theraven	34f7baf8d7	Added a fast path for ARC. Now, if a class implements ARC-compatible retain / release / autorelease methods, we don't call them at all. Instead, we inline them in the ARC accessors. This avoids all of the overhead of the message send (lookup and call) and should make ARC quite a bit faster than manual reference counting.	2011-07-03 11:14:29 +00:00
theraven	fcc47bc7ce	Fix building without GC support. Still need to make sure that some of the GC functions always work, since they are expected to be no-ops in non-GC mode.	2011-05-25 12:25:27 +00:00
theraven	9dcc66f7f6	Make sure that associated objects and blocks use GC-scanned memory in GC mode. ... Blocks do not yet support __weak bound variables. This needs fixing before the release.	2011-05-23 16:24:45 +00:00
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.	2011-05-22 23:02:04 +00:00
