2017-01-14Don't dump llvm-config --cmakedir output if command fails.Eric Fiselier
This patch adjusts the out-of-tree CMake configuration so that the stderr output is ignored when an old llvm-config is found that doesn't support --cmakedir. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@291991 91177308-0d34-0410-b5e6-96231b3b80d8

2017-01-13Add _LIBCPP_DIAGNOSE_WARNING and _LIBCPP_DIAGNOSE_ERROR macros.Eric Fiselier
Clang recently added a `diagnose_if(cond, msg, type)` attribute which can be used to generate diagnostics when `cond` is a constant expression that evaluates to true. Otherwise no attribute has no effect. This patch adds _LIBCPP_DIAGNOSE_ERROR/WARNING macros which use this new attribute. Additionally this patch implements a diagnostic message when a non-const-callable comparator is given to a container. Note: For now the warning version of the diagnostic is useless within libc++ since warning diagnostics are suppressed by the system header pragma. I'm going to work on fixing this. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@291961 91177308-0d34-0410-b5e6-96231b3b80d8

There is no guaranteed order in which CMake files for individual runtimes are invoked and therefore we cannot rely on existence of targets defined in other runtimes.

2017-01-09Move _PairT declaration out of __hash_combine to avoid warning under C++98Dimitry Andric
Summary: Some parts of the FreeBSD tree are still compiled with C++98, and until rL288554 this has always worked fine. After that, a complaint about the newly introduced local _PairT is produced: /usr/include/c++/v1/memory:3354:27: error: template argument uses local type '_PairT' [-Werror,-Wlocal-type-template-args] typedef __scalar_hash<_PairT> _HashT; ^~~~~~ /usr/include/c++/v1/memory:3284:29: error: template argument uses local type '_PairT' [-Werror,-Wlocal-type-template-args] : public unary_function<_Tp, size_t> ^~~ /usr/include/c++/v1/memory:3356:12: note: in instantiation of template class 'std::__1::__scalar_hash<_PairT, 2>' requested here return _HashT()(__p); ^ As far as I can see, there should be no problem moving the _PairT struct to just before the __hash_combine() function, which fixes this particular warning.

2017-01-07system_error: correct ELAST emulation on WindowsSaleem Abdulrasool
ELAST should point to the last valid error string value. However, `_sys_nerr` provides the number of elements in the errlist array. Since the index is 0-based, this is off-by-one.

Add an implementation for the Win32 threading model as a backing API for the internal c++ threading interfaces.

2017-01-07[libc++] Tolerate presence of __deallocate macroEric Fiselier
Summary: On Windows the identifier `__deallocate` is defined as a macro by one of the Windows system headers. Previously libc++ worked around this by `#undef __deallocate` and generating a warning. However this causes the WIN32 version of `__threading_support` to always generate a warning on Windows. This is not OK. This patch renames all usages of `__deallocate` internally as to not conflict with the macro.

2017-01-07thread: implement sleep_for on WindowsSaleem Abdulrasool
Windows does not provide an implementation of `nanosleep`. Round up the time duration to the nearest ms and use `Sleep`. Although this may over-sleep, there is no hard real-time guarantee on the wake, so sleeping a bit more is better than under-sleeping as it within the specification. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@291331 91177308-0d34-0410-b5e6-96231b3b80d8
