Howard Hinnant 24afdf71c1 Ruben Van Boxem: Turn islower_l and isupper_l into functions (instead of macros) on Windows only to quell a warning during libc++ building.

Howard Hinnant 98381453c0 Change <cwchar> and <cstring> to look out for flags which may or may not be set by the C headers <wchar.h> and <string.h> indicating C support for the C++-altered wcschr, wcspbrk, wcsrchr, wcsstr, wmemchr, strchr, strpbrk, strrchr, memchr, and strstr. This was already done in <cstring> for other platforms using other flags, so just had to add one more flag to the list there.

Howard Hinnant 1347d33451 The move / swap members were not correctly taking all of the possible states of the basic_stringbuf into account. Just rewrote these members. Test included. This fixes http://llvm.org/bugs/show_bug.cgi?id=15659.

Howard Hinnant 575e4e3650 Richard Smith: It was pointed out to me off-list that libc++'s non-compiler-builtin
implementation of std::is_polymorphic does this:

template <class _Tp> struct __is_polymorphic1 : public _Tp {};

... and that g++ rejects this if _Tp has an inaccessible virtual destructor
(because __is_polymorphic1<_Tp> would have a deleted virtual destructor
overriding _Tp's non-deleted destructor). Clang was failing to reject this;
I've fixed that in r178563, but that causes libc++'s corresponding test
case to fail with both clang and gcc when using the fallback
implementation. The fallback code also incorrectly rejects final types.

The attached patch fixes the fallback implementation of is_polymorphic; we
now use dynamic_cast's detection of polymorphic class types rather than
trying to determine if adding a virtual function makes the type larger:

  enable_if<sizeof((_Tp*)dynamic_cast<const volatile
void*>(declval<_Tp*>())) != 0, ...>

Two things of note here:
* the (_Tp*) cast is necessary to work around bugs in Clang and g++ where
we otherwise don't instantiate the dynamic_cast (filed as PR15656)
* the 'const volatile' is here to treat is_polymorphic<cv T> as true for a
polymorphic class type T -- my reading of the standard suggests this is
incorrect, but it matches our builtin __is_polymorphic and gcc

Howard Hinnant 5a13d8dcea Tighten up the iterator requirements for the vector member templates. This is especially important for the constructors so that is_constructible<vector<T>, I, I> gives the right answer when T can not be constructed from *I. Test case included for this latter point.

Howard Hinnant 92bd7c0337 Debug mode: learning to crawl. I need to set up some tests that actually test that the debug mode is working, but that won't cause problems when debug mode isn't on. This is my first prototype of such a test. It should call std::terminate() because it's comparing iterators from different containers. And std::terminate() is rigged up to exit normally. If debug mode fails, and doesn't call terminate, then the program asserts. The test is a no-op if _LIBCPP_DEBUG2 is not defined or is defined to be 0.

Howard Hinnant ead480d30a Change _LIBCPP_TYPE_VIS to use __type_visibility__(default) instead of __visibility__(default) when available. This change makes just the type_info visible so that types like vectors and strings can be used as exception objects across dylib boundaries even when hidden visibility is specified globally (at the command line), and yet this allows clients to hide the member functions of things like vector and string (with global visibility commands).

Howard Hinnant 2446649c1e Saleem Abdulrasool: If errno is defined as volatile int, the qualifier differences can cause
template typename deductions on swap<> (used in string.cpp).  Use
decltype(errno) to replicate the type and qualifier information for holding the
errno value.  Because errno is expected to be assignable, there is no need to
use typename std::remove_const<decltype(errno)>::type to hold the value.
