Refactor Metadata #342

javadamiri · 2021-06-08T07:58:39Z

This PR refactors metadata so that it becomes more general and some of its use-cases such as gc_byte and header_byte become consistent with other uses of metadata, and closes issue #320.

A summary of changes:

1 - Make side_metadata a sub-module of the metadata module and generalise the SideMetadataSpec to MetadataSpec with an additional field to indicate whether the spec is on-side or in-header.
2 - Add optional atomic ordering to metadata operations.
3 - Move the definition of per-object Metadata specifications to the VM object model.
4 - Remove gc_byte and header_byte modules.

The new metadata design differentiates per-object metadata (e.g. forwarding-bits and marking-bit) from other types of metadata including per-address (e.g. alloc-bit) and per-X (where X != object size), because the per-object metadata can optionally be kept in the object headers.

MMTk now acknowledges the VM-dependant nature of the in-object metadata, and asks the VM bindings to contribute by implementing the related parts in the ObjectModel.
