Classes
struct	BitTestBlock
struct	BitTestCase
struct	CaseBits
struct	CaseBlock
	This structure is used to communicate between SelectionDAGBuilder and SDISel for the code generation of additional basic blocks needed by multi-case switch statements. More...
struct	CaseCluster
	A cluster of case labels. More...
struct	JumpTable
struct	JumpTableHeader
class	SwitchLowering
struct	SwitchWorkListItem

using	BitTestInfo = SmallVector<BitTestCase, 3>
using	SwitchWorkList = SmallVector<SwitchWorkListItem, 4>

Enumerations
enum	CaseClusterKind { CC_Range, CC_JumpTable, CC_BitTests }

Functions
void	sortAndRangeify (CaseClusterVector &Clusters)
	Sort Clusters and merge adjacent cases.
uint64_t	getJumpTableRange (const CaseClusterVector &Clusters, unsigned First, unsigned Last)
	Return the range of values within a range.
uint64_t	getJumpTableNumCases (const SmallVectorImpl< unsigned > &TotalCases, unsigned First, unsigned Last)
	Return the number of cases within a range.
