* [libcxx] Fix PR23589: std::function doesn't recognize null pointer to ↵Eric Fiselier2015-08-181-0/+247
| | | | | | | | | | | | | | | | | | | | 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.

* Checking more __invoke tests.Eric Fiselier2015-07-284-0/+1126
| | | | | | | Before I start trying to fix __invoke in C++03 it needs better test coverage. This patch adds a large amount of tests for __invoke. llvm-svn: 243366
* Cleanup <__functional_03>Eric Fiselier2015-07-229-0/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | <__functional_03> provides the C++03 definitions for std::memfun and std::function. However the interaction between <functional> and <__functional_03> is ugly and duplicates code needlessly. This patch cleans up how the two headers work together. The major changes are: - Provide placeholders, is_bind_expression and is_placeholder in <functional> for both C++03 and C++11. - Provide bad_function_call, function fwd decl, __maybe_derive_from_unary_function and __maybe_derive_from_binary_function in <functional> for both C++03 and C++11. - Move the <__functional_03> include to the bottom of <functional>. This makes it easier to see how <__functional_03> interacts with <functional> - Remove a commented out implementation of bind in C++03. It's never going to get implemented. - Mark almost all std::bind tests as unsupported in C++03. std::is_placeholder works in C++03 and C++11. std::is_bind_expression is provided in C++03 but always returns false. llvm-svn: 242870

It also changes most of the tests to use `bare_allocator` where possible instead of `test_allocator`.

| | | | | | std::unary_function or std::binary_function if there was only one (or two) parameters. Before C++11 shipped, this restiction was lifted, but libc++ still does this (which is fine). However, the tests still check for this outdated requiremnt. Change then to check for the nested typedefs instead (which are still required by the standard).

| | | | | | and the tests test for that. STL @ MS pointed out that the standard doesn't requie these objects to derive from unary_function, and so the tests should not require that either.

* Prevent ill-formed instantiation of __invoke_of<...> during the evaluation ↵Eric Fiselier2014-12-231-0/+49
| | | | | | | | | | | | | | | | of a bind expression. Fixes PR22003. The SFINAE on the function __mu(Fn, Args...) that evaluates nested bind expressions always tries to deduce the return type for Fn(Args...) even when Fn is not a nested bind expression. This can cause hard compile errors when the instantation of Fn(Args...) is ill-formed. This patch prevents the instantation of __invoke_of<Fn, Args...> unless Fn is actually a bind expression.

* [libcxx] Consolidate new/delete replacement in tests and disable it when ↵Eric Fiselier2014-12-229-235/+95
| | | | | | | | | | | | | | | | | | | | using sanitizers. Summary: MSAN and ASAN also replace new/delete which leads to a link error in these tests. Currently they are unsupported but I think it would be useful if these tests could run with sanitizers. This patch creates a support header that consolidates the new/delete replacement functionality and checking. When we are using sanitizers new and delete are no longer replaced and the checks always return true.
