Modules

• address
  An abstract of memory address and object reference.
• alloc
  Allocators Various allocators implementation.
• api_util
  Helpers for making native APIs. This module contain helpers for the convenience of exposing the MMTk API to native (usually C/C++) programs.
• constants
  Constants used in MMTk
• conversions
  Calculation, conversion and rounding for memory related numbers.
• copy
  The copy allocators for a GC worker.
• heap
  Heap implementation, including page resource, mmapper, etc.
• linear_scan
  Linear scan through a heap range
• malloc
  Various malloc implementations (conditionally compiled by features) This module exposes a set of malloc API. They are currently implemented with the library malloc. This may change in the future, and will be replaced with a native MMTk implementation. We have two versions for each function:
• memory
  Wrapper functions for memory syscalls such as mmap, mprotect, etc.
• metadata
  Metadata (OnSide or InHeader) implementation. This is a generic module to work with metadata including side metadata and in-object metadata.
• opaque_pointer
  Opaque pointers used in MMTk, e.g. VMThread.
• options
  MMTk command line options.
