LLVM: Prefetch Struct Reference (original) (raw)

A record for a potential prefetch made during the initial scan of the loop. More...

Public Member Functions
	Prefetch (const SCEVAddRecExpr L, Instruction I)
	Constructor to create a new Prefetch for I.

void	addInstruction (Instruction I, DominatorTree DT=nullptr, int64_t PtrDiff=0)
	Add the instruction.

Public Attributes
const SCEVAddRecExpr *	LSCEVAddRec
	The address formula for this prefetch as returned by ScalarEvolution.

Instruction *	InsertPt = nullptr
	The point of insertion for the prefetch instruction.

bool	Writes = false
	True if targeting a write memory access.

Instruction *	MemI = nullptr
	The (first seen) prefetched instruction.

A record for a potential prefetch made during the initial scan of the loop.

This is used to let a single prefetch target multiple memory accesses.
