Hi, I am writing some code that relies heavily on the use of constexpr math functions to do calculations at compile time. The ability to do these calculations at compile time is essential for the performance of the library. Currently gcc is the only compiler that supports compile time math operations such as "constexpr sin" and "constexpr cos". And it seems that by doing so gcc is technically not conforming to the standard. See here: https://stackoverflow.com/questions/27744079/is-it-a-conforming-compiler-extension-to-treat-non-constexpr-standard-library-fu I am concerned that if I go down this path and become dependent on these non-conforming features, support for this functionality may be dropped in a future release of gcc. Is there any way I can get more information on plans for future support of constexpr math functions in gcc? Thanks, Tim
