Peter Bindels 660a8982e7 LibM: Turn off builtins, fix tests & implementation ... While trying to port to Clang we found that the functions as implemented didn't actually work, and replacing them with a blatantly broken function also did not break the tests on the GCC build. It turns out we've been testing GCC's builtins by many tests. This removes the use of builtins for LibM's tests (so we test the whole function). It turns off the denormal test for scalbn (which was not implemented) and comments out the tgamma(0.5) test which is too inaccurate to be usable (and too complicated for me to fix). The gamma function was made accurate for all other test cases, and asin received two more layers of Taylor expansion to bring it within error margin for the tests.		2021-07-17 17:37:20 +02:00
