Kevin Enderby 813e0cf966 Thread Expected<...> up from libObject’s getName() for symbols to allow llvm-objdump to produce a good error message. ... Produce another specific error message for a malformed Mach-O file when a symbol’s string index is past the end of the string table. The existing test case in test/Object/macho-invalid.test for macho-invalid-symbol-name-past-eof now reports the error with the message indicating that a symbol at a specific index has a bad sting index and that bad string index value. Again converting interfaces to Expected<> from ErrorOr<> does involve touching a number of places. Where the existing code reported the error with a string message or an error code it was converted to do the same. There is some code for this that could be factored into a routine but I would like to leave that for the code owners post-commit to do as they want for handling an llvm::Error. An example of how this could be done is shown in the diff in lib/ExecutionEngine/RuntimeDyld/RuntimeDyldImpl.h which had a Check() routine already for std::error_code so I added one like it for llvm::Error . Also there some were bugs in the existing code that did not deal with the old ErrorOr<> return values.  So now with Expected<> since they must be checked and the error handled, I added a TODO and a comment: “// TODO: Actually report errors helpfully” and a call something like consumeError(NameOrErr.takeError()) so the buggy code will not crash since needed to deal with the Error. Note there fixes needed to lld that goes along with this that I will commit right after this. So expect lld not to built after this commit and before the next one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@266919 91177308-0d34-0410-b5e6-96231b3b80d8		2016-04-20 21:24:34 +00:00
