Public Member Functions
	SccInfo (const Function &F)
int	getSCCNum (const BasicBlock *BB) const
	If BB belongs to some SCC then ID of that SCC is returned, otherwise -1 is returned.
bool	isSCCHeader (const BasicBlock *BB, int SccNum) const
	Returns true if BB is a 'header' block in SCC with SccNum ID, false otherwise.
bool	isSCCExitingBlock (const BasicBlock *BB, int SccNum) const
	Returns true if BB is an 'exiting' block in SCC with SccNum ID, false otherwise.
void	getSccEnterBlocks (int SccNum, SmallVectorImpl< BasicBlock * > &Enters) const
	Fills in Enters vector with all such blocks that don't belong to SCC with SccNum ID but there is an edge to a block belonging to the SCC.
void	getSccExitBlocks (int SccNum, SmallVectorImpl< BasicBlock * > &Exits) const
	Fills in Exits vector with all such blocks that don't belong to SCC with SccNum ID but there is an edge from a block belonging to the SCC.

Member Function Documentation

getSccEnterBlocks()

void BranchProbabilityInfo::SccInfo::getSccEnterBlocks	(	int	SccNum,
		SmallVectorImpl< BasicBlock * > &	Enters
	)		const

Fills in Enters vector with all such blocks that don't belong to SCC with SccNum ID but there is an edge to a block belonging to the SCC.

References llvm::predecessors(), and llvm::SmallVectorTemplateBase< T, bool >::push_back().

getSccExitBlocks()

void BranchProbabilityInfo::SccInfo::getSccExitBlocks	(	int	SccNum,
		SmallVectorImpl< BasicBlock * > &	Exits
	)		const

Fills in Exits vector with all such blocks that don't belong to SCC with SccNum ID but there is an edge from a block belonging to the SCC.

getSCCNum()

int BranchProbabilityInfo::SccInfo::getSCCNum

(

const BasicBlock *

BB

)

const

If BB belongs to some SCC then ID of that SCC is returned, otherwise -1 is returned.

If BB belongs to more than one SCC at the same time result is undefined.

isSCCExitingBlock()

bool llvm::BranchProbabilityInfo::SccInfo::isSCCExitingBlock ( const BasicBlock *  BB, int  SccNum  ) const

inline

Returns true if BB is an 'exiting' block in SCC with SccNum ID, false otherwise.

Definition at line 254 of file BranchProbabilityInfo.h.

isSCCHeader()

bool llvm::BranchProbabilityInfo::SccInfo::isSCCHeader ( const BasicBlock *  BB, int  SccNum  ) const

inline

Returns true if BB is a 'header' block in SCC with SccNum ID, false otherwise.
