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.
