Commit Message

Liao Shihua Feb. 20, 2023, 7:01 a.m. UTC 
This patch supports Zksh and Zksed extension. 
It includes instruction's machine description and built-in funtions. 

gcc/ChangeLog:

        * config/riscv/crypto.md (riscv_sm3p0_<mode>): Add ZKSED's and ZKSH's instructions.
        (riscv_sm3p1_<mode>):
        (riscv_sm4ed_<mode>):
        (riscv_sm4ks_<mode>):
        * config/riscv/riscv-builtins.cc (AVAIL): Add ZKSED's and ZKSH's AVAIL.
        * config/riscv/riscv-scalar-crypto.def (RISCV_BUILTIN): Add ZKSED's and ZKSH's built-in functions.

gcc/testsuite/ChangeLog:

        * gcc.target/riscv/zksed32.c: New test.
        * gcc.target/riscv/zksed64.c: New test.
        * gcc.target/riscv/zksh32.c: New test.
        * gcc.target/riscv/zksh64.c: New test.
