Struct naga::valid::analyzer::Uniformity

pub struct Uniformity {
    pub non_uniform_result: Option<Handle<Expression>>,
    pub requirements: UniformityRequirements,
}

Uniform control flow characteristics.

Fields

non_uniform_result: Option<Handle<Expression>>

A child expression with non-uniform result.

This means, when the relevant invocations are scheduled on a compute unit, they have to use vector registers to store an individual value per invocation.

Whenever the control flow is conditioned on such value, the hardware needs to keep track of the mask of invocations, and process all branches of the control flow.

Any operations that depend on non-uniform results also produce non-uniform.

requirements: UniformityRequirements

If this expression requires uniform control flow, store the reason here.
