I just tried MLton with the "-verbose 2" flag and it seems to use "amd64Codegen" by default, on MacOS at least.

  Oh neat! I'm assuming then that C is the default for anything that doesn't have a specific backend for. I believe I heard that they had an x86 backend, but it was a pain to work with (maybe not as fast). Those are probably old concerns though, since their x86 64 backend must be more performant.
