[cfe-dev] How do I pass options to llc through clang?

[Reid Kleckner]

Try to find the Clang driver option, as these are the supported interface.
In this case, I think -fno-honor-nans is what you want.

You can pass options through to LLVM with -mllvm, but this is fragile, best
effort, and can easily break.
