Is GIMPLE any worse or better in this regards?
- jcranmer 7y agoI don't have much experience with GCC innards, but after doing a quick test [1], it seems GCC is as bad as clang in terms of not supporting STDC FENV_ACCESS, so I suspect the answer is that it's pretty much the same. It looks like the only major compiler that actually supports IEEE 754 correctly is icc. MSVC, gcc, and clang all optimize floating-point operations without considering if the dynamic environment is the same. [1] https://godbolt.org/z/x2ERVM https://godbolt.org/z/x2ERVM
