Linker: correctly link in dbg.declare Given source IR: call void @llvm.dbg.declare(metadata !{i32* %argc.addr}, metadata !14), !dbg !15 we used to generate call void @llvm.dbg.declare(metadata !27, metadata !28), !dbg !29 !27 = metadata !{null} With this patch, we will correctly generate call void @llvm.dbg.declare(metadata !{i32* %argc.addr}, metadata !27), !dbg !28 Looking up %argc.addr in ValueMap will return null, since %argc.addr is already correctly set up, we can use identity mapping. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173946 91177308-0d34-0410-b5e6-96231b3b80d8 Manman Ren 7 years ago
