You can take inspiration from anything in lld/test, but basically
either an assembly source (or multiple) passed through llvm-mc and
then lld, or a YAML file passed to yaml2obj (and then lld). From what
I see the Mach-O backend prefers YAML-style testing, but I don't think
that's a strict requirement.

Thanks,

Doesn't look like the test system works on windows?

Got it. 

Attached are both the testcase & the fix.
