## Message

```
add bcmp implementation as LLVM 9 now emits those

The optimizer will now convert calls to memcmp into a calls to bcmp
in some circumstances. Users who are building freestanding code (not
depending on the platform’s libc) without specifying -ffreestanding may
need to either pass -fno-builtin-bcmp, or provide a bcmp function.
