Constructor Details

This class inherits a constructor from Kumi::Core::Analyzer::Passes::PassBase

Instance Method Details

#run(errors) ⇒ Object

The loop lowering can hit a genuine “valid schema, unsupported construct” wall (e.g. cross(…) over a computed value). Those are raised as UnsupportedFeature; catch them here and surface as a clean, accumulated pass failure rather than letting PassManager re-raise them as an “internal compiler error (please report)”.
