spatel added a comment. Thanks for the clarification!
If I'm reading this properly, we should make the same kind of change as in https://reviews.llvm.org/D39481 ('c' -> 'e') for most of complex.h. Ie, the standard allows errno-setting, and it's (unfortunately for optimization) even more clearly stated in the newer additions to the standards. We can leave these functions as always constant ('c') because they don't actually do any math and therefore won't set errno: cimag ( http://en.cppreference.com/w/c/numeric/complex/cimag ) creal ( http://en.cppreference.com/w/c/numeric/complex/creal ) cproj ( http://en.cppreference.com/w/c/numeric/complex/cproj ) conj (http://en.cppreference.com/w/c/numeric/complex/conj ) https://reviews.llvm.org/D39611 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
