Thanks to dblaikie for updating the testcase! Debug info: (bugfix) C++ C/Dtors can be compiled to multiple functions, therefore, their declaration cannot have one DW_AT_linkage_name. The specific instances however can and should have that attribute. This patch reorders the code in DwarfUnit::getOrCreateSubprogramDIE() to emit linkage names for C/Dtors. rdar://problem/16362674. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206210 91177308-0d34-0410-b5e6-96231b3b80d8
