The original code does not work correctly on executable files because the code is written in such a way that only object files are assumed to be given to llvm-objdump. Contents of RuntimeFunction are different between executables and objects. In executables, fields in RuntimeFunction have actual addresses to unwind info structures. On the other hand, in object files, the fields have zero value, but instead there are relocations pointing to the fields, so that Linker will fill them at link-time. So, when we are reading an object file, we need to use relocation info to find the location of unwind info. When executable, we should just look at the values in RuntimeFunction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202785 91177308-0d34-0410-b5e6-96231b3b80d8
