* Recommit r368812 "[llvm/Object] - Convert SectionRef::getName() to return ↵George Rimar2019-08-141-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Expected<>" Changes: no changes. A fix for the clang code will be landed right on top. Original commit message: SectionRef::getName() returns std::error_code now. Returning Expected<> instead has multiple benefits. For example, it forces user to check the error returned. Also Expected<> may keep a valuable string error message, what is more useful than having a error code. (Object\invalid.test was updated to show the new messages printed.) This patch makes a change for all users to switch to Expected<> version. Note: in a few places the error returned was ignored before my changes. In such places I left them ignored. My intention was to convert the interface used, and not to improve and/or the existent users in this patch. (Though I think this is good idea for a follow-ups to revisit such places and either remove consumeError calls or comment each of them to clarify why it is OK to have them).

* Switch LLVM to use 64-bit offsets (2/5)Igor Kudrin2019-08-061-1/+1
| | | | | | | | | This updates all libraries and tools in LLVM Core to use 64-bit offsets which directly or indirectly come to DataExtractor. Differential Revision: https://reviews.llvm.org/D65638 llvm-svn: 368014
* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

* [Decompression] Fail gracefully when out of memoryJonas Devlieghere2017-09-051-3/+11

* Move Object format code to lib/BinaryFormat.Zachary Turner2017-06-071-1/+1
| | | | | | | | | | | | This creates a new library called BinaryFormat that has all of the headers from llvm/Support containing structure and layout definitions for various types of binary formats like dwarf, coff, elf, etc as well as the code for identifying a file from its magic.

* Sort the remaining #include lines in include/... and lib/....Chandler Carruth2017-06-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | I did this a long time ago with a janky python script, but now clang-format has built-in support for this. I fed clang-format every line with a #include and let it re-sort things according to the precise LLVM rules for include ordering baked into clang-format these days. I've reverted a number of files where the results of sorting includes isn't healthy. Either places where we have legacy code relying on particular include ordering (where possible, I'll fix these separately) or where we have particular formatting around #include lines that I didn't want to disturb in this patch. This patch is *entirely* mechanical. If you get merge conflicts or anything, just ignore the changes in this patch and run clang-format over your #include lines in the files. Sorry for any noise here, but it is important to keep these things stable. I was seeing an increasing number of patches with irrelevant re-ordering of #include lines because clang-format was used. This patch at least isolates that churn, makes it easy to skip when resolving conflicts, and gets us to a clean baseline (again). llvm-svn: 304787
* [lib/Object] - Minor API update for llvm::Decompressor.George Rimar2017-05-181-5/+0
| | | | | | | | | | | | | | | | | I revisited Decompressor API (issue with it was triggered during D32865 review) and found it is probably provides more then we really need. Issue was about next method's signature: Error decompress(SmallString<32> &Out); It is too strict. At first I wanted to change it to decompress(SmallVectorImpl<char> &Out), but then found it is still not flexible because sticks to SmallVector. During reviews was suggested to use templating to simplify code. Patch do that. Differential revision: https://reviews.llvm.org/D33200 llvm-svn: 303331

Original commit message: [Support/Compression] - Change zlib API to return Error instead of custom status. Previously API returned custom enum values. Patch changes it to return Error with string description. That should help users to report errors in universal way. Differential revision: https://reviews.llvm.org/D28684 llvm-svn: 292226

* [lib/Object] - Introduce Decompressor class.George Rimar2017-01-111-0/+102
Decompressor intention is to reduce duplication of code. Currently LLD has own implementation of decompressor for compressed debug sections. This class helps to avoid it and share the code. LLD patch for reusing it is D28106 Differential revision: https://reviews.llvm.org/D28105 llvm-svn: 291675
