Subject: [PATCH v2 2/2] RISC-V: Implement new style of architecture extension test macros.
Date: Thu, 7 Jan 2021 17:55:44 +0800 [thread overview]
Message-ID: <20210107095544.20845-3-kito.cheng@sifive.com> (raw)
In-Reply-To: <20210107095544.20845-1-kito.cheng@sifive.com>
- 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.
(riscv_current_subset_list): New.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/predef-10.c: New.
* gcc.target/riscv/predef-11.c: New.
* gcc.target/riscv/predef-12.c: New.
* gcc.target/riscv/predef-13.c: New.
