dcl_uav_typed (sm5 - asm)

Declare an unordered access view (UAV) for use by a shader.

Remarks

dstUAV is a u# register being declared as a reference to an UnorderedAccessView that must be bound to UAV slot # at the API.

The dimension must be buffer, Texture1D, Texture1DArray, Texture2D, Texture2DArray, or Texture3D. This indicates how many dimensions any instructions accessing the UAV are providing: 1 (Texture1D, Buffer), 2 (Texture1DArray, Texture2D) or 3 (Texture2DArray, Texture3D).

Type is {UNORM,SNORM,UINT,SINT,FLOAT}. Operations done with the declared u# must be compatible with the type declared here, and the UAV bound to slot # must also have the same type.

The _glc flag stands for "globally coherent". The absence of _glc means the UAV is being declared only as "group coherent" in the compute shader, or "locally coherent" in a single pixel shader invocation.

This instruction applies to the following shader stages:

Because UAVs are available at all shader stages for Direct3D 11.1, this instruction applies to all shader stages for the Direct3D 11.1 runtime, which is available starting with Windows 8.

Minimum Shader Model

This instruction is supported in the following shader models:
