[Pass][Bugfix] Disable re-use of non-flat buffers in StorageRewrite. - #10787
Merged
Conversation
As a follow-up from apache#9727, restricting StorageRewrite to only modify flat memory buffers. When rewriting, the existing algorithm in StorageRewrite flattens N-d allocations into 1-d allocations, preventing them from being exposed to the codegen.
Previously, these were ignored entirely. This worked so long as all allocations were 1-d, as `StorageRewrite` erroneously flattened merged arrays into 1-d.
