From 207855cff9b4811004b9720f28a5bd0adf3784b7 Mon Sep 17 00:00:00 2001 From: Bill Wendling Date: Tue, 29 Jun 2010 21:24:00 +0000 Subject: Introducing the "linker_weak" linkage type. This will be used for Objective-C 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 --- lib/Bitcode/Reader/BitcodeReader.cpp | 1 + 1 file changed, 1 insertion(+) (limited to 'lib/Bitcode/Reader/BitcodeReader.cpp') diff --git a/lib/Bitcode/Reader/BitcodeReader.cpp b/lib/Bitcode/Reader/BitcodeReader.cpp index a252da26f1..71efeff4d3 100644 --- a/lib/Bitcode/Reader/BitcodeReader.cpp +++ b/lib/Bitcode/Reader/BitcodeReader.cpp @@ -75,6 +75,7 @@ static GlobalValue::LinkageTypes GetDecodedLinkage(unsigned Val) { case 11: return GlobalValue::LinkOnceODRLinkage; case 12: return GlobalValue::AvailableExternallyLinkage; case 13: return GlobalValue::LinkerPrivateLinkage; + case 14: return GlobalValue::LinkerWeakLinkage; } } -- cgit v1.2.3-18-g5258
