ieq (sm4 - asm)
Component-wise vector integer equality comparison.
| ieq dest[.mask], src0[.swizzle], src1[.swizzle] |
|---|
| Item | Description |
|---|---|
| dest |
[in] The address of the result of the operation. |
| src0 |
[in] The value to compare with src1. |
| src1 |
[in] The value to compare with src0. |
Remarks
This instruction performs the integer comparison (src0 == src1) for each component, and writes the result to dest.
If the comparison is true, then 0xFFFFFFFF is returned for that component. Otherwise 0x0000000 is returned
This instruction applies to the following shader stages:
| Vertex Shader | Geometry Shader | Pixel Shader |
