f33ffcc651 [modules] Add initial module map for libc++. 
git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@209265 91177308-0d34-0410-b5e6-96231b3b80d8

7fac8f6b9f Update cstddef after clang r207606. 
r207606 changed the __need_foo macros to behave like they do with gcc: If they
are set, _only_ the __need_foo stuff gets defined.  As a consequence, cstddef
no longer defined "offsetof".  It looks like the __need_foo defines aren't
needed anymore, so just remove them.

Fixes PR19723.

55622073f4 Exceptions store the message as reference counted string for 
compatibility to libstdc++. Move the implementation into a header for
easier sharing with libc++abi. Merge a number of improvements from that
version. Provide a POD definition for <stdexcept>'s public use to avoid
cast dances. Discussed with Marshall Clow.

7d4d519f0b Define a new macro in libc++ named '_LIBCPP_HAS_NO_ASAN'. When this is defined, 
libc++ will not call address_sanitizer to detect addressing errors in the
standard library containers. This is a negative macro to enable users to
disable the libc++ checks even if they are compiling with address sanitizer
enabled by defining this macro.

At the present time, there is no code in libc++ that looks at this macro.
That will come soon. This is just infrastructure.

9d3d032c7d Do not derive __gnu_cxx::hash<T> from std::hash<T>. 
Instead, define explicit specializations for the basic types listed in
the SGI documentation. This solves two problems:

 1) Helps avoid silent ODR violations caused by the absence of a
    user-supplied __gnu_cxx::hash specialization in cases where a std::hash
    specialization exists (e.g. for std::string).

 2) __gnu_cxx::hash semantics are slightly different to those of
    std::hash (for example, the former may dereference a pointer argument)
    so it is inappropriate for __gnu_cxx::hash to receive std::hash
    specializations by default.

Error 1 error C2681: 'add_rvalue_reference<_Tp*>::type' : invalid expression
type for dynamic_cast c:\libcxx\include\type_traits

This is one more step getting libcxx compile under Visual C++. The patch is 
#if defined(_LIBCPP_MSVC) so will affect only this build.

When libcxx can be compiled, it will probably require the current version or
maybe even the next Update of Visual C++ 2013.
