URL: https://github.com/llvm/llvm-project/commit/e4259b583c92244e2c49c664fad0fbc1bdaa800b DIFF: https://github.com/llvm/llvm-project/commit/e4259b583c92244e2c49c664fad0fbc1bdaa800b.diff LOG: [Float2Int] Pre-commit test for SIToFP/UIToFP ConstantRange bug. NFC The range for these operations is being constructed without the maximum value for the range due to an incorrect usage of the ConstantRange constructor. This causes Float2Int to think the range for 'uitofp i1' only contains 0 instead of 0 and 1.
