* Finishing touch for the std::error_code transition.Rafael Espindola2014-06-13
| | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210920 91177308-0d34-0410-b5e6-96231b3b80d8
* Use std::error_code instead of llvm::error_code.Rafael Espindola2014-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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++. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210687 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a unit test for the copy constructor.Rafael Espindola2014-01-09
| | | | | | | | I would not normally add tests like these, but the copy constructor is not used at all in our codebase with c++11, so having this tests might prevent breaking the c++03 build again. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198886 91177308-0d34-0410-b5e6-96231b3b80d8

Also comment and sink the include of "Windows.h" in three .inc files to match the usage in Memory.inc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198685 91177308-0d34-0410-b5e6-96231b3b80d8
* Simplify ErrorOr.Rafael Espindola2013-11-05
| | | | | | | | | | | | | | | | ErrorOr had quiet a bit of complexity and indirection to be able to hold a user type with the error. That feature is not used anymore. This patch removes it, it will live in svn history if we ever need it again. If we do need it again, IMHO there is one thing that should be done differently: Holding extra info in the error is not a property a function also returning a value or not. The ability to hold extra info should be in the error type and ErrorOr templated over it so that we don't need the funny looking ErrorOr<void>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194030 91177308-0d34-0410-b5e6-96231b3b80d8
