Lu Date: Sat Jul 17 07:44:45 2021 -0700 : Add pragma GCC target("general-regs-only") 1. Intrinsics in only require GPR ISAs. Add #if defined __MMX__ || defined __SSE__ #pragma GCC push_options #pragma GCC target("general-regs-only") #define __DISABLE_GENERAL_REGS_ONLY__ #endif and #ifdef __DISABLE_GENERAL_REGS_ONLY__ #undef __DISABLE_GENERAL_REGS_ONLY__ #pragma GCC pop_options #endif /* __DISABLE_GENERAL_REGS_ONLY__ */ to to disable non-GPR ISAs so that they can be used in functions with __attribute__ ((target("general-regs-only"))). 2.
