The following classes enable support for parsing and printing resources within MLIR assembly formats.
Resources are a mechanism by which dialects, and external clients, may attach additional information when parsing or printing IR without that information being encoded in the IR itself. Resources are not uniqued within the MLIR context, are not attached directly to any operation, and are solely intended to live and be processed outside of the immediate IR.
Resources are encoded using a key-value pair nested within dictionaries anchored either on a dialect, or an externally registered entity. Dictionaries anchored on dialects use the dialect namespace directly, and dictionaries anchored on external entities use a provided unique identifier. The resource key is an identifier used to disambiguate the data. The resource value may be stored in various limited forms, but general encodings use a string (human readable) or blob format (binary). Within the textual format, an example may be of the form:
{-# // The dialect_resources section within the file-level metadata // dictionary is used to contain any dialect resource entries. dialect_resources: { // Here is a dictionary anchored on "foo_dialect", which is a dialect // namespace. foo_dialect: { // some_dialect_resource is a key to be interpreted by the dialect, // and used to initialize/configure/etc. some_dialect_resource: "Some important resource value" } }, // The external_resources section within the file-level metadata // dictionary is used to contain any non-dialect resource entries. external_resources: { // Here is a dictionary anchored on "mlir_reproducer", which is an // external entity representing MLIR's crash reproducer functionality. mlir_reproducer: { // pipeline is an entry that holds a crash reproducer pipeline // resource. pipeline: "func.func(canonicalize,cse)" } } #-} This class represents a processed binary blob of data. A resource blob is essentially a collection of data, potentially mutable, with an associated deleter function (used if the data needs to be destroyed).
