theraven	ad16172625	First pass at implementing Apple-compatible GC using Boehm. Still needs some tidying, but the following work: - __strong pointers, preventing objects from being freed _ __weak pointers are automatically freed when the last remaining __strong pointer goes away - objc_gc_{retain,release}_np() functions, which can be used to implement CFRetain() and CFRelease() (adds an reference count - the object will not be collected until after its last retain is gone.	15 years ago

theraven	6c7cf4a5a6	Add visibility attributes on all internal functions so that we aren't ever exporting them outside of libobjc.	15 years ago
