  UINT32 instructionCount
);

Parameters

instructionCount

Type: UINT32

An approximate instruction count of the associated shader.

Remarks

The instruction count may be set according to the number of instructions in the shader. This information is used as a hint when rendering extremely large images. Calling this API is optional, but it may improve performance if you provide an accurate number.

Note  Instructions that occur in a loop should be counted according to the number of loop iterations.
