Members

Version

The shader version. See also D3D12_SHADER_VERSION_TYPE.

Creator

The name of the originator of the function.

Flags

A combination of D3DCOMPILE Constants that are combined by using a bitwise OR operation. The resulting value specifies shader compilation and parsing.

ConstantBuffers

The number of constant buffers for the function.

BoundResources

The number of bound resources for the function.

InstructionCount

The number of emitted instructions for the function.

TempRegisterCount

The number of temporary registers used by the function.

TempArrayCount

The number of temporary arrays used by the function.

DefCount

The number of constant defines for the function.

DclCount

The number of declarations (input + output) for the function.

TextureNormalInstructions

The number of non-categorized texture instructions for the function.

TextureLoadInstructions

The number of texture load instructions for the function.

TextureCompInstructions

The number of texture comparison instructions for the function.

TextureBiasInstructions

The number of texture bias instructions for the function.

TextureGradientInstructions

The number of texture gradient instructions for the function.

FloatInstructionCount

The number of floating point arithmetic instructions used by the function.

IntInstructionCount

The number of signed integer arithmetic instructions used by the function.

UintInstructionCount

The number of unsigned integer arithmetic instructions used by the function.

StaticFlowControlCount

The number of static flow control instructions used by the function.

DynamicFlowControlCount

The number of dynamic flow control instructions used by the function.

MacroInstructionCount

The number of macro instructions used by the function.

ArrayInstructionCount

The number of array instructions used by the function.

MovInstructionCount

The number of mov instructions used by the function.

MovcInstructionCount

The number of movc instructions used by the function.

ConversionInstructionCount

The number of type conversion instructions used by the function.

BitwiseInstructionCount

The number of bitwise arithmetic instructions used by the function.

MinFeatureLevel

A D3D_FEATURE_LEVEL-typed value that specifies the minimum Direct3D feature level target of the function byte code.

RequiredFeatureFlags

A value that contains a combination of one or more shader requirements flags; each flag specifies a requirement of the shader. A default value of 0 means there are no requirements. For a list of values, see ID3D12ShaderReflection::GetRequiresFlags.

Name

The name of the function.

FunctionParameterCount

The number of logical parameters in the function signature, not including the return value.

HasReturn

Indicates whether the function returns a value. TRUE indicates it returns a value; otherwise, FALSE (it is a subroutine).

Has10Level9VertexShader

Indicates whether there is a Direct3D 10Level9 vertex shader blob. TRUE indicates there is a 10Level9 vertex shader blob; otherwise, FALSE.

Has10Level9PixelShader

Indicates whether there is a Direct3D 10Level9 pixel shader blob. TRUE indicates there is a 10Level9 pixel shader blob; otherwise, FALSE.
