dcl_uav_raw (sm5 - asm)

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

dcl_uav_raw[_glc] dstUAV




[in] The UAV.



dstUAV is a u# register declared as a reference to an UnorderedAccessView of a Buffer, where the buffer appears as a simple 1D array of 32-bit untyped entries.

Operations performed on the memory may implicitly interpret the data as having a type.

The _glc flag means "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.
