* Finishing touch for the std::error_code transition.Rafael Espindola2014-06-131-1/+2
| | | | | | | | | | | While std::error_code itself seems to work OK in all platforms, there are few annoying differences with regards to the std::errc enumeration. This patch adds a simple llvm enumeration, which will hopefully avoid build breakages in other platforms and surprises as we get more uses of std::error_code. llvm-svn: 210920
* Remove 'using std::errro_code' from lib.Rafael Espindola2014-06-131-9/+8
| | | | llvm-svn: 210871
* 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 system_error.h.Rafael Espindola2014-06-121-1/+1
| | | | | | | This is a minimal change to remove the header. I will remove the occurrences of "using std::error_code" in a followup patch. llvm-svn: 210803
* Don't import make_error_code into the llvm namespace.Rafael Espindola2014-06-121-1/+1

* Use std::error_code instead of llvm::error_code.Rafael Espindola2014-06-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Use error_code() instead of error_code::succes()Rafael Espindola2014-05-311-1/+1
| | | | | | | There is no std::error_code::success, so this removes much of the noise in transitioning to std::error_code. llvm-svn: 209952
* Remove last uses of OwningPtr from llvm. As far as I can tell these method ↵Craig Topper2014-05-181-11/+0
| | | | | | versions are not used by lldb, lld, or clang. llvm-svn: 209103
* [C++11] Make use of 'nullptr' in the Support library.Craig Topper2014-04-071-1/+1
| | | | llvm-svn: 205697
* [C++11] Add overloads for externally used OwningPtr functions.Ahmed Charles2014-03-051-3/+13
| | | | | | | | 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
* Use the simpler version of sys::fs::remove when possible.Rafael Espindola2014-01-101-4/+2
| | | | llvm-svn: 198958
* Create files with the correct permission instead of changing it afterwards.Rafael Espindola2013-07-081-22/+7
| | | | | | Not intended functionality change. llvm-svn: 185830
* Add a createUniqueFile function and switch llvm's users of unique_file.Rafael Espindola2013-07-051-2/+2
| | | | | | | | | | | | | | This function is complementary to createTemporaryFile. It handles the case were the unique file is *not* temporary: we will rename it in the end. Since we will rename it, the file has to be in the same filesystem as the final destination and we don't prepend the system temporary directory. This has a small semantic difference from unique_file: the default mode is 0666. This matches the behavior of most unix tools. For example, with this change lld now produces files with the same permissions as ld. I will add a test of this change when I port clang over to createUniqueFile (next commit). llvm-svn: 185726
* [Support] Fix lifetime of file descriptors when using MemoryBuffer.Michael J. Spencer2013-03-141-2/+2
| | | | | | | Clients of MemoryBuffer::getOpenFile expect it not to take ownership of the file descriptor passed in. So don't. llvm-svn: 176995
* [Support] Make FileOutputBuffer work on Windows.Michael J. Spencer2012-12-031-55/+27

* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-031-1/+0
| | | | | | | | | | | | | | | | | Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] llvm-svn: 169131
* Initial commit of new FileOutputBuffer support class. Nick Kledzik2012-08-011-0/+148
Since the llvm::sys::fs::map_file_pages() support function it relies on is not yet implemented on Windows, the unit tests for FileOutputBuffer are currently conditionalized to run only on unix. llvm-svn: 161099
