Resolves #99114. Tasks completed: - Implement `faceforward` in `hlsl_intrinsics.h`/`hlsl_intrinsic_helpers.h` - Implement `faceforward` SPIR-V target builtin in `clang/include/clang/Basic/BuiltinsSPIRV.td` - Add a SPIR-V fast path in `hlsl_intrinsic_helpers.h` - Add sema checks for `faceforward` to `CheckSPIRVBuiltinFunctionCall` in `clang/lib/Sema/SemaSPIRV.cpp` - Add codegen for SPIR-V `faceforward` builtin to `EmitSPIRVBuiltinExpr` in `SPIR.cpp` - Add HLSL codegen tests to `clang/test/CodeGenHLSL/builtins/faceforward.hlsl` - Add SPIRV builtin codegen tests to `clang/test/CodeGenSPIRV/Builtins/faceforward.c` - Add sema tests to `clang/test/SemaHLSL/BuiltIns/faceforward-errors.hlsl` - Add spirv sema tests to `clang/test/SemaSPIRV/BuiltIns/faceforward-errors.c` - Create the `int_spv_faceforward` intrinsic in `IntrinsicsSPIRV.td` - In `SPIRVInstructionSelector.cpp` create the `faceforward` lowering and map it to `int_spv_faceforward` in `SPIRVInstructionSelector::selectIntrinsic` - Create SPIR-V backend test case in `llvm/test/CodeGen/SPIRV/hlsl-intrinsics/faceforward.ll` Incomplete tasks: - Create SPIR-V backend test case in `llvm/test/CodeGen/SPIRV/opencl/faceforward.ll` - Not applicable because the OpenCL SPIR-V extended instruction set does not include a `faceforward` function Follow-up tasks: - Implement pattern matching for `faceforward` in `SPIRVCombine.td` and `SPIRVPreLegalizerCombiner.cpp` - In `faceforward.ll`, change `--target-env spv1.4` to `vulkan1.3` and update the test accordingly once [#136344](https://github.com/llvm/llvm-project/issues/136344) has been resolved
