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 --- test/CodeGen/ARM/2009-08-23-linkerprivate.ll | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'test/CodeGen/ARM/2009-08-23-linkerprivate.ll') diff --git a/test/CodeGen/ARM/2009-08-23-linkerprivate.ll b/test/CodeGen/ARM/2009-08-23-linkerprivate.ll index 0fad533b6c..392c70a9fd 100644 --- a/test/CodeGen/ARM/2009-08-23-linkerprivate.ll +++ b/test/CodeGen/ARM/2009-08-23-linkerprivate.ll @@ -2,7 +2,7 @@ ; ModuleID = '/Volumes/MacOS9/tests/WebKit/JavaScriptCore/profiler/ProfilerServer.mm' -@"\01l_objc_msgSend_fixup_alloc" = linker_private hidden global i32 0, section "__DATA, __objc_msgrefs, coalesced", align 16 ; [#uses=0] +@"\01l_objc_msgSend_fixup_alloc" = linker_private_weak hidden global i32 0, section "__DATA, __objc_msgrefs, coalesced", align 16 ; CHECK: .globl l_objc_msgSend_fixup_alloc ; CHECK: .weak_definition l_objc_msgSend_fixup_alloc -- cgit v1.2.3
