This change is part of this proposal: https://discourse.llvm.org/t/rfc-all-the-math-intrinsics/78294 Based on example PR #96222 and fix PR #101268, with some differences due to 2-arg intrinsic and intermediate refactor (RuntimeLibCalls.cpp). - Add llvm.experimental.constrained.atan2 - Intrinsics.td, ConstrainedOps.def, LangRef.rst - Add to ISDOpcodes.h and TargetSelectionDAG.td, connect to intrinsic in BasicTTIImpl.h, and LibFunc_ in SelectionDAGBuilder.cpp - Update LegalizeDAG.cpp, LegalizeFloatTypes.cpp, LegalizeVectorOps.cpp, and LegalizeVectorTypes.cpp - Update isKnownNeverNaN in SelectionDAG.cpp - Update SelectionDAGDumper.cpp - Update libcalls - RuntimeLibcalls.def, RuntimeLibcalls.cpp - TargetLoweringBase.cpp - Expand for vectors, promote f16 - X86ISelLowering.cpp - Expand f80, promote f32 to f64 for MSVC Part 4 for Implement the atan2 HLSL Function #70096.
This directory contains test cases for individual source features of LLVM. It is designed to make sure that the major components of LLVM support all of the features of LLVM, for very small examples. Entire programs should not go here. Regression tests for individual bug fixes should go into the test/Regression dir.
