Raw Normal View History

The Dwarf writer was comparing mangled and unmangled names for C++ code when we have an unreachable block in a function. This was triggering the assert. This is a horrid hack to cover this up. Oh! for a good debug info architecture! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57714 91177308-0d34-0410-b5e6-96231b3b80d8
