* Revert some unneeded parts of the change in r107886 for theKevin Enderby2010-07-082-2/+0
| | | | | | | | | | .weak_def_can_be_hidden directive. Chris pointed out that the MCAsmInfo.h/.cpp chunks aren't needed for this until the compiler starts generating these. And when that happens it will be more convenient for it to be a bool than a const char*. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107906 91177308-0d34-0410-b5e6-96231b3b80d8

* Introducing the "linker_weak" linkage type. This will be used for Objective-CBill Wendling2010-06-292-0/+2
| | | | | | | | | | | | | | | | | | | | metadata types which should be marked as "weak", but which the linker will remove upon final linkage. For example, the "objc_msgSend_fixup_alloc" symbol is defined like this: .globl l_objc_msgSend_fixup_alloc .weak_definition l_objc_msgSend_fixup_alloc .section __DATA, __objc_msgrefs, coalesced .align 3 l_objc_msgSend_fixup_alloc: .quad _objc_msgSend_fixup .quad L_OBJC_METH_VAR_NAME_1 This is different from the "linker_private" linkage type, because it can't have the metadata defined with ".weak_definition". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107205 91177308-0d34-0410-b5e6-96231b3b80d8
