Commit Message

Liao Shihua Dec. 5, 2023, 12:03 p.m. UTC
  This patch adds C intrinsics for Bitmanip Extension.
RISCV_BUILTIN_NO_PREFIX is a new riscv_builtin_description like RISCV_BUILTIN.
But it uses CODE_FOR_##INSN rather than CODE_FOR_riscv_##INSN.
Some of the instructions are different to spec, see https://github.com/riscv-non-isa/riscv-c-api-doc/pull/59 for details.

gcc/ChangeLog:

        * config.gcc: Add riscv_bitmanip.h
        * config/riscv/riscv-builtins.cc (AVAIL): New AVAIL.
        (RISCV_BUILTIN_NO_PREFIX): new riscv_builtin_description.
        * config/riscv/riscv-ftypes.def (2): New function type.
        * config/riscv/riscv-scalar-crypto.def (RISCV_BUILTIN_NO_PREFIX):New builtins.
        * config/riscv/riscv_bitmanip.h: New file.

gcc/testsuite/ChangeLog:

        * gcc.target/riscv/scalar_bitmanip_intrinsic-1.c: New test.
        * gcc.target/riscv/scalar_bitmanip_intrinsic-2.c: New test.
