[libc-commits] [libc] [libc][libm][GPU] Change CMake Logic to Allow Different Sets of Supported Vendor Functions (PR #66133)

https://github.com/AntonRydahl created https://github.com/llvm/llvm-project/pull/66133:

I made some detailed comparisons of the different versions of the C math functions available for GPUs. I found that some functions lower correctly on AMD GPU targets but not on NVIDIA targets, and vice versa. Therefore, I believe we should support different subsets of the HIP Math and CUDA Math APIs. By changing the CMake logic for `libc/src/libm` a bit, that is possible.

Let me know what you think of this.
