Added missing `pmadd<Packet2f>` for NEON. This leads to significant improvement in precision than previous `pmul+padd`, which was causing the `pcos` tests to fail. Also added an approx test with `std::sin`/`std::cos` since otherwise returning any `a^2+b^2=1` would pass. Modified `log(denorm)` tests. Denorms are not always supported by all systems (returns `::min`), are always flushed to zero on 32-bit arm, and configurably flush to zero on sse/avx/aarch64. This leads to inconsistent results across different systems (i.e. `-inf` vs `nan`). Added a check for existence and exclude ARM. Removed logistic exactness test, since scalar and vectorized versions follow different code-paths due to differences in `pexp` and `pmadd`, which result in slightly different values. For example, exactness always fails on arm, aarch64, and altivec. |
