[X86][LoopVectorize] Add support for arc and hyperbolic trig functions (#99383)
This change is part 2 x86 Loop Vectorization of : https://github.com/llvm/llvm-project/pull/96222 It also has veclib call loop vectorization hence the test cases in `llvm/test/Transforms/LoopVectorize/X86/veclib-calls.ll` finally the last pr missed tests for `llvm/test/CodeGen/X86/fp-strict-libcalls-msvc32.ll` and `llvm/test/CodeGen/X86/vec-libcalls.ll` so added those aswell. No evidence was found for arc and hyperbolic trig glibc vector math functions https://github.com/lattera/glibc/blob/master/sysdeps/x86/fpu/bits/math-vector.h so no new `_ZGVbN2v_*` and `_ZGVdN4v_*` . So no new tests in `llvm/test/Transforms/LoopVectorize/X86/libm-vector-calls-VF2-VF8.ll` Also no new svml and no new tests to: `llvm/test/Transforms/LoopVectorize/X86/svml-calls.ll` There was not enough evidence that there were svml arc and hyperbolic trig vector implementations, Documentation was scarces so looked at test cases in [numpy](https://github.com/numpy/SVML/blob/32bf2a98420762a63ab418aaa0a7d6e17eb9627a/linux/avx512/svml_z0_acos_d_la.s#L8). Someone with more experience with svml should investigate. ## Note amd libm doesn't have a vector hyperbolic sine api hence why youi might notice there are no tests for `sinh`. ## History This change is part of https://github.com/llvm/llvm-project/issues/87367's investigation on supporting IEEE math operations as intrinsics. Which was discussed in this RFC: https://discourse.llvm.org/t/rfc-all-the-math-intrinsics/78294 This change adds loop vectorization for `acos`, `asin`, `atan`, `cosh`, `sinh`, and `tanh`. resolves #70079 resolves #70080 resolves #70081 resolves #70083 resolves #70084 resolves #95966
