https://github.com/V-FEXrt created https://github.com/llvm/llvm-project/pull/115902
Resolves https://github.com/llvm/llvm-project/issues/99160
- [x] Implement `WaveActiveAnyTrue` clang builtin,
- [x] Link `WaveActiveAnyTrue` clang builtin with `hlsl_intrinsics.h`
- [x] Add sema checks for `WaveActiveAnyTrue` to `CheckHLSLBuiltinFunctionCall` in `SemaChecking.cpp`
- [x] Add codegen for `WaveActiveAnyTrue` to `EmitHLSLBuiltinExpr` in `CGBuiltin.cpp`
- [x] Add codegen tests to `clang/test/CodeGenHLSL/builtins/WaveActiveAnyTrue.hlsl`
- [x] Add sema tests to `clang/test/SemaHLSL/BuiltIns/WaveActiveAnyTrue-errors.hlsl`
- [x] Create the `int_dx_WaveActiveAnyTrue` intrinsic in `IntrinsicsDirectX.td`
- [x] Create the `DXILOpMapping` of `int_dx_WaveActiveAnyTrue` to `113` in `DXIL.td`
- [x] Create the `WaveActiveAnyTrue.ll` and `WaveActiveAnyTrue_errors.ll` tests in `llvm/test/CodeGen/DirectX/`
- [x] Create the `int_spv_WaveActiveAnyTrue` intrinsic in `IntrinsicsSPIRV.td`
- [x] In SPIRVInstructionSelector.cpp create the `WaveActiveAnyTrue` lowering and map it to `int_spv_WaveActiveAnyTrue` in `SPIRVInstructionSelector::selectIntrinsic`.
- [x] Create SPIR-V backend test case in `llvm/test/CodeGen/SPIRV/hlsl-intrinsics/WaveActiveAnyTrue.ll`
