* [CodeView] Hook up CodeViewRecordIO to type serialization path.Zachary Turner2016-11-081-5/+5
| | | | | | | | | | | | Previously support had been added for using CodeViewRecordIO to read (deserialize) CodeView type records. This patch adds support for writing those same records. With this patch, reading and writing of CodeView type records finally uses a single codepath. Differential Revision: https://reviews.llvm.org/D26253 llvm-svn: 286304

* llvm-readobj: add support for printing GNU NotesSaleem Abdulrasool2016-08-301-0/+6
| | | | | | | | | Add support for printing the GNU Notes. This allows an easy way to view the build id for a binary built with the build id. Currently, this only handles the GNU notes, though it would be easy to extend for other note types (default, FreeBSD, NetBSD, etc). Only the GNU style is supported currently. llvm-svn: 280131

* [CodeView] Decouple record deserialization from visitor dispatch.Zachary Turner2016-08-051-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now, our use case for the visitor has been to take a stream of bytes representing a type stream, deserialize the records in sequence, and do something with them, where "something" is determined by how the user implements a particular set of callbacks on an abstract class. For actually writing PDBs, however, we want to do the reverse. We have some kind of description of the list of records in their in-memory format, and we want to process each one. Perhaps by serializing them to a byte stream, or perhaps by converting them from one description format (Yaml) to another (in-memory representation). This was difficult in the current model because deserialization and invoking the callbacks were tightly coupled. With this patch we change this so that TypeDeserializer is itself an implementation of the particular set of callbacks. This decouples deserialization from the iteration over a list of records and invocation of the callbacks. TypeDeserializer is initialized with another implementation of the callback interface, so that upon deserialization it can pass the deserialized record through to the next set of callbacks. In a sense this is like an implementation of the Decorator design pattern, where the Deserializer is a decorator. This will be useful for writing Pdbs from yaml, where we have a description of the type records in Yaml format. In this case, the visitor implementation would have each visitation callback method implemented in such a way as to extract the proper set of fields from the Yaml, and it could maintain state that builds up a list of these records. Finally at the end we can pass this information through to another set of callbacks which serializes them into a byte stream.

* [Object] Change Archive::child_iterator for better interop with Error/Expected.Lang Hames2016-07-131-4/+15
| | | | | | | | | | | | | | | | | | | | | | | See http://reviews.llvm.org/D22079 Changes the Archive::child_begin and Archive::children to require a reference to an Error. If iterator increment fails (because the archive header is damaged) the iterator will be set to 'end()', and the error stored in the given Error&. The Error value should be checked by the user immediately after the loop. E.g.: Error Err; for (auto &C : A->children(Err)) { // Do something with archive child C. } // Check the error immediately after the loop. if (Err) return Err; Failure to check the Error will result in an abort() when the Error goes out of scope (as guaranteed by the Error class). llvm-svn: 275316
* Finish cleaning up most of the error handling in libObject’s ↵Kevin Enderby2016-06-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MachOUniversalBinary and its clients to use the new llvm::Error model for error handling. Changed getAsArchive() from ErrorOr<...> to Expected<...> so now all interfaces there use the new llvm::Error model for return values. In the two places it had if (!Parent) this is actually a program error so changed from returning errorCodeToError(object_error::parse_failed) to calling report_fatal_error() with a message. In getObjectForArch() added error messages to its two llvm::Error return values instead of returning errorCodeToError(object_error::arch_not_found) with no error message. For the llvm-obdump, llvm-nm and llvm-size clients since the only binary files in Mach-O Universal Binaries that are supported are Mach-O files or archives with Mach-O objects, updated their logic to generate an error when a slice contains something like an ELF binary instead of ignoring it. And added a test case for that. The last error stuff to be cleaned up for libObject’s MachOUniversalBinary is the use of errorOrToExpected(Archive::create(ObjBuffer)) which needs Archive::create() to be changed from ErrorOr<...> to Expected<...> first, which I’ll work on next. llvm-svn: 274079

| | | | | | | | | | | | | | | | | | | when the object is from a slice of a Mach-O Universal Binary use something like "foo.o (for architecture i386)" as part of the error message when expected. Also fixed places in these tools that were ignoring object file errors from MachOUniversalBinary::getAsObjectFile() when the code moved on to see if the slice was an archive. To do this MachOUniversalBinary::getAsObjectFile() and MachOUniversalBinary::getObjectForArch() were changed from returning ErrorOr<...> to Expected<...> then that was threaded up to its users. Converting these interfaces to Expected<> from ErrorOr<> does involve touching a number of places. To contain the changes for now the use of errorToErrorCode() is still used in two places yet to be fully converted. llvm-svn: 271332

* [codeview] Add type stream merging prototypeReid Kleckner2016-05-141-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This code is intended to be used as part of LLD's PDB writing. Until that exists, this is exposed via llvm-readobj for testing purposes. Type stream merging uses the following algorithm: - Begin with a new empty stream, and a new empty hash table that maps from type record contents to new type index. - For each new type stream, maintain a map from source type index to destination type index. - For each record, copy it and rewrite its type indices to be valid in the destination type stream. - If the new type record is not already present in the destination stream hash table, append it to the destination type stream, assign it the next type index, and update the two hash tables. - If the type record already exists in the destination stream, discard it and update the type index map to forward the source type index to the existing destination type index.

* Thread Expected<...> up from createMachOObjectFile() to allow llvm-objdump ↵Kevin Enderby2016-04-061-3/+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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
