dcl_immediateConstantBuffer (sm4 - asm)

Declares a shader immediate-constant buffer.

dcl_immediateConstantBuffer value(s)

 

value(s)

[in] The buffer must contain at least one value, but not more than 4096 values.

A shader is allowed one immediate-constant buffer. An immediate-constant buffer is accessed just like a constant buffer with dynamic indexing.

This instruction applies to the following shader stages:
