Add MCObjectFileInfo and sink the MCSections initialization code from TargetLoweringObjectFileImpl down to MCObjectFileInfo. TargetAsmInfo is done to one last method. It's almost gone! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135569 91177308-0d34-0410-b5e6-96231b3b80d8 2011-07-20 05:58:47 +00:00			`; RUN: llc < %s -march=ppc32 -mtriple=powerpc-apple-darwin \| FileCheck %s`
Make linkerprivate work for ARM and PPC. Testcase covers all Darwin targets; could be split into separate tests for the chip subdirectories, but from Chris' last mail on testing I assume he'd rather have only one test. Generic seems to be the best available, maybe there should be a Darwin subdirectory? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79877 91177308-0d34-0410-b5e6-96231b3b80d8 2009-08-24 01:03:42 +00:00

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 2010-07-01 21:55:59 +00:00			`@"\01l_objc_msgSend_fixup_alloc" = linker_private_weak hidden global i32 0, section "__DATA, __objc_msgrefs, coalesced", align 16`
