Edit

break_comp - ps

  • Article

Break out of the current loop at the nearest endloop - ps or endrep - ps, based on a per-component comparison.

Syntax

break_comp src0, src1

 

Where:

  • _comp is a scalar (or single) 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 if selecting a single component.

  • src1 is a source register. Replicate swizzle is required if selecting a single component.

Remarks

This instruction is supported in the following versions.

Pixel shader versions 1_1 1_2 1_3 1_4 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;
