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