2016-05-03Move llvm-readobj/StreamWriter to Support.Zachary Turner1-3/+4
We wish to re-use this from llvm-pdbdump, and it provides a nice way to print structured data in scoped format that could prove useful for many other dumping tools as well. Moving to support and changing name to ScopedPrinter to better reflect its purpose. llvm-svn: 268342

2016-04-06Thread Expected<...> up from createMachOObjectFile() to allow llvm-objdump ↵Kevin Enderby1-3/+3
to produce a real error message Produce the first specific error message for a malformed Mach-O file describing the problem instead of the generic message for object_error::parse_failed of "Invalid data was encountered while parsing the file”.  Many more good error messages will follow after this first one. This is built on Lang Hames’ great work of adding the ’Error' class for structured error handling and threading Error through MachOObjectFile construction. And making createMachOObjectFile return Expected<...> . So to to get the error to the llvm-obdump tool, I changed the stack of these methods to also return Expected<...> : object::ObjectFile::createObjectFile() object::SymbolicFile::createSymbolicFile() object::createBinary() Then finally in ParseInputMachO() in MachODump.cpp the error can be reported and the specific error message can be printed in llvm-objdump and can be seen in the existing test case for the existing malformed binary but with the updated error message. Converting these interfaces to Expected<> from ErrorOr<> does involve touching a number of places. To contain the changes for now use of errorToErrorCode() and errorOrToExpected() are used where the callers are yet to be converted. 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(ObjOrErr.takeError()) so the buggy code will not crash since needed to deal with the Error. Note there is one fix also needed to lld/COFF/InputFiles.cpp 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. llvm-svn: 265606

2015-11-05Reapply r250906 with many suggested updates from Rafael Espindola.Kevin Enderby1-1/+4
The needed lld matching changes to be submitted immediately next, but this revision will cause lld failures with this alone which is expected. This removes the eating of the error in Archive::Child::getSize() when the characters in the size field in the archive header for the member is not a number. To do this we have all of the needed methods return ErrorOr to push them up until we get out of lib. Then the tools and can handle the error in whatever way is appropriate for that tool. So the solution is to plumb all the ErrorOr stuff through everything that touches archives. This include its iterators as one can create an Archive object but the first or any other Child object may fail to be created due to a bad size field in its header. Thanks to Lang Hames on the changes making child_iterator contain an ErrorOr<Child> instead of a Child and the needed changes to ErrorOr.h to add operator overloading for * and -> . We don’t want to use llvm_unreachable() as it calls abort() and is produces a “crash” and using report_fatal_error() to move the error checking will cause the program to stop, neither of which are really correct in library code. There are still some uses of these that should be cleaned up in this library code for other than the size field. The test cases use archives with text files so one can see the non-digit character, in this case a ‘%’, in the size field. These changes will require corresponding changes to the lld project. That will be committed immediately after this change. But this revision will cause lld failures with this alone which is expected. llvm-svn: 252192
