With https://github.com/llvm/llvm-project/pull/112852, we claimed that llvm.minnum and llvm.maxnum should treat +0.0>-0.0, while libc doesn't require fmin(3)/fmax(3) for it. To make llvm.minnum/llvm.maxnum easy to use, we define the builtin functions for them, include __builtin_elementwise_minnum __builtin_elementwise_maxnum All of them support _Float16, __bf16, float, double, long double.
