class angr.analyses.decompiler.optimization_passes.switch_default_case_duplicator.SwitchDefaultCaseDuplicator

Bases: OptimizationPass

For each switch-case construct (identified by jump tables), duplicate the default-case node when we detect situations where the default-case node is seemingly reused by edges outside the switch-case construct. This code reuse is usually caused by compiler code deduplication.

Ideally this pass should be implemented as an ISC optimization reversion.
