Saleem Abdulrasool	3f307518f8	CodeGen: mark ObjC cstring literals as unnamed_addr ... These are all emitted into a section with a cstring_literal attribute. The attribute permits the linker to coalesce the string contents. The address of the strings are not important. llvm-svn: 281855	2016-09-18 16:12:14 +00:00
Saleem Abdulrasool	0c54dc862e	CodeGen: mark ObjC cstring literals as constant ... These strings are constants, mark them as such. This doesn't matter too much in practice on MachO since the constants are placed into a special section and not referred to directly. llvm-svn: 281854	2016-09-18 16:12:04 +00:00
John McCall	17f0275d4c	Initialize @catch variables correctly in fragile-runtime ARC. ... llvm-svn: 251677	2015-10-30 00:56:02 +00:00
John McCall	09ec1ecf03	Enable ARC on the fragile runtime. ... This is almost entirely a matter of just flipping a switch. 99% of the runtime support is available all the way back to when it was implemented in the non-fragile runtime, i.e. in Lion. However, fragile runtimes do not recognize ARC-style ivar layout strings, which means that accessing __strong or __weak ivars reflectively (e.g. via object_setIvar) will end up accessing the ivar as if it were __unsafe_unretained. Therefore, when using reflective technologies like KVC, be sure that your paths always refer to a property. rdar://23209307 llvm-svn: 250955	2015-10-21 22:06:03 +00:00
