> Could this call `reportError(Twine)` at least? Ideally, I'd prefer it if it called a function that included the file name too. I think there's one in llvm-readobj.cpp that would be useful: `reportError(StringRef Input, Error Err)`. I don't see a reason that this couldn't be exposed to the rest of llvm-readobj.
I changed to `reportError(Twine)`. It looks a bit problematic to get a file name here and I am not sure it is very useful to do this change right now, because actually, I think we do not need this error at all here. I introduced it to minimize the change of the existent logic (i.e. we already had this fatal error at deeper levels), but I think `getSectionName` actually should never fail and terminate the proccess. It probably might return a `Error` instead or a pair of section name + warning message, or something else, but idea is that if we can`t get the section name because of any reason we should probably continue dumping and just show something like `<section name unknown>` instead of the section name.
