Member Function Documentation

◆ addExpander()

void SetTheory::addExpander	(	StringRef	ClassName,
		std::unique_ptr< Expander >	E
	)

addExpander - Add an expander for Records with the named super class.

Definition at line 275 of file SetTheory.cpp.

◆ addFieldExpander()

void SetTheory::addFieldExpander	(	StringRef	ClassName,
		StringRef	FieldName
	)

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 d> { dag Elts = d; }

Definition at line 279 of file SetTheory.cpp.

◆ addOperator()

void SetTheory::addOperator	(	StringRef	Name,
		std::unique_ptr< Operator >	Op
	)

addOperator - Add a DAG operator.

Definition at line 271 of file SetTheory.cpp.

References Name.

◆ evaluate() [1/2]

void SetTheory::evaluate	(	Init *	Expr,
		RecSet &	Elts,
		ArrayRef< SMLoc >	Loc
	)

evaluate - Evaluate Expr and append the resulting set to Elts.

Definition at line 283 of file SetTheory.cpp.

References llvm::tgtok::Def, llvm::dyn_cast(), expand(), llvm::Init::getAsString(), llvm::DagInit::getOperator(), I, llvm::SetVector< T, Vector, Set >::insert(), and llvm::PrintFatalError().

◆ evaluate() [2/2]

template<typename Iter >

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

inline

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

Definition at line 132 of file SetTheory.h.

References evaluate(), and expand().

◆ expand()

const RecVec * SetTheory::expand ( Record * Set )

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.
