Re: [PATCH v3] LoongArch: Split loongarch_option_override_internal into smaller procedures

v1 -> v2: - Rebased to master. - Specifies "(void)" for the empty parameter list of loongarch_global_init. v2 -> v3: - Keep the original option-processing behavior (-march=la664 enables -mrecip=all) and fix the ICE when -mfrecipe is not passed with -mrecip.

[PATCH v3] LoongArch: Split loongarch_option_override_internal into smaller procedures

gcc/ChangeLog: * config/loongarch/genopts/loongarch.opt.in: Mark -m[no-]recip as aliases to -mrecip={all,none}. * config/loongarch/loongarch.opt: Same. * config/loongarch/loongarch-def.h: Modify ABI condition macros for convenience. *
