Thanks in advance for any clarifications on the status of -frounding-math in the llvm based compilers.
Not supported, and I don't know of anyone who plans on working on it (or FENV_ACCESS) in the near future.
Eli, Is this the same situation with llvm-gcc? I don't see the warnings from llvm-gcc but we do see the same failures in ppl's testsuite. Is this a case of llvm-gcc silently not supporting -frounding-math?
Yep, llvm-gcc just accepts and ignores the flag.
