There were two issues here: 1. At the very least, scattered relocations cannot use the same code to determine the corresponding symbol being referred to. For some reason we pretend there is no symbol, even when one actually exists in the symtab, so to match this behaviour getRelocationSymbol should simply return symbols_end for scattered relocations. 2. Printing "-" when we can't get a symbol (including the scattered case, but not exclusively), isn't that helpful. In both cases there *is* interesting information in that field, so we should print it. As hex will do. Small part of rdar://problem/17553104 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@212332 91177308-0d34-0410-b5e6-96231b3b80d8
