URL: https://github.com/llvm/llvm-project/commit/c7afb698caf00f0ad0b479f7d2869c119aa3482e DIFF: https://github.com/llvm/llvm-project/commit/c7afb698caf00f0ad0b479f7d2869c119aa3482e.diff LOG: [AMDGPU] Avoid calling copyFastMathFlags in wrong context Calling Instruction::copyFastMathFlags() assumes the caller is FPMathOperator. Avoid calling the function for instructions that are not instances of FPMathOperator.
