Member Function Documentation

analyze()

MemoryAliasAnalyzer::AliasingResult FalseAliasAnalyzer::analyze ( DataDependenceGraph &  ddg, const ProgramOperation &  pop1, const ProgramOperation &  pop2, MoveNodeUse::BBRelation  bbInfo  )

overridevirtual

checks whether mem adderesses alias. As this is fake, always returns false.

Returns

always ALIAS_FALSE

Implements MemoryAliasAnalyzer.
