I started this patch as a refactoring, tried to make a helper for getting symbol names, similar to how we get section names used in warning messages. So this patch cleanups the code and fixes an issue: symbol names in warning messages were not demangled. Differential revision: https://reviews.llvm.org/D68012 llvm-svn: 372867
