X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e3354b6de7a348386425879847c4f18ef1e82791;p=gcc.git RISC-V: Implement new style of architecture extension test macros. - This patch introduce new set of architecture extension test macros which is accept on riscv-c-api-doc recently. - https://github.com/riscv/riscv-c-api-doc/blob/master/riscv-c-api.md#architecture-extension-test-macro - We will also mark deprecated for legacy architecture extension test macros in GCC 11, but still support that for 1 or 2 release cycles. gcc/ChangeLog: * common/config/riscv/riscv-common.c (riscv_current_subset_list): New. * config/riscv/riscv-c.c (riscv-subset.h): New. (INCLUDE_STRING): Define. (riscv_cpu_cpp_builtins): Add new style architecture extension test macros. * config/riscv/riscv-subset.h (riscv_subset_list::begin): New. (riscv_subset_list::end): New.
