* Replace OwningPtr<T> with std::unique_ptr<T>.Ahmed Charles2014-03-069-28/+17
| | | | | | | | | | This compiles with no changes to clang/lld/lldb with MSVC and includes overloads to various functions which are used by those projects and llvm which have OwningPtr's as parameters. This should allow out of tree projects some time to move. There are also no changes to libs/Target, which should help out of tree targets have time to move, if necessary. llvm-svn: 203083
* Fix an inconsistency in treatment of trailing / in path::const_iteratorBen Langmuir2014-03-051-8/+5
| | | | | | | | | When using a //net/ path, we were transforming the trailing / into a '.' when the path was just the root path and we were iterating backwards. Forwards iteration and other kinds of root path (C:\, /) were already correct. llvm-svn: 202999
* [C++11] Add overloads for externally used OwningPtr functions.Ahmed Charles2014-03-052-23/+81
| | | | | | | | This will allow external callers of these functions to switch over time rather than forcing a breaking change all a once. These particular functions were determined by building clang/lld/lldb. llvm-svn: 202959
* [C++11] Replace OwningPtr::take() with OwningPtr::release().Ahmed Charles2014-03-051-1/+1

* [Modules] Move the ConstantRange class into the IR library. This isChandler Carruth2014-03-042-735/+0
| | | | | | | | | | a bit surprising, as the class is almost entirely abstracted away from any particular IR, however it encodes the comparsion predicates which mutate ranges as ICmp predicate codes. This is reasonable as they're used for both instructions and constants. Thus, it belongs in the IR library with instructions and constants. llvm-svn: 202838
* [C+11] Add 'override' keyword to methods in the support library.Craig Topper2014-03-041-1/+1

* Revert "[C++11] Replace LLVM atomics with std::atomic."Benjamin Kramer2014-03-034-7/+8
| | | | | | | Breaks the MSVC build. DataStream.cpp(44): error C2552: 'llvm::Statistic::Value' : non-aggregates cannot be initialized with initializer list llvm-svn: 202731
* [C++11] Replace LLVM atomics with std::atomic.Benjamin Kramer2014-03-034-8/+7
| | | | | | | | | | | With C++11 we finally have a standardized way to specify atomic operations. Use them to replace the existing custom implemention. Sadly the translation is not entirely trivial as std::atomic allows more fine-grained control over the atomicity. I tried to preserve the old semantics as well as possible.

* [C++11] Replace llvm::tie with std::tie.Benjamin Kramer2014-03-022-2/+2
| | | | | | The old implementation is no longer needed in C++11. llvm-svn: 202644

* Fix RWMutex to be thread-safe when pthread_rwlock is not availableMark Seaborn2014-03-011-6/+14
| | | | | | | | | | | | | | lib/Support/RWMutex.cpp contains an implementation of RWMutex that uses pthread_rwlock, but when pthread_rwlock is not available (such as under NaCl, when using newlib), it silently falls back to using the no-op definition in lib/Support/Unix/RWMutex.inc, which is not thread-safe. Fix this case to be thread-safe by using a normal mutex. Differential Revision: http://llvm-reviews.chandlerc.com/D2892 llvm-svn: 202570
* CommandLine: Exit successfully for -version and -helpJustin Bogner2014-02-281-3/+3
| | | | | | | | | | | Tools that use the CommandLine library currently exit with an error when invoked with -version or -help. This is unusual and non-standard, so we'll fix them to exit successfully instead. I don't expect that anyone relies on the current behaviour, so this should be a fairly safe change. llvm-svn: 202530

* [CMake] Use target_link_libraries(INTERFACE|PRIVATE) on CMake-2.8.12 to ↵NAKAMURA Takumi2014-02-261-1/+1
| | | | | | | | | | | | | | | | | | increase opportunity for parallel build. target_link_libraries(INTERFACE) doesn't bring inter-target dependencies in add_library, although final targets have dependencies to whole dependent libraries. It makes most libraries can be built in parallel. target_link_libraries(PRIVATE) is used to shaared library. Each dependent library is linked to the target.so, and its user will not see its grandchildren. For example, - libclang.so has sufficient libclang*.a(s). - c-index-test requires just only libclang.so. FIXME: lld is tweaked minimally. Adding INTERFACE in each library would be better thing. llvm-svn: 202241

* Replace the F_Binary flag with a F_Text one.Rafael Espindola2014-02-244-7/+7
| | | | | | | | | After this I will set the default back to F_None. The advantage is that before this patch forgetting to set F_Binary would corrupt a file on windows. Forgetting to set F_Text produces one that cannot be read in notepad, which is a better failure mode :-) llvm-svn: 202052

* Simplify remove, create_directory and create_directories.Rafael Espindola2014-02-233-52/+34
| | | | | | | | | | | | | | | Before this patch they would take an boolean argument to say if the path already existed. This was redundant with the returned error_code which is able to represent that. This allowed for callers to incorrectly check only the existed flag instead of first checking the error code. Instead, pass in a boolean flag to say if the previous (non-)existence should be an error or not. Callers of the of the old simple versions are not affected. They still ignore the previous (non-)existence as they did before. llvm-svn: 201979

* Simplify linking to system librariesNAKAMURA Takumi2014-02-231-2/+26
| | | | | | | | | | | | | | | | | | | | | | | | | The LLVMSupport library implementation consolidates all dependencies on system libraries. Move the logic gathering system libraries out of 'cmake/modules/LLVM-Config.cmake' and into 'lib/Support/CMakeLists.txt'. Use the target_link_libraries() command there to tell CMake about the link dependencies of the LLVMSupport implementation. CMake will automatically propagate this to all targets that link LLVMSupport directly or indirectly. We still need to build knowledge of system library dependencies into 'llvm-config'. Store the list of libraries needed in a property on LLVMSupport and teach 'tools/llvm-config/CMakeLists.txt' to retrieve it from there. Drop all calls to 'link_system_libs' and 'get_system_libs' from our CMake code. Replace their implementations with a warning that explains the calls are no longer necessary. Also drop from 'LLVMConfig.cmake' the HAVE_* and related variables that were published there only to allow 'get_system_libs' to run outside our build process.

* Use mkdir instead of stat+mkdir.Rafael Espindola2014-02-131-11/+18
| | | | | | | | | | | | | This is an optimistic version of create_diretories: it tries to create the directory first and looks at the parent only if that fails. Running strace on "mkdir -p" shows that it is pessimistic, calling mkdir on every element of the path. We could implement that if needed. In any case, with both strategies there is no reason to call stat, just check the return of mkdir. llvm-svn: 201347

* Windows/Path.inc: Move <shlobj.h> after "Windows.h" for some API available.NAKAMURA Takumi2014-02-121-2/+3
| | | | | | | | | | | | | | | I found that swapping the order of some header files helped fix a build issue that we're seeing on mingw32. Without the swap, windows.h was being included before _WIN32_WINNT was being defined and the CreateHardLinkW function was #ifdef'd out. It looks like the header is mainly used to get the SHGetFolderPathW function, so I don't think that there'll be much fallout from the switch. Suggested by Alex Crichton. Thanks! llvm-svn: 201230

* Fix an invalid check for duplicate option categories.Alexander Kornienko2014-02-051-3/+14
| | | | | | | | | | | | | | | | | | | | Summary: The check performed in the comparator is invalid, as some STL implementations enforce strict weak ordering by calling the comparator with the same value. This check was also in a wrong place: the assertion would only fire when -help was used. The new check is performed each time the category is registered (we are not going to have thousands of them, so it's fine to do it in O(N^2)).
