Whether it should be rvintrin.h or riscv_intrinsic.h. The builtins in this patch are __builtin_riscv_orc_b_32 __builtin_riscv_orc_b_64 I've update the description summary to reflect this since it change during development. The Zbr patch uses the following without a 32/64 suffix. __builtin_riscv_crc32_b/w/d/q There's a difference because orc.b needs to be available for 32-bit on RV32 and RV64 per the spec so we have two builtins. crc32.b intrinsics in the spec are defined only for xlen so we have a single builtin.
