ge (sm4 - asm)
Component-wise vector floating point greater-than-or-equal comparison.
| ge dest[.mask], [-]src0[_abs][.swizzle], [-]src1[_abs][.swizzle] |
|---|
| Item | Description |
|---|---|
| dest |
[in] The address of the result of the operation. |
| src0 |
[in] The component to compare to src1. |
| src1 |
[in] The component to compare to src0. |
Remarks
Performs the float 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.
Denorms are flushed before comparison, and original source registers are untouched. +0 equals -0. Comparison with NaN returns false.
This instruction applies to the following shader stages:
| Vertex Shader | Geometry Shader | Pixel Shader |
