From 5e721d768254a920b78b9129d79a84c0163cb3f4 Mon Sep 17 00:00:00 2001 From: Bill Wendling Date: Thu, 1 Jul 2010 21:55:59 +0000 Subject: Implement the "linker_private_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. However, this linkage isn't specific to Objective-C. 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". Currently only supported on Darwin platforms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107433 91177308-0d34-0410-b5e6-96231b3b80d8 --- tools/llvm-nm/llvm-nm.cpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'tools/llvm-nm') diff --git a/tools/llvm-nm/llvm-nm.cpp b/tools/llvm-nm/llvm-nm.cpp index 2baf532..fd7e7f6 100644 --- a/tools/llvm-nm/llvm-nm.cpp +++ b/tools/llvm-nm/llvm-nm.cpp @@ -89,7 +89,8 @@ static char TypeCharForSymbol(GlobalValue &GV) { static void DumpSymbolNameForGlobalValue(GlobalValue &GV) { // Private linkage and available_externally linkage don't exist in symtab. if (GV.hasPrivateLinkage() || GV.hasLinkerPrivateLinkage() || - GV.hasAvailableExternallyLinkage()) return; + GV.hasLinkerPrivateWeakLinkage() || GV.hasAvailableExternallyLinkage()) + return; const std::string SymbolAddrStr = " "; // Not used yet... char TypeChar = TypeCharForSymbol(GV); -- cgit v1.1
