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.
