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
Number of floating point arithmetic instructions used.
IntInstructionCount
Number of signed integer arithmetic instructions used.
UintInstructionCount
Number of unsigned integer arithmetic instructions used.
StaticFlowControlCount
Number of static flow control instructions used.
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.
