| //===- MemorySpace.h - Methods for codifying memory space values ----------===// |
| // |
| // Method that codify the convention for memory space values. MLIR itself does |
| // not have definition for the memory space values on (memref) types. It is left |
| // to the clients to do so. Here this is codified for IREE codegen. It is made |
| // consistent with what the lowering from Standard to SPIR-V in MLIR expects. |
