Bill Wendling	e1c4a1babd	Update to use references to attribute groups instead of listing the attributes on the call/invoke instructions. ... llvm-svn: 175878	2013-02-22 09:10:20 +00:00
John McCall	12cc42aa1b	Destroy arrays and ARC fields when throwing out of ctors. ... Previously we were only handling non-array fields of class type. Testcases derived from a patch by WenHan Gu. llvm-svn: 174146	2013-02-01 05:11:40 +00:00
John McCall	e68b8f4dcc	At -O0, prefer objc_storeStrong with a null new value to the ... combination of a load+objc_release; this is generally better for tools that try to track why values are retained and released. Also use objc_storeStrong when copying a block (again, only at -O0), which requires us to do a preliminary store of null in order to compensate for objc_storeStrong's assign semantics. llvm-svn: 166085	2012-10-17 02:28:37 +00:00
John McCall	9701731a3e	When initializing a catch variable in ARC, be sure to emit retains ... or whatever else is required for the initialization instead of assuming it can be done with a simple store. Fixes PR11732. llvm-svn: 148325	2012-01-17 20:16:56 +00:00
