Inherits:
Seafoam::Pass show all
Defined in:
lib/seafoam/passes/fallback.rb

Overview

The fallback pass always applies, and adds some basic properties. Works for example with Truffle AST and call graphs, but also means anyone can emit a graph with ‘label’ properties and we can do something useful with it.
