* config/riscv/crypto.md (riscv_sha256sig0_<mode>): Add ZKNH's
instructions.
(riscv_sha256sig1_<mode>):
(riscv_sha256sum0_<mode>):
(riscv_sha256sum1_<mode>):
(riscv_sha512sig0h):
(riscv_sha512sig0l):
(riscv_sha512sig1h):
(riscv_sha512sig1l):
(riscv_sha512sum0r):
(riscv_sha512sum1r):
(riscv_sha512sig0):
(riscv_sha512sig1):
(riscv_sha512sum0):
(riscv_sha512sum1):
* config/riscv/riscv-builtins.cc (AVAIL): And ZKNH's AVAIL.
* config/riscv/riscv-scalar-crypto.def (RISCV_BUILTIN): And ZKNH's
built-in functions.
(DIRECT_BUILTIN):
gcc/testsuite/ChangeLog:
* gcc.target/riscv/zknh-sha256.c: New test.
