* Fix failures in libm's lround_test after clang 12 importDimitry Andric2021-06-221-6/+1
| | | | | | | | | | | | | | | | | | | | | It turned out that the (type)DTYPE_MAX conversions at the top of s_lround.c are now emitted as cvtsi2sd instructions, at least on SSE capable CPUs. This caused the FE_INEXACT flag to always be set, at least for the double and float variants. Under clang 11, the whole INRANGE() comparisons were still optimized away, but this has "improved" in clang 12, due to stricter adherence to the -ffp-exception-behavior=maytrap compiler flag. To avoid run-time integer to float conversions, use static constants instead, so they are computed at compile time, and the INRANGE() statements are optimized away again, if applicable. While here, use an integer instead of a floating type to store the test results in lround_test.c, as this is more appropriate, and we can also drop the volatile hack.

* Allow lib/msun/logarithm_test to pass on ld128 platformsAlex Richardson2021-04-201-1/+17
| | | | | | | | | | | | For some reason the ld128 log1pl() implementation is less accurate than logl(), but does at least guarantee precision >= the ld80 implementation. Mark log1p_accuracy_tests as XFAIL for ld128 and increase the log1p tolerance to the ld80 equivalent in accuracy_tests to avoid losing test coverage for the other functions.
