================ Comment at: clang/include/clang/Basic/BuiltinsRISCV.def:21 TARGET_BUILTIN(__builtin_riscv_orc_b_64, "WiWi", "nc", "zbb,64bit") -TARGET_BUILTIN(__builtin_riscv_clz_32, "ZiZi", "nc", "zbb") +TARGET_BUILTIN(__builtin_riscv_clz_32, "ZiZi", "nc", "zbb|experimental-zbpbo") TARGET_BUILTIN(__builtin_riscv_clz_64, "WiWi", "nc", "zbb,64bit") ---------------- What's preventing __builtin_riscv_clz_32 from being used on rv64 with Zbpbo? I think you need to add it to isRISCV32Builtin in SemaChecking.cpp but you'll also need to check that Zbb isn't enabled.
