Relanding this PR now that https://github.com/llvm/llvm-project/pull/90503 has merged. with `FTAN` landing in [TargetLoweringBase.cpp:L1021](https://github.com/llvm/llvm-project/blob/main/llvm/lib/CodeGen/TargetLoweringBase.cpp#L1020C23-L1021C63 ) There is now a llvm tan intrinsic 32\64\128 Expand case for all llvm backends. In LLVM, the `llvm.experimental.constrained.cos` and `llvm.experimental.constrained.sin` intrinsics are used for performing cosine and sine calculations with additional constraints on floating-point operations. This behavior is expected for all floating-point math intrinsics. This change adds these constraints for the `tan` intrinsic. - `Builtins.td` - replace TanF128 with F16F128MathTemplate - `CGBuiltin.cpp` - map existing tan builtins to `tan` and `constrained_tan` intrinsic - `ConstrainedOps.def` map tan and constrained_tan to an ISDOpcode. resolves #91421 --------- Co-authored-by: Farzon Lotfi <farzon@farzon.com>
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.
