Uday Bondhugula fff1efbaf5 Updates to transformation/analysis passes/utilities. Update DMA generation pass ... and getMemRefRegion() to work with specified loop depths; add support for outgoing DMAs, store op's. - add support for getMemRefRegion symbolic in outer loops - hence support for DMAs symbolic in outer surrounding loops. - add DMA generation support for outgoing DMAs (store op's to lower memory space); extend getMemoryRegion to store op's. -memref-bound-check now works with store op's as well. - fix dma-generate (references to the old memref in the dma_start op were also being replaced with the new buffer); we need replace all memref uses to work only on a subset of the uses - add a new optional argument for replaceAllMemRefUsesWith. update replaceAllMemRefUsesWith to take an optional 'operation' argument to serve as a filter - if provided, only those uses that are dominated by the filter are replaced. - Add missing print for attributes for dma_start, dma_wait op's. - update the FlatAffineConstraints API PiperOrigin-RevId: 221889223		2019-03-29 14:00:51 -07:00
