[PATCH] D100118: [clang] RFC Support new builtin __arithmetic_fence to control floating point optimization, and new clang option fprotect-parens

[Melanie Blower via Phabricator via llvm-commits]

mibintc updated this revision to Diff 337881.
mibintc retitled this revision from "[clang] RFC Support new builtin __arithmetic_fence to control floating point optiization" to "[clang] RFC Support new builtin __arithmetic_fence to control floating point optimization, and new clang option fprotect-parens".
mibintc added a comment.

This is a minor change with only formatting changes, this patch is not yet ready for review, only discussion. 
Together with the llvm parent patch, this simple program can now run end-to-end

  clang -c -ffast-math test.c
  
  float addF(float x, float y) {
    return __arithmetic_fence(x + y);
  }
