-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.
