* Make -Wincomplete-umbrella go through the VFSBen Langmuir2014-06-25
| | | | | | | By using vfs::recursive_directory_iterator, this warning will now fire when some or all of a module's headers are from VFS mappings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211746 91177308-0d34-0410-b5e6-96231b3b80d8
* Add vfs::recursive_directory_iteratorBen Langmuir2014-06-25
| | | | | | | | | For now, this is only used by its unit tests. It is similar to the API in llvm::sys::fs::recursive_directory_iterator, but without some of the more complex features like requesting that the iterator not recurse into the next directory, for example. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211732 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix test issues from r211623 and remove test-only APIBen Langmuir2014-06-24
| | | | | | | | | | | 1) missing iterator bits needed by libstdc++4.7 Using find_if was convenient, but since operator++ wasn't a good interface anyway, I just replaced with a range-based for loop and removed operator++ from the directory_iterator class. 2) stop relying on order of iterating real files git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211633 91177308-0d34-0410-b5e6-96231b3b80d8
* Add directory_iterator for (non-recursive) iteration of VFS directoriesBen Langmuir2014-06-24
| | | | | | | | The API is based on sys::fs::directory_iterator, but it allows iterating over overlays and the yaml-based VFS. For now, it isn't used by anything (except its tests). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211623 91177308-0d34-0410-b5e6-96231b3b80d8
* Replace llvm::error_code with std::error_code.Rafael Espindola2014-06-12

* Stopgap fix for finding module for a file mapped in the VFSBen Langmuir2014-05-23
| | | | | | | | | | | | | | | | If we lookup a path using its 'real' path first, we need to ensure that when we run header search we still use the VFS-mapped path or we will not be able to find the corresponding module for the header. The real problem is that we tie the name of a file to its underlying FileEntry, which is uniqued by inode, so we only ever get the first name it is looked up by. This doesn't work with modules, which rely on a specific file system structure. I'm hoping to have time to write up a proposal for fixing this more permanently soon, but as a stopgap this patch updates the name of the file's directory if it comes from a VFS mapping. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@209534 91177308-0d34-0410-b5e6-96231b3b80d8
* VirtualFileSystem: Fix a few directory traversal bugs in VFSWriterJustin Bogner2014-05-21
| | | | | | | | | | | There are a couple of issues with writing VFS maps that are awkward to fix within the current mutually recursive approach. Instead, replace the algorithm with an iterative version that uses an explicit stack of directories. Includes tests for cases the old approach was tripping on. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@209332 91177308-0d34-0410-b5e6-96231b3b80d8
* VirtualFileSystem: Add YAMLVFSWriter to generate VFS mapping filesJustin Bogner2014-05-20
| | | | | | | | | This moves the logic to write a JSON VFS mapping from the C api into VirtualFileSystem, so that we can use it internally. No functional change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@209241 91177308-0d34-0410-b5e6-96231b3b80d8

* [cleanup] Re-sort includes with llvm/utils/sort_includes.py and fixChandler Carruth2014-03-04
| | | | | | | | | | | | a missing include from CLog.h. CLog.h referenced most of the core libclang types but never directly included Index.h that provides them. Previously it got lucky and other headers were always included first but with the sorting it ended up first in one case and stopped compiling. Adding the Index.h include fixes it right up. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@202810 91177308-0d34-0410-b5e6-96231b3b80d8

* Reapply fixed "Honour 'use-external-names' in FileManager"Ben Langmuir2014-02-28
| | | | | | | | | | | | | | | | Was r202442 There were two issues with the original patch that have now been fixed. 1. We were memset'ing over a FileEntry in a test case. After adding a std::string to FileEntry, this still happened to not break for me. 2. I didn't pass the FileManager into the new compiler instance in compileModule. This was hidden in some cases by the fact I didn't clear the module cache in the test. Also, I changed the copy constructor for FileEntry, which was memcpy'ing in a (now) unsafe way. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@202539 91177308-0d34-0410-b5e6-96231b3b80d8

* Honour 'use-external-names' in FileManagerBen Langmuir2014-02-27
| | | | | | | | Pass through the externally-visible names that we got from the VFS down to FileManager, and test that this is the name showing up in __FILE__, diagnostics, and debug information. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@202442 91177308-0d34-0410-b5e6-96231b3b80d8
* Add a 'use-external-names' option to VFS overlay filesBen Langmuir2014-02-27
| | | | | | | | | | | | | | | | When true, sets the name of the file to be the name from 'external-contents'. Otherwise, you get the virtual path that the file was looked up by. This will not affect any non-virtual paths, or fully virtual paths (for which there is no reasonable 'external' name anyway). The setting is available globally, but can be overriden on a per-file basis. The goal is that this setting will control which path you see in debug info, diagnostics, etc. which are sensitive to which path is used. That will come in future patches that pass the name through to FileManager. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@202329 91177308-0d34-0410-b5e6-96231b3b80d8

* Pass through context for DiagHandler in VFSBen Langmuir2014-02-24
| | | | | | | This allows the unit tests to not use global state when checking diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@202072 91177308-0d34-0410-b5e6-96231b3b80d8
* Add a VFSFromYAML class and a parser to create itBen Langmuir2014-02-21
| | | | | | | | | | | | | | | Provides a way to create a virtual file system using a YAML file that supports mapping a file to a path on an 'external' file system. The external file system will typically be the 'real' file system, but for testing it can be changed. A future patch will add a clang option to allow the user to specify such a file and overlay it, but for now this code is only exercised by the unit tests.

* Recommit virtual file systemBen Langmuir2014-02-20
| | | | | | | | | | | Previously reverted in r201755 due to causing an assertion failure. I've removed the offending assertion, and taught the CompilerInstance to create a default virtual file system inside createFileManager. In the future, we should be able to reach into the CompilerInvocation to customize this behaviour without breaking clients that don't care. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@201818 91177308-0d34-0410-b5e6-96231b3b80d8
