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

Don't manually insert L prefixes. Simply marking the symbol private conveys the desire to hide them to LLVM. llvm-svn: 221451

[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

[CodeGen][ObjC] Remove the leading `l_` from ObjC symbols and make private symbols in the __DATA segment internal. This prevents the linker from removing the symbol names. Keeping the symbols visible enables tools to collect various information about the symbols, for example, tools that discover whether or not a symbol gets dirtied. rdar://problem/48887111 Differential Revision: https://reviews.llvm.org/D61454 llvm-svn: 360359

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
