SemanticDiff

Syntax

interface SemanticDiff {
  readonly interface: readonly string[];
  readonly resources: readonly string[];
  readonly constants: readonly string[];
  readonly controlFlow: readonly string[];
}

Description

Each entry is a fact line prefixed - (present in a, absent from b) or + (the reverse). When all four are empty the modules agree on everything this comparison inspects; isSemanticallyEqual performs that test.

Instance properties

interfaceread only readonly string[]

Entry-point signatures and the vertex attribute layout.

resourcesread only readonly string[]

Bind groups, std140/std430 struct layouts, and required capabilities.

constantsread only readonly string[]

Module consts, pipeline overrides, and the multiset of numeric literals in function bodies. A literal’s value is reported here and nowhere else, because the control-flow skeleton leaves it out, so changing a constant and changing the shape of the code around it land in different buckets.

controlFlowread only readonly string[]

Per-statement control-flow skeleton, one line per statement, addressed by path.
