Members

Version

The Shader version, as an encoded UINT that corresponds to a shader model, such as "ps_5_0". Version describes the program type, a major version number, and a minor version number. The program type is a D3D12_SHADER_VERSION_TYPE enumeration constant. Version is decoded in the following way:

• Program type = (Version & 0xFFFF0000) >> 16
• Major version = (Version & 0x000000F0) >> 4
• Minor version = (Version & 0x0000000F)

Creator

The name of the originator of the shader.

Flags

Shader compilation/parse flags.

ConstantBuffers

The number of shader-constant buffers.

BoundResources

The number of resource (textures and buffers) bound to a shader.

InputParameters

The number of parameters in the input signature.

OutputParameters

The number of parameters in the output signature.

InstructionCount

The number of intermediate-language instructions in the compiled shader.

TempRegisterCount

The number of temporary registers in the compiled shader.

TempArrayCount

Number of temporary arrays used.

DefCount

Number of constant defines.

DclCount

Number of declarations (input + output).

TextureNormalInstructions

Number of non-categorized texture instructions.

TextureLoadInstructions

Number of texture load instructions

TextureCompInstructions

Number of texture comparison instructions

TextureBiasInstructions

Number of texture bias instructions

TextureGradientInstructions

Number of texture gradient instructions.

FloatInstructionCount

DynamicFlowControlCount

Number of dynamic flow control instructions used.

MacroInstructionCount

Number of macro instructions used.

ArrayInstructionCount

Number of array instructions used.

CutInstructionCount

Number of cut instructions used.

EmitInstructionCount

Number of emit instructions used.

GSOutputTopology

The D3D_PRIMITIVE_TOPOLOGY-typed value that represents the geometry shader output topology.

GSMaxOutputVertexCount

Geometry shader maximum output vertex count.

InputPrimitive

The D3D_PRIMITIVE-typed value that represents the input primitive for a geometry shader or hull shader.

PatchConstantParameters

Number of parameters in the patch-constant signature.

cGSInstanceCount

Number of geometry shader instances.

cControlPoints

Number of control points in the hull shader and domain shader.

HSOutputPrimitive

The D3D_TESSELLATOR_OUTPUT_PRIMITIVE-typed value that represents the tessellator output-primitive type.

HSPartitioning

The D3D_TESSELLATOR_PARTITIONING-typed value that represents the tessellator partitioning mode.

TessellatorDomain

The D3D_TESSELLATOR_DOMAIN-typed value that represents the tessellator domain.

cBarrierInstructions

Number of barrier instructions in a compute shader.

cInterlockedInstructions

Number of interlocked instructions in a compute shader.

cTextureStoreInstructions

Number of texture writes in a compute shader.

Remarks

A shader is written in HLSL and compiled into an intermediate language by the HLSL compiler. The shader description returns information about the compiled shader. To get a shader description, call ID3D12ShaderReflection::GetDesc.
