URL: https://github.com/llvm/llvm-project/commit/083d949f3800978c07260a0b8d6711c353d69e45 DIFF: https://github.com/llvm/llvm-project/commit/083d949f3800978c07260a0b8d6711c353d69e45.diff LOG: [HLSL] add sin library function This change exposes the sin library function for HLSL, excluding long, int, and long long doubles. Sin is supported for all scalar, vector, and matrix types. Long and long long double support is missing in this patch because those types don't exist in HLSL. Int is missing because the sin function only works on floating type arguments. The full documentation of the HLSL sin function is available here: https://docs.microsoft.com/en-us/windows/win32/direct3dhlsl/dx-graphics-hlsl-sin Reviewed By: python3kgae Differential Revision: https://reviews.llvm.org/D138161 Added: clang/test/CodeGenHLSL/builtins/sin.hlsl Modified: clang/lib/Headers/hlsl/hlsl_intrinsics.h Removed: ################################################################################ diff --git a/clang/lib/Headers/hlsl/hlsl_intrinsics.h b/clang/lib/Headers/hlsl/hlsl_intrinsics.h index addd22bd4d035..35891d80d5953 100644 --- a/clang/lib/Headers/hlsl/hlsl_intrinsics.h +++ b/clang/lib/Headers/hlsl/hlsl_intrinsics.h @@ -130,5 +130,34 @@ double3 cos(double3); __attribute__((clang_builtin_alias(__builtin_elementwise_cos))) double4 cos(double4); +// sin builtins +#ifdef __HLSL_ENABLE_16_BIT +__attribute__((clang_builtin_alias(__builtin_elementwise_sin))) half sin(half); +__attribute__((clang_builtin_alias(__builtin_elementwise_sin))) +half2 sin(half2); +__attribute__((clang_builtin_alias(__builtin_elementwise_sin))) +half3 sin(half3); +__attribute__((clang_builtin_alias(__builtin_elementwise_sin))) +half4 sin(half4); +#endif + +__attribute__((clang_builtin_alias(__builtin_elementwise_sin))) float +sin(float); +__attribute__((clang_builtin_alias(__builtin_elementwise_sin))) +float2 sin(float2); +__attribute__((clang_builtin_alias(__builtin_elementwise_sin))) +float3 sin(float3); +__attribute__((clang_builtin_alias(__builtin_elementwise_sin))) +float4 sin(float4); + +__attribute__((clang_builtin_alias(__builtin_elementwise_sin))) double +sin(double); +__attribute__((clang_builtin_alias(__builtin_elementwise_sin))) +double2 sin(double2); +__attribute__((clang_builtin_alias(__builtin_elementwise_sin))) +double3 sin(double3); +__attribute__((clang_builtin_alias(__builtin_elementwise_sin))) +double4 sin(double4); + } // namespace hlsl #endif //_HLSL_HLSL_INTRINSICS_H_ diff --git a/clang/test/CodeGenHLSL/builtins/sin.hlsl b/clang/test/CodeGenHLSL/builtins/sin.hlsl new file mode 100644 index 0000000000000..73cb1b7775b0c --- /dev/null +++ b/clang/test/CodeGenHLSL/builtins/sin.hlsl @@ -0,0 +1,56 @@ +// RUN: %clang_cc1 -std=hlsl2021 -finclude-default-header -x hlsl -triple \ +// RUN: dxil-pc-shadermodel6.3-library %s -fnative-half-type \ +// RUN: -emit-llvm -disable-llvm-passes -O3 -o - | FileCheck %s +// RUN: %clang_cc1 -std=hlsl2021 -finclude-default-header -x hlsl -triple \ +// RUN: dxil-pc-shadermodel6.3-library %s -emit-llvm -disable-llvm-passes \ +// RUN: -D__HLSL_ENABLE_16_BIT -o - | FileCheck %s --check-prefix=NO_HALF + +// CHECK: define noundef half @ +// CHECK: call half @llvm.sin.f16( +// NO_HALF: define noundef float @"?test_sin_half@@YA$halff@$halff@@Z"( +// NO_HALF: call float @llvm.sin.f32( +half test_sin_half ( half p0 ) { + return sin ( p0 ); +} +// CHECK: define noundef <2 x half> @ +// CHECK: call <2 x half> @llvm.sin.v2f16 +// NO_HALF: define noundef <2 x float> @"?test_sin_float2@@YAT?$__vector@M$01@__clang@@T12@@Z"( +// NO_HALF: call <2 x float> @llvm.sin.v2f32( +half2 test_sin_half2 ( half2 p0 ) { + return sin ( p0 ); +} +// CHECK: define noundef <3 x half> @ +// CHECK: call <3 x half> @llvm.sin.v3f16 +// NO_HALF: define noundef <3 x float> @"?test_sin_float3@@YAT?$__vector@M$02@__clang@@T12@@Z"( +// NO_HALF: call <3 x float> @llvm.sin.v3f32( +half3 test_sin_half3 ( half3 p0 ) { + return sin ( p0 ); +} +// CHECK: define noundef <4 x half> @ +// CHECK: call <4 x half> @llvm.sin.v4f16 +// NO_HALF: define noundef <4 x float> @"?test_sin_float4@@YAT?$__vector@M$03@__clang@@T12@@Z"( +// NO_HALF: call <4 x float> @llvm.sin.v4f32( +half4 test_sin_half4 ( half4 p0 ) { + return sin ( p0 ); +} + +// CHECK: define noundef float @ +// CHECK: call float @llvm.sin.f32( +float test_sin_float ( float p0 ) { + return sin ( p0 ); +} +// CHECK: define noundef <2 x float> @ +// CHECK: call <2 x float> @llvm.sin.v2f32 +float2 test_sin_float2 ( float2 p0 ) { + return sin ( p0 ); +} +// CHECK: define noundef <3 x float> @ +// CHECK: call <3 x float> @llvm.sin.v3f32 +float3 test_sin_float3 ( float3 p0 ) { + return sin ( p0 ); +} +// CHECK: define noundef <4 x float> @ +// CHECK: call <4 x float> @llvm.sin.v4f32 +float4 test_sin_float4 ( float4 p0 ) { + return sin ( p0 ); +} _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
