◆ addPartialTaint()

ProgramStateRef clang::ento::taint::addPartialTaint ( ProgramStateRef  State,
SymbolRef  ParentSym,
const SubRegion SubRegion,
TaintTagType  Kind = TaintTagGeneric 
)

Create a new state in a which a sub-region of a given symbol is tainted.

This might be necessary when referring to regions that can not have an individual symbol, e.g. if they are represented by the default binding of a LazyCompoundVal.
