> Any other tests that you would like to be added here? The consensus for the overall constexpr cmath design in Clang from https://github.com/llvm/llvm-project/pull/158048#issuecomment-3313760151 was that the constant evaluation would fail if `FENV_ACCESS` is ` ON` and the context is not one where the language requires constant evaluation. That way, dynamic rounding modes and the setting of `FE_INEXACT` at run time are observed. Once the logic is added, there should be a codegen test that expects the call to not be folded when `FENV_ACCESS` is `ON`. https://github.com/llvm/llvm-project/pull/199808 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
