Variants

Temp

A temporary register (r<n>).

Input

An input register (v<n>).

Output

An output register (o<n>).

IndexableTemp

An indexable temporary (x<n>[i]).

Constant

A constant buffer register (cb<slot>[row]).

Immediate

An immediate operand (l(...)), its values in Operand::immediate.

Texture

A shader resource view (t<n>).

Sampler

A sampler (s<n>).

Null

The null register (null), a destination that discards its result.

Uav

An unordered-access view (u<n>).

ImmediateBuffer

The immediate constant buffer (icb[n]), its rows the program’s own.

PrimitiveId

vPrim, the primitive id input.

InputCoverage

vCoverage, the input coverage mask.

OutputDepth

oDepth.

OutputDepthGreaterEqual

oDepthGE, a depth output that is at least the rasterized depth.

OutputDepthLessEqual

oDepthLE, a depth output that is at most the rasterized depth.

OutputCoverage

oMask, the coverage output.

OutputStencilRef

oStencilRef, the stencil reference output.

GroupSharedMemory

g<n>, thread-group shared memory.

ThreadId

vThreadID, vThreadGroupID, vThreadIDInGroup and vThreadIDInGroupFlattened, a compute program’s ids.

ThreadGroupId

vThreadGroupID.

ThreadIdInGroup

vThreadIDInGroup.

ThreadIdInGroupFlattened

vThreadIDInGroupFlattened.

OutputControlPointId

vOutputControlPointID, vForkInstanceID, vJoinInstanceID: a hull program’s phase numbers.

ForkInstanceId

vForkInstanceID, a hull program’s fork phase instance.

JoinInstanceId

vJoinInstanceID, a hull program’s join phase instance.

InputControlPoint

vicp[point][register]: an input control point of a hull or domain program.

OutputControlPoint

vocp[point][register]: an output control point a hull program’s patch-constant phases read.

InputPatchConstant

vpc[register]: a patch constant a domain program reads (or a hull program’s join phase).

InputDomainPoint

vDomain: a domain program’s location in its patch.

Stream

m<n>: a geometry program’s output stream.

GsInstanceId

vGSInstanceID.
