// This file implements a pass to forward affine memref stores to loads, thereby
|
|
// potentially getting rid of intermediate memrefs entirely. It also removes
|
|
// redundant loads.
|
|
// TODO: In the future, similar techniques could be used to eliminate
|
|
// dead memref store's and perform more complex forwarding when support for
|
|
// SSA scalars live out of 'affine.for'/'affine.if' statements is available.
