What exactly is the situation with support for -frounding-math in llvm-gcc/clang? I ask because we are seeing regressions in the ppl 0.11.2 testsuite when compiling with either llvm-gcc or clang from Xcode 4.1 as well as clang svn. The ppl developers seem to be seeing warnings to the effect...

clang: warning: argument unused during compilation: '-frounding-math'

in their builds.

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.
