just like the patch for AARCH64_FUSION_PAIR, this is a patch for AARCH64_EXTRA_TUNING_OPTION. Note I tested this patch on top of the patch for AARCH64_EXTRA_TUNING_OPTION.
Changes in v2: Remove the hack for AARCH64_EXTRA_TUNE_ALL. Remove index from AARCH64_EXTRA_TUNING_OPTION Instead of doing an explict index in aarch64-tuning-flags.def, we should have an enum which does the index instead. This allows you to add/remove them without worrying about the order being correct and having holes or worry about merge conficts. OK? Bootstrapped and tested on aarch64-linux-gnu with no regressions. ChangeLog: * config/aarch64/aarch64-tuning-flags.def: Remove all index to AARCH64_EXTRA_TUNING_OPTION. * config/aarch64/aarch64-protos.h (extra_tuning_flags_index): New enum. (aarch64_extra_tuning_flags): Base the shifted value on the index instead of the argument to AARCH64_EXTRA_TUNING_OPTION. * config/aarch64/aarch64.c: Remove the last argument to AARCH64_EXTRA_TUNING_OPTION..
