‘memref_ext’ Dialect

extended memref dialect

Operations

memref_ext.alloc_workspace (::bishengir::memref_ext::AllocWorkspaceOp)

Workspace memory allocation operation.

Syntax:

operation ::= `memref_ext.alloc_workspace` `(`$dynamicSize`)` (`from` $workspaceArg^)? ( `offset` `=` `[`$offset^`]`)?
              attr-dict `:` (`from` type($workspaceArg)^ `to`)? type($memref)

The alloc_workspace operation allocates a region of workspace memory. Example:

memref_ext.alloc_workspace() : memref<100xi8>
memref_ext.alloc_workspace(%dynamic) : memref<2x?xi32>
memref_ext.alloc_workspace(%dynamic) from %arg offset = [%offset] : from memref<?xi8> to memref<2x?xi32>
