Fariborz Jahanian	a644f9cb73	arc-objc++: Issue an arc specific diagnostic when overload resolution ... fails because of lifetime differences of parameter and argument type. // rdar://9790531 llvm-svn: 135593	2011-07-20 17:14:09 +00:00
John McCall	24fc0decfe	Change the driver's logic about Objective-C runtimes: abstract out a ... structure to hold inferred information, then propagate each invididual bit down to -cc1. Separate the bits of "supports weak" and "has a native ARC runtime"; make the latter a CodeGenOption. The tool chain is still driving this decision, because it's the place that has the required deployment target information on Darwin, but at least it's better-factored now. llvm-svn: 134453	2011-07-06 00:26:06 +00:00
John McCall	63f844494d	ARC writeback isn't supposed to apply to local indirect pointers, ... only to pointers to locals. But it should work inside blocks, too. llvm-svn: 133969	2011-06-27 23:59:58 +00:00
Argyrios Kyrtzidis	cff00d9c12	Rename objc_lifetime -> objc_ownership, and modify diagnostics to talk about 'ownership', not 'lifetime'. ... rdar://9477613. llvm-svn: 133779	2011-06-24 00:08:59 +00:00
John McCall	31168b077c	Automatic Reference Counting. ... Language-design credit goes to a lot of people, but I particularly want to single out Blaine Garst and Patrick Beard for their contributions. Compiler implementation credit goes to Argyrios, Doug, Fariborz, and myself, in no particular order. llvm-svn: 133103	2011-06-15 23:02:42 +00:00
