| Item | Description |
|---|---|
| N |
[in] The number of temporary registers. |
Each register has space for a 32-bit four-component value. The total number of temporary and indexable-temporary registers must be less than or equal to 4096.
This instruction applies to the following shader stages:
| Vertex Shader | Geometry Shader | Pixel Shader |
|---|---|---|
| x | x | x |
This instruction is included to aid in debugging a shader in assembly; you cannot author a shader in assembly language using Shader Model 4.
Example
Here is an example.
dcl_temps 10; // Declare r0-r9
