Yes, I have actually run into these. -fexpensive-optimizations: http://www.ks.uiuc.edu/Research/phi/ -minline-all-stringops: povray At the latter, I would consider possibly harmful since Clang > will create calls to memset() etc in some situations. > As a practical matter, I'm adding these so that I can continue to build software that used to build. They're marked clang_ignored_[fm]_Group so that we can find which flags aren't implemented. I'm not sure what you're saying -- are you arguing that implementing -minline-all-stringops is dangerous, or that silently ignoring -minline-all-stringops is dangerous? Nick
