Public Member Functions
SetTheory ()
Create a SetTheory instance with only the standard operators.
void addExpander (StringRef ClassName, std::unique_ptr< Expander >)
addExpander - Add an expander for Records with the named super class.
void addFieldExpander (StringRef ClassName, StringRef FieldName)
addFieldExpander - Add an expander for ClassName that simply evaluates FieldName in the Record to get the set elements.
void addOperator (StringRef Name, std::unique_ptr< Operator >)
addOperator - Add a DAG operator.
void evaluate (const Init *Expr, RecSet &Elts, ArrayRef< SMLoc > Loc)
evaluate - Evaluate Expr and append the resulting set to Elts.
template
void evaluate (Iter begin, Iter end, RecSet &Elts, ArrayRef< SMLoc > Loc)
evaluate - Evaluate a sequence of Inits and append to Elts.

addFieldExpander - Add an expander for ClassName that simply evaluates FieldName in the Record to get the set elements.

That is all that is needed for a class like:

class Set { dag Elts = d; }

void llvm::SetTheory::evaluate ( Iter begin, Iter end, RecSet & Elts, ArrayRef< SMLoc > Loc ) inline

evaluate - Evaluate a sequence of Inits and append to Elts.

◆ expand()

expand - Expand a record into a set of elements if possible.

Return a pointer to the expanded elements, or NULL if Set cannot be expanded further.
