* 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
* MS ABI: Propagate class-level DLL attributes to class template ↵Hans Wennborg2014-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | specialization bases (PR11170) Consider the following code: template <typename T> class Base {}; class __declspec(dllexport) class Derived : public Base<int> {} When the base of an exported or imported class is a class template specialization, MSVC will propagate the dll attribute to the base. In the example code, Base<int> becomes a dllexported class. This commit makes Clang do the proopagation when the base hasn't been instantiated yet, and warns about it being unsupported otherwise. This is different from MSVC, which allows changing a specialization back and forth between dllimport and dllexport and seems to let the last one win. Changing the dll attribute after instantiation would be hard for us, and doesn't seem to come up in practice, so I think this is a reasonable limitation to have. MinGW doesn't do this kind of propagation. Differential Revision: http://reviews.llvm.org/D4264 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211725 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
* Objective-C. When we use @selector(save:), etc. there may be more Fariborz Jahanian2014-06-24
| | | | | | | | | | | | | | than one method with mismatched type of same selector name. clang issues a warning to point this out since it may cause undefined behavior. There are cases though that some APIs don't care about user methods and such warnings are perceived as noise. This patch allows users to add paren delimiters around selector name to turn off such warnings. So, @selector((save:)) will turn off the warning. It also provides 'fixit' so user knows what to do. // rdar://16458579 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211611 91177308-0d34-0410-b5e6-96231b3b80d8
* Add new debug kind LocTrackingOnly.Diego Novillo2014-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This new debug emission kind supports emitting line location information in all instructions, but stops code generation from emitting debug info to the final output. This mode is useful when the backend wants to track source locations during code generation, but it does not want to produce debug info. This is currently used by optimization remarks (-Rpass, -Rpass-missed and -Rpass-analysis). When one of the -Rpass flags is used, the front end will enable location tracking, only if no other debug option is enabled. To prevent debug information from being generated, a new debug info kind LocTrackingOnly causes DIBuilder::createCompileUnit() to not emit the llvm.dbg.cu annotation. This blocks final code generation from generating debug info in the back end. Depends on D4234.

* Avoid invalidating successfully loaded module filesBen Langmuir2014-06-20
| | | | | | | | | | | | | | | | | Successfully loaded module files may be referenced in other ModuleManagers, so don't invalidate them. Two related things are fixed: 1) I thought the last module in the manager was always the one that failed, but it isn't. So check explicitly against the list of vetted modules from ReadASTCore. 2) We now keep the file descriptor of pcm file open, which avoids the possibility of having two different pcms for the same module loaded when building in parallel with headers being modified during a build. <rdar://problem/16835846> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211330 91177308-0d34-0410-b5e6-96231b3b80d8

* Frontend: Add a CC1 flag to dump module dependencies to a directoryJustin Bogner2014-06-19
| | | | | | | | | | | | | | | | | | This adds the -module-dependency-dir to clang -cc1, which specifies a directory to copy all of a module's dependencies into in a form suitable to be used as a VFS using -ivfsoverlay with the generated vfs.yaml. This is useful for crashdumps that involve modules, so that the module dependencies will be intact when a crash report script is used to reproduce a problem on another machine. We currently encode the absolute path to the dump directory, due to limitations in the VFS system. Until we can handle relative paths in the VFS, users of the VFS map may need to run a simple search and replace in the file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211303 91177308-0d34-0410-b5e6-96231b3b80d8
