URL: https://github.com/llvm/llvm-project/commit/3a18f267236351873a4c7821735c70b0790e4919 DIFF: https://github.com/llvm/llvm-project/commit/3a18f267236351873a4c7821735c70b0790e4919.diff LOG: [CostModel] add tests for FP maximum; NFC These min/max intrinsics are not handled in the basic implementation and probably not handled in target-specific overrides either.
