Tasks

• Create an incremental tri-color mark GC module

• Integrate the new incremental GC into the existing system (See #670)

• Rename files in src/gc for sanity, suggested names:
  • memory.c -> alloc_memory.c or mem_allocate.c (r39002)
  • register.c -> alloc_registers.c or reg_allocate.c (r39003)
  • resources.c -> alloc_resources.c or resource_allocate.c (r39004)

• Collapse src/gc/smallobject.c into src/gc/api.c.(r39022 and r39023)

• Consider deleting src/gc/res_lea.c (doesn't work anyway) (See #655 and #490)

• Move src/malloc.c and src/malloc-trace.c into src/gc (not strictly GC, but want to group all memory management), consider deleting if only used by src/gc/res_lea.c (r39006)

Completed Tasks

---

Improve abstraction/encapsulation for existing GC modules. (r38654 and later)

If there are any non-API functions in src/gc/api.c move them into another file, possibly src/gc/common.c to indicate that they're internal to the GC system only, but shared between all the GC modules. (r38654 file currently named "mark_sweep.c")

---

Renamed all API functions to Parrot_gc_* (r34775).

---

Renamed files:

• dod.c -> api.c and dod.h -> gc_api.h (r34774)
• gc_gms.c -> generational_ms.c (r34795)
• gc_ims.c -> incremental_ms.c (r34796)
