[llvm-commits] [PATCH] Add float abi CL option for lli

[Amara Emerson]

I think that functionality would be a good thing to have now that our testing infrastructure is transitioning to hard float systems. However, that sounds like something that can be a separate patch to me. Having a runtime user configurable option would also be helpful in the (speculative) use case where the target system may not be the same one that lli is running on.

Since lli produces native code, wouldn't it be possible to detect what
system it is running on at runtime or maybe configure/cmake time?
