* Replace OwningPtr with std::unique_ptr.Ahmed Charles2014-03-071-10/+10
| | | | | | This compiles cleanly with lldb/lld/clang-tools-extra/llvm. llvm-svn: 203279
* Change OwningPtr::take() to OwningPtr::release().Ahmed Charles2014-03-071-1/+1
| | | | | | This is a precursor to moving to std::unique_ptr. llvm-svn: 203275
* Attempt to re-enable the VFS unittests on WindowsBen Langmuir2014-03-051-2/+4
| | | | | | | Using a //net/ path to hopefully avoid problems with non-absolute paths on Windows. llvm-svn: 203010
* Support relative paths in VFSFromYAMLBen Langmuir2014-03-041-3/+10
| | | | | | | | | Use llvm::sys::fs::make_absolute to get an absolute path before matching. Also, allow "." directories to enable testing. ".." is still not supported, and will require crossing file system boundaries to implement correctly. llvm-svn: 202903

* Reapply fixed "Honour 'use-external-names' in FileManager"Ben Langmuir2014-02-281-8/+29
| | | | | | | | | | | | | | | | 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. llvm-svn: 202539
* Revert "Honour 'use-external-names' in FileManager"Ben Langmuir2014-02-271-29/+8
| | | | | | Revert r202442, which broke the buildbots. llvm-svn: 202443
* Honour 'use-external-names' in FileManagerBen Langmuir2014-02-271-8/+29
| | | | | | | | 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. llvm-svn: 202442
* Add a 'use-external-names' option to VFS overlay filesBen Langmuir2014-02-271-15/+46
| | | | | | | | | | | | | | | | 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. llvm-svn: 202329
* Add a driver option -ivfsoverlayBen Langmuir2014-02-251-1/+1
| | | | | | | Reads the description of a virtual filesystem from a file and overlays it over the real file system. llvm-svn: 202176
* Allow multi-component paths in VFS file nodesBen Langmuir2014-02-251-20/+31
| | | | | | | | | | | | | | | | This allows the 'name' field to contain a path, like { 'type': 'directory', 'name': '/path/to/dir', 'contents': [ ... ] } which not only simplifies reading and writing these files (for humans), but makes it possible to easily modify locations via textual replacement, which would not have worked in the old scheme. E.g. sed s:<ROOT>:<NEW ROOT> llvm-svn: 202109
* Pass through context for DiagHandler in VFSBen Langmuir2014-02-241-2/+5
| | | | | | | This allows the unit tests to not use global state when checking diagnostics. llvm-svn: 202072
* Silence a warning from r201905Ben Langmuir2014-02-221-0/+1
| | | | | | | Avoid a warning about reaching the end of a non-void function after a covered switch. llvm-svn: 201919
* Add a VFSFromYAML class and a parser to create itBen Langmuir2014-02-211-4/+576
| | | | | | | | | | | | | | | 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 Langmuir2014-02-201-0/+193
| | | | | | | | | | | 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. llvm-svn: 201818
* Reverting the virtual file system implementation, because it triggers an ↵Juergen Ributzka2014-02-201-193/+0

* Reduce verbosity in the virtual file system using LLVM.hBen Langmuir2014-02-191-8/+6
| | | | | | No functional change llvm-svn: 201696

* Add an OverlayFileSystem classBen Langmuir2014-02-191-0/+33
| | | | | | | Provides a way to merge multiple vfs::FileSystem objects into a single filesystem. llvm-svn: 201635
* Initial implementation of virtual file systemBen Langmuir2014-02-191-0/+162
This adds the minimum virtual file system support to start migrating FileManager onto the VFS. Originally discussed here: http://lists.cs.uiuc.edu/pipermail/cfe-dev/2014-February/035188.html Differential Revision: http://llvm-reviews.chandlerc.com/D2745 llvm-svn: 201618
