When initializing unsigned integers to their maximum values, change "const T M(~0);" to "const T M(static_cast<T>(-1));".
~0 and -1 are equivalent, but I consider the -1 form to be significantly clearer (and more consistent with other tests).
llvm-svn: 287827
Various changes:
test/std/algorithms/alg.sorting/alg.binary.search/binary.search/binary_search.pass.cpp
Change M from unsigned to int. It's compared against "int x",
and we binary_search() for it within a vector<int>.
test/std/numerics/rand/rand.dis/rand.dist.norm/rand.dist.norm.f/eval.pass.cpp
test/std/numerics/rand/rand.dis/rand.dist.norm/rand.dist.norm.f/eval_param.pass.cpp
Add static_cast<unsigned> when comparing int to unsigned.
test/std/strings/basic.string/string.cons/size_char_alloc.pass.cpp
Change unsigned indices to int when we're being given int as a bound.

Summary: The `max_size()` method of containers should respect both the allocator's reported `max_size` and the range of the `difference_type`. This patch makes all containers choose the smallest of those two values.

Summary:
Because `locale.h` isn't part of the libc++ modules the class definitions it provides are exported as part of `__locale` (since it happens to be build first). This breaks `<clocale>` which exports `std::lconv` without including `<__locale>`.
This patch implements `locale.h` to fix this issue, it also adds support for testing libc++ with modules.

In C++11 mode and newer, use real static_asserts.
In C++03 mode, min() and max() aren't constexpr, so use plain asserts.
One test triggers MSVC's warning C4310 "cast truncates constant value".
The code is valid, and yet the warning is valid, so I'm silencing it
through push-disable-pop.

sample() isn't specified with a reproducible algorithm, so expecting
exact output is non-Standard. Mark those tests with LIBCPP_ASSERT.
In test_small_population(), we're guaranteed to get all of the elements,
but not necessarily in their original order. When PopulationCategory is
forward, we're guaranteed stability (and can therefore test equal()).
Otherwise, we can only test is_permutation(). (As it happens, both libcxx
and MSVC's STL provide stability in this scenario for input-only iterators.)

The Standard doesn't provide any guarantees beyond "valid but unspecified" for
moved-from std::functions. libcxx moves from small targets and leaves them
there, while MSVC's STL empties out the source. Mark these assertions as
libcxx-specific.

N4582 17.6.3.5 [allocator.requirements] says that allocators are given
cv-unqualified object types, and N4582 20.9.9 [default.allocator]
implies that allocator<const T> is ill-formed (due to colliding
address() overloads). Therefore, tests for allocator<const T>
should be marked as libcxx-specific (if not removed outright).

This fails with gcc because __builtin_isnan and friends, which
libcpp_isnan and friends call, are not themselves constexpr-evaluatable.

Summary:
This makes these functions available on host and device, which is
necessary to compile <complex> for the device.

With a max_load_factor of 1.0, the only guarantee is that
bucket_count() >= size(). (Note: setting max_load_factor without
rehashing isn't supposed to affect this, because setting
max_load_factor is currently specified to be constant time.)
