FileCheck-ify more grep tests with quoted double quotes This required some tedious reordering to match clang's order. Presumably these ObjC tests were generated based on llvm-gcc's output ordering. llvm-svn: 179282

[Objective-c] Stop attaching section "datacoal_nt" to global variables. The current macho linker just copies symbols in section datacoal_nt to section data, so it doesn't really matter whether or not section "datacoal_nt" is attached to the global variable. This is a follow-up to r250370, which made changes in llvm to stop putting functions and data in the *coal* sections. rdar://problem/24528611 llvm-svn: 260496

Various fixes to symbols used for Obj-C x86_64 metadata. - Changed method names to match gcc (categories names still aren't mangled in). - Expose correct name for class and metadata symbols (although -fvisibility=hidden isn't yet correct). - Remove several things from llvm.used that didn't need to be there (I suspect this can still be trimmed). - Don't use asm-prefix extension for _objc_empty_{cache,vtable} (not needed). - Hide EH type class info with -fvisibility=hidden - Change setGlobal[Option]Visibility to not change the visibility of functions with internal linkage. llvm-svn: 68510

IRgen/NeXT: Fix several alignment issues with Objective-C metadata symbols: - Fix some places that had the alignment hard coded. - Use ABI type alignment, not preferred type alignment -- neither of this is exactly right, as we really want the C type alignment as required by the runtime, but the ABI alignment is a more correct choice. This should be equivalent for x86_64, but fixes the alignment for ARM. llvm-svn: 102314
