* Don't use 'using std::error_code' in include/llvm.Rafael Espindola2014-06-121-0/+1
| | | | | | This should make sure that most new uses use the std prefix. llvm-svn: 210835
* Remove unused has_magic.Rafael Espindola2014-06-111-3/+0
| | | | | | | This will allow inlining get_magic, which should in turn fix one of the mingw build problems after the switch to std::error_code. llvm-svn: 210712
* Use std::error_code instead of llvm::error_code.Rafael Espindola2014-06-111-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idea of this patch is to turn llvm/Support/system_error.h into a transitional header that just brings in the erorr_code api to the llvm namespace. I will remove it shortly afterwards. The cases where the general idea needed some tweaking: * std::errc is a namespace in msvc, so we cannot use "using std::errc". I could add an #ifdef, but there were not that many uses, so I just added std:: to them in this patch. * Template specialization had to be moved to the std namespace in this patch set already. * The msvc implementation of default_error_condition doesn't seem to provide the same transformations as we need. Not too surprising since the standard doesn't actually say what "equivalent" means. I fixed the problem by keeping our old mapping and using it at error_code construction time. Despite these shortcomings I think this is still a good thing. Some reasons: * The different implementations of system_error might improve over time. * It removes 925 lines of code from llvm already. * It removes 6313 bytes from the text segment of the clang binary when it is built with gcc and 2816 bytes when building with clang and libstdc++. llvm-svn: 210687
* Remove windows_error.Rafael Espindola2014-06-111-1/+5
| | | | | | | | | | MSVC doesn't seem to provide any is_error_code_enum enumeration for the windows errors. Fortunately very few places in llvm have to handle raw windows errors, so we can just construct the corresponding error_code directly. llvm-svn: 210631
* support: add a utility function to normalise path separatorsSaleem Abdulrasool2014-03-111-0/+37
| | | | | | | | Add a utility function to convert the Windows path separator to Unix style path separators. This is used by a subsequent change in clang to enable the use of Windows SDK headers on Linux. llvm-svn: 203611
* Cleanup the interface for creating soft or hard links.Rafael Espindola2014-03-111-2/+2
| | | | | | | | | | | | Before this patch the unix code for creating hardlinks was unused. The code for creating symbolic links was implemented in lib/Support/LockFileManager.cpp and the code for creating hard links in lib/Support/*/Path.inc. The only use we have for these is in LockFileManager.cpp and it can use both soft and hard links. Just have a create_link function that creates one or the other depending on the platform. llvm-svn: 203596
* Replace OwningPtr<T> with std::unique_ptr<T>.Ahmed Charles2014-03-061-2/+2
| | | | | | | | | | 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 Langmuir2014-03-051-0/+29
| | | | | | | | | 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] Switch all uses of the llvm_move macro to use std::moveChandler Carruth2014-03-021-1/+1
| | | | | | directly, and remove the macro. llvm-svn: 202612
* [C++11] Remove uses of LLVM_HAS_RVALUE_REFERENCES from the unittests.Chandler Carruth2014-03-011-2/+0
| | | | llvm-svn: 202583
* Replace the F_Binary flag with a F_Text one.Rafael Espindola2014-02-241-3/+3
| | | | | | | | | 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
* Fix windows unittest I missed in the raw_fd_ostream constructor change.Rafael Espindola2014-02-241-1/+1
| | | | llvm-svn: 202050
* Simplify remove, create_directory and create_directories.Rafael Espindola2014-02-231-17/+24
| | | | | | | | | | | | | | | 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
* Introduce llvm::sys::path::home_directory.Peter Collingbourne2014-01-311-0/+13
| | | | | | | | | This will be used by the line editor library to derive a default path to the history file. Differential Revision: http://llvm-reviews.chandlerc.com/D2199 llvm-svn: 200594

* Path: Recognize COFF import library file magic.Rui Ueyama2013-11-151-0/+2

* Recognize 0x0000 as a COFF file magic.Rui Ueyama2013-11-141-0/+2
| | | | | | | | | | | | | | | Summary: Some machine-type-neutral object files containing only undefined symbols actually do exist in the Windows standard library. Need to recognize them as COFF files. Reviewers: Bigcheese CC: llvm-commits Differential Revision: http://llvm-reviews.chandlerc.com/D2164 llvm-svn: 194734

* Fixes a bug when iterating on pathsTareq A. Siraj2013-08-121-0/+69
| | | | | | | | | This fixes the incorrect implementation of iterating on file/directory paths. Differential Review: http://llvm-reviews.chandlerc.com/D1277 llvm-svn: 188183
* Fix windows' implementation of status when a file doesn't exist.Rafael Espindola2013-07-311-0/+4
| | | | | | | | | The unix one was returning no_such_file_or_directory, but the windows one was return success. Update the one one caller that was depending on the old behavior. llvm-svn: 187463
* Implement getUniqueID for directories on windows.Rafael Espindola2013-07-301-0/+13
| | | | llvm-svn: 187441
* Include st_dev to make the result of getUniqueID actually unique.Rafael Espindola2013-07-291-3/+3
| | | | | | This will let us use getUniqueID instead of st_dev directly on clang. llvm-svn: 187378
* Don't end a file name with a dot. It looks odd.Rafael Espindola2013-07-251-0/+5
| | | | llvm-svn: 187124

| | | | llvm-svn: 186561
* Add a wrapper for open.Rafael Espindola2013-07-161-2/+1
| | | | | | | This centralizes the handling of O_BINARY and opens the way for hiding more differences (like how open behaves with directories). llvm-svn: 186447

| | | | llvm-svn: 185719
* Add a convenience createUniqueDirectory function.Rafael Espindola2013-06-271-5/+1
| | | | | | | | | | | There are a few valid situation where we care about the structure inside a directory, but not about the directory itself. A simple example is for unit testing directory traversal. PathV1 had a function like this, add one to V2 and port existing users of the created temp file and delete it hack to using it. llvm-svn: 185059
* Rename fs::GetUniqueID to fs::getUniqueID to match the style guide.Rafael Espindola2013-06-201-4/+4
| | | | llvm-svn: 184431
* Modified the implementation of fs::GetUniqueID on Windows such that it ↵Aaron Ballman2013-06-191-0/+36
| | | | | | actually finds a unique identifier for a file. Also adds unit tests for GetUniqueID. llvm-svn: 184351
* Move PathV2.h to Path.hRafael Espindola2013-06-111-1/+1
| | | | | | | Most clients have already been moved from Path V1 to V2. The ones using V1 now include PathV1.h explicitly. llvm-svn: 183801

* Switch LLVM_USE_RVALUE_REFERENCES to LLVM_HAS_RVALUE_REFERENCES.Chandler Carruth2012-11-301-1/+1
| | | | | | | | | | | | | | Rationale: 1) This was the name in the comment block. ;] 2) It matches Clang's __has_feature naming convention. 3) It matches other compiler-feature-test conventions. Sorry for the noise. =] I've also switch the comment block to use a \brief tag and not duplicate the name. llvm-svn: 168996
