Hi @Lewuathe, are you asking whether the restrictions on `memref.reshape` need to be loosened in order to permit non-identity layout maps? That could be a potential solution, though I am not privy to the reasoning behind the layout map restriction.

At the moment, bufferization can create `memref.reshape` operations with non-identity layouts.
The proposed solution in this change is to allocate a new buffer for the `memref.reshape` when the bufferization process attempts to reuse a buffer with a non-identity layout.
