break_comp (Vertex Shader)
Conditionally break out of the current loop at the nearest endloop or endrep.
Syntax
Where:
- _comp is a comparison between the two source registers. It can be one of the following:
| Syntax | Comparison |
|---|
| _gt | Greater than |
| _lt | Less than |
| _ge | Greater than or equal |
| _le | Less than or equal |
| _eq | Equal to |
| _ne | Not equal to |
- src0 is a source register. Replicate swizzle is required to select a single component.
- src1 is a source register. Replicate swizzle is required to select a single component.
Remarks
This instruction is supported in the following versions.
| Vertex shader versions | 1_1 | 2_0 | 2_x | 2_sw | 3_0 | 3_sw |
|---|
| break_comp | | | x | x | x | x |
|---|
When the comparison is true, it breaks out of the current loop, as shown.
if (src0 comparison src1)
jump to the corresponding endloop or endrep instruction;
