Detailed Description
Pattern to canonicalize trivial vector.transfer_read operations on subviews.
This pattern eliminates unnecessary memref.subview operations when the transfer_read accesses the subview with all-zero indices. It transforms:
INPUT: subview = memref.subview memref [offset0, offset1, ...] result = vector.transfer_read subview[0, 0, ...]
OUTPUT: result = vector.transfer_read memref[offset0, offset1, ...]
The pattern only matches when:
- The base of transfer_read is defined by a memref.subview operation
- All indices in the transfer_read are constant zeros
