partially fixes #99151 ### Changes * Implemented `radians` clang builtin * Linked `radians` clang builtin with `hlsl_intrinsics.h` * Added sema checks for `radians` to `CheckHLSLBuiltinFunctionCall` in `SemaChecking.cpp` * Add codegen for `radians` to `EmitHLSLBuiltinExpr` in `CGBuiltin.cpp` * Add codegen tests to `clang/test/CodeGenHLSL/builtins/radians.hlsl` * Add sema tests to `clang/test/SemaHLSL/BuiltIns/radians-errors.hlsl` ### Related PRs * [[DXIL] Add radians intrinsic #110616](https://github.com/llvm/llvm-project/pull/110616) * [[SPIRV] Add radians intrinsic #110800](https://github.com/llvm/llvm-project/pull/110800) >From be88a591ed220714b21b73e34406bfcdb866ac17 Mon Sep 17 00:00:00 2001 From: Adam Yang <hanby...@microsoft.com> Date: Wed, 2 Oct 2024 01:21:19 -0700 Subject: [PATCH] Added radians to clang --- clang/include/clang/Basic/Builtins.td | 6 +++ clang/lib/CodeGen/CGBuiltin.cpp | 8 +++ clang/lib/CodeGen/CGHLSLRuntime.h | 1 + clang/lib/Headers/hlsl/hlsl_intrinsics.h | 30 +++++++++++ clang/lib/Sema/SemaHLSL.cpp | 1 + clang/test/CodeGenHLSL/builtins/radians.hlsl | 54 +++++++++++++++++++ .../SemaHLSL/BuiltIns/radians-errors.hlsl | 27 ++++++++++ 7 files changed, 127 insertions(+) create mode 100644 clang/test/CodeGenHLSL/builtins/radians.hlsl create mode 100644 clang/test/SemaHLSL/BuiltIns/radians-errors.hlsl diff --git a/clang/include/clang/Basic/Builtins.td b/clang/include/clang/Basic/Builtins.td index 8090119e512fbb..09b130e0def0d7 100644 --- a/clang/include/clang/Basic/Builtins.td +++ b/clang/include/clang/Basic/Builtins.td @@ -4788,6 +4788,12 @@ def HLSLStep: LangBuiltin<"HLSL_LANG"> { let Prototype = "void(...)";
