Eric Fiselier 54519a6be9 [libcxx] Fix PR 22468 - std::function<void()> does not accept non-void-returning functions
Summary:
The bug can be found here: http://llvm.org/bugs/show_bug.cgi?id=22468

`__invoke_void_return_wrapper` is needed to properly handle calling a function that returns a value but where the std::function return type is void. Without this '-Wsystem-headers' will cause `function::operator()(...)` to not compile.

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
