Extended Description

AVX512 versions of sin/cos/exp and similar intrinsics are missing. A reproducer is attached.

Reopening based on Hal's update. Maybe we can consider this down the road.

These intrinsics don't correspond to single instructions. They are part of Intel's SVML math library which ships with the Intel compiler.

Neither clang or gcc are likely to ever support these as it would require a math library to be created and released with the compiler.

FYI: Work on this is ongoing. I expect it to happen in the near future. See, for example, https://reviews.llvm.org/D24951
