Module mmtk::plan::generational

Generational plans (with a copying nursery) Generational plans

Modules

• barrier
  Generational read/write barrier implementations.
• copying
  Generational copying (GenCopy) Plan: generational copying
• gc_work 🔒
• global 🔒
• immix
  Generational immix (GenImmix) Plan: generational immix

Structs

• ALLOCATOR_MAPPING 🔒

Constants

• ACTIVE_BARRIER
  Barrier overhead measurement:
• FULL_NURSERY_GC
  Full heap collection as nursery GC.
• GEN_CONSTRAINTS
  Constraints for generational plans. Each generational plan should overwrite based on this constant.
• RESERVED_ALLOCATORS 🔒

Functions

• create_gen_space_mapping 🔒
• new_generational_global_metadata_specs
  Create global side metadata specs for generational plans. This will call SideMetadataContext::new_global_specs(). So if a plan calls this, it should not call SideMetadataContext::new_global_specs() again.
