The test snip mentioned in my previous mail if from openFOAM application, it fails at runtime because of unconditional FDIV.
People are working on supporting the floating point environment on LLVM at the moment, but it looks like that program will need changing too. You're only allowed to rely on exception state if you have "#pragma STDC FENV_ACCESS ON" which it doesn't seem to.
Cheers.
Tim.
