Eric Fiselier 0d28f78401 [libcxx] Fix PR23589: std::function doesn't recognize null pointer to varargs function. ... Summary: This patch fixes __not_null's detection of nullptr by breaking it down into 4 cases. 1. `__not_null(Tp const&)`: Default case. Tp is not null. 2. `__not_null(Tp* __ptr);` Case for pointers to functions. 3. `__not_null(_Ret _Class::* __ptr);` Case for pointers to members. 4. `__not_null(function<Tp> const&);`: Cases for other std::functions.

arithmetic.operations	In C++03, a bunch of the arithmetic/logical/comparison functors (such as negate/bit_not.pass/logical_not) were defined as deriving from unary_funtion. That restriction was removed in C++11, but the tests still check for this. Change the test to look for the embedded types first_argument/second_argument/result_type. No change to the library, just more standards-compliant tests. Thanks to STL @ Microsoft for the suggestion.	2015-01-07 21:51:30 +00:00
