Classes
struct	llvm::DelinearizationPrinterPass

Namespaces
namespace	llvm
	This is an optimization pass for GlobalISel generic memory operations.

Functions
void	llvm::findArrayDimensions (ScalarEvolution &SE, SmallVectorImpl< const SCEV * > &Terms, SmallVectorImpl< const SCEV * > &Sizes, const SCEV *ElementSize)
	Compute the array dimensions Sizes from the set of Terms extracted from the memory access function of this SCEVAddRecExpr (second step of delinearization).
void	llvm::collectParametricTerms (ScalarEvolution &SE, const SCEV *Expr, SmallVectorImpl< const SCEV * > &Terms)
	Collect parametric terms occurring in step expressions (first step of delinearization).
void	llvm::computeAccessFunctions (ScalarEvolution &SE, const SCEV *Expr, SmallVectorImpl< const SCEV * > &Subscripts, SmallVectorImpl< const SCEV * > &Sizes)
	Return in Subscripts the access functions for each dimension in Sizes (third step of delinearization).
void	llvm::delinearize (ScalarEvolution &SE, const SCEV *Expr, SmallVectorImpl< const SCEV * > &Subscripts, SmallVectorImpl< const SCEV * > &Sizes, const SCEV *ElementSize)
	Split this SCEVAddRecExpr into two vectors of SCEVs representing the subscripts and sizes of an array access.
bool	llvm::getIndexExpressionsFromGEP (ScalarEvolution &SE, const GetElementPtrInst *GEP, SmallVectorImpl< const SCEV * > &Subscripts, SmallVectorImpl< int > &Sizes)
	Gathers the individual index expressions from a GEP instruction.
bool	llvm::tryDelinearizeFixedSizeImpl (ScalarEvolution *SE, Instruction *Inst, const SCEV *AccessFn, SmallVectorImpl< const SCEV * > &Subscripts, SmallVectorImpl< int > &Sizes)
	Implementation of fixed size array delinearization.
