## vmkit-core flavors
|
|
|
|
We support three flavors of vmkit-core:
|
|
- `uncooperative`: This is the most conservative flavor. It exposes a BDWGC-like API, only provides Immix and MarkSweep GC plans,
|
|
and management of threads is fully internal to the library.
|
|
- `cooperative`: This is mostly-precise flavor. This flavor exposes advanced allocation API, requries runtime to call into `yieldpoint()`,
|
|
and also requires runtime to do write barriers and have precise object layout. Stack is left to be conservatively scanned.
|
|
- `full-precise`: This is precise flavor. Provides everything that `cooperative` provides, and also requires
|
|
runtime to not have any conservative assumptions such as conservative stack scanning.
