| * Fix hash requirements check in __hash_table.Eric Fiselier2017-03-031-2/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | r296565 attempted to add better diagnostics when an unordered container is instantiated with a hash that doesn't meet the Hash requirements. However I mistakenly checked the wrong set of requirements. Specifically it checked if the hash met the requirements for specializations of std::hash. However these requirements are stricter than the generic Hash requirements. This patch fixes the assertions to only check the Hash requirements. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@296919 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | This patch adds a static assertion that the specified hash meets the requirements of an enabled hash, and it ensures that the static assertion is evaluated before __compressed_pair is instantiated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch implements [P0003R5](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0003r5.html) which removes exception specifications from C++17. The only changes to the library are removing `set_unexpected`, `get_unexpected`, `unexpected`, and `unexpected_handler`. These functions can be re-enabled in C++17 using `_LIBCPP_ENABLE_CXX17_REMOVED_UNEXPECTED_FUNCTIONS`. @mclow.lists what do you think about removing stuff is this way?

| * [libc++] Fix PR 31938 - std::basic_string constructors use non-deductible ↵Eric Fiselier2017-02-172-1/+302

Summary: This patch fixes http://llvm.org/PR31938. The description below is copy/pasted from the bug: The standard says: template<class charT, class traits = char_traits<charT>, class Allocator = allocator<charT>> class basic_string { using value_type = typename traits::char_type; // ... basic_string(const charT* s, const Allocator& a = Allocator()); }; libc++ actually chooses to declare the constructor as basic_string(const value_type* s, const Allocator& a = Allocator()); The implicit deduction guides from class template argument deduction make what was previously an implementation detail visible: std::basic_string s = "foo"; // error, can't deduce charT. The constructor in question is in the libc++ DSO, but fortunately it looks like fixing this will not result in an ABI break. @rsmith How does this look? I did more than just the constructors mentioned in the PR, but IDK how far to take it.
