WaveActiveAllEqual function
Returns true if the expression is the same for every active lane in the current wave (and thus uniform across it).
Syntax
<bool-type> WaveActiveAllEqual(
<type> expr
);
Parameters
-
expr
-
The expression to evaluate.
<type>can be a basic scalar, vector, or matrix type.
Return value
Returns true for each component of expr that is the same for every active lane in the current wave.
<bool-type> will be a scalar, vector, or matrix of bool, matching the dimensionality of the input <type>.
For instance, an input <type> of matrix<float, 4, 3> will result in a return <bool-type> of matrix<bool, 4, 3>.
Remarks
This function is supported from shader model 6.0 in all shader stages.
