- [x] Implement refract using HLSL source in hlsl_intrinsics.h - [x] Implement the refract SPIR-V target built-in in clang/include/clang/Basic/BuiltinsSPIRV.td - [x] Add sema checks for refract to CheckSPIRVBuiltinFunctionCall in clang/lib/Sema/SemaSPIRV.cpp - [x] Add codegen for spv refract to EmitSPIRVBuiltinExpr in CGBuiltin.cpp - [x] Add codegen tests to clang/test/CodeGenHLSL/builtins/refract.hlsl - [x] Add spv codegen test to clang/test/CodeGenSPIRV/Builtins/refract.c - [x] Add sema tests to clang/test/SemaHLSL/BuiltIns/refract-errors.hlsl - [x] Add spv sema tests to clang/test/SemaSPIRV/BuiltIns/refract-errors.c - [x] Create the int_spv_refract intrinsic in IntrinsicsSPIRV.td - [x] In SPIRVInstructionSelector.cpp create the refract lowering and map it to int_spv_refract in SPIRVInstructionSelector::selectIntrinsic. - [x] Create SPIR-V backend test case in llvm/test/CodeGen/SPIRV/hlsl-intrinsics/refract.ll - [x] Check for what OpenCL support is needed.
