David Chisnall	b3f7b1bac3	Remove Boehm GC support code. ... This removes all support for GC mode. This was deprecated by Apple in OS X 10.8 (2012) and never supported in iOS. Very little code ever tried to use it with this runtime. It's gone from the build system already.	3 years ago
theraven	6a27408e9e	Fix malloc() / free() imbalance.	15 years ago
theraven	3a27521f57	Add flag for identifying modules that use ARC.	15 years ago
theraven	d1199844cb	Lock the GC mode once something has queried it. All of the GNUstep code that ... does run-time detection of whether to use GC calls objc_collecting_enabled() (sometimes indirectly, via NSGarbageCollector) to see if we're in GC mode. After any of these calls, it is not safe to switch modes.	15 years ago
theraven	fe5d1b892a	Tweak GC check, make sure GC_init() is called even when ObjC code isn't using GC (stuff internal to the runtime may be)	15 years ago
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.	15 years ago
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.	15 years ago
theraven	929f8f95b4	Improved a few GC functions. ... Added objc-auto.h header, providing (documented) public interfaces to this functionality.	15 years ago
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
