From: yulong <shiyul...@iscas.ac.cn> This patchset adds support for three recently ratified RISC-V extensions:
- Zicbom (Cache-Block Management Instructions) - Zicbop (Cache-Block Prefetch hint instructions) - Zicboz (Cache-Block Zero Instructions) Patch 1: Add Zicbom/z/p mininal support Patch 2: Add Zicbom/z/p instructions arch support Patch 3: Add Zicbom/z/p instructions testcases diff with the previous version: We use unspec_volatile instead of unspec for those cache operations, and move those UNSPEC from unspec to unspecv. 19 20 cf. <https://github.com/riscv/riscv-CMOs/blob/fc8e97a9531ac9811971a182ae431976b86216e1/specifications/cmobase-v1.0-rc2.pdf>; yulong (3): RISC-V: Add mininal support for Zicbo[mzp] RISC-V:Cache Management Operation instructions RISC-V:Cache Management Operation instructions testcases gcc/common/config/riscv/riscv-common.cc | 8 +++ gcc/config/riscv/predicates.md | 4 ++ gcc/config/riscv/riscv-builtins.cc | 16 ++++++ gcc/config/riscv/riscv-cmo.def | 17 +++++++ gcc/config/riscv/riscv-ftypes.def | 4 ++ gcc/config/riscv/riscv-opts.h | 8 +++ gcc/config/riscv/riscv.md | 51 +++++++++++++++++++ gcc/config/riscv/riscv.opt | 3 ++ gcc/testsuite/gcc.target/riscv/cmo-zicbom-1.c | 21 ++++++++ gcc/testsuite/gcc.target/riscv/cmo-zicbom-2.c | 21 ++++++++ gcc/testsuite/gcc.target/riscv/cmo-zicbop-1.c | 23 +++++++++ gcc/testsuite/gcc.target/riscv/cmo-zicbop-2.c | 23 +++++++++ gcc/testsuite/gcc.target/riscv/cmo-zicboz-1.c | 9 ++++ gcc/testsuite/gcc.target/riscv/cmo-zicboz-2.c | 9 ++++ 14 files changed, 217 insertions(+) create mode 100644 gcc/config/riscv/riscv-cmo.def create mode 100644 gcc/testsuite/gcc.target/riscv/cmo-zicbom-1.c create mode 100644 gcc/testsuite/gcc.target/riscv/cmo-zicbom-2.c create mode 100644 gcc/testsuite/gcc.target/riscv/cmo-zicbop-1.c create mode 100644 gcc/testsuite/gcc.target/riscv/cmo-zicbop-2.c create mode 100644 gcc/testsuite/gcc.target/riscv/cmo-zicboz-1.c create mode 100644 gcc/testsuite/gcc.target/riscv/cmo-zicboz-2.c -- 2.17.1
