test/std/algorithms/alg.modifying.operations/alg.generate/generate_n.pass.cpp
Silence MSVC warning C4244. This is expected when passing
floating-point values for size.
test/std/utilities/template.bitset/bitset.members/to_ullong.pass.cpp
test/std/utilities/template.bitset/bitset.members/to_ulong.pass.cpp
Avoid MSVC "warning C4293: '<<': shift count negative or too big,
undefined behavior". MSVC sees (1ULL << N) and warns - being guarded
by const bool canFit is insufficient. A small change to the code
avoids the warning without the need for a pragma.
Remove a spurious printf() declaration from to_ullong.pass.cpp.
Change ULL to UL in to_ulong.pass.cpp. The ULL suffix was
probably copy-pasted.
test/std/utilities/tuple/tuple.general/ignore.pass.cpp
Use LIBCPP_STATIC_ASSERT for consistency with other files.
test/support/container_test_types.h
Fix a null pointer dereference, found by MSVC /analyze
warning C6011 "Dereferencing NULL pointer 'm_expected_args'."
Fixes D41030.

This makes them consistent (many comments already used uppercase).
The special REQUIRES, UNSUPPORTED, and XFAIL comments are excluded from this change.

test/std/algorithms/alg.modifying.operations/alg.random.shuffle/random_shuffle_rand.pass.cpp
(Affects 64-bit architectures.) Include <cstddef> so we can take/return std::ptrdiff_t
(instead of int) in random_shuffle()'s RNG. (C++14 D.12 [depr.alg.random.shuffle]/2 says that
difference_type is used, and we're shuffling a plain array.)
test/std/algorithms/alg.sorting/alg.sort/sort/sort.pass.cpp
test/std/algorithms/alg.sorting/alg.sort/stable.sort/stable_sort.pass.cpp
(Affects 64-bit architectures.) Include <iterator> because we're already using iterator_traits.
Then, store the result of subtracting two RanIts as difference_type instead of long
(which truncates on LLP64 architectures like MSVC x64).
test/std/containers/sequences/forwardlist/forwardlist.ops/splice_after_flist.pass.cpp
test/std/containers/sequences/forwardlist/forwardlist.ops/splice_after_one.pass.cpp
(Affects 64-bit architectures.) Include <cstddef> so we can store the result of
subtracting two pointers as std::ptrdiff_t (instead of int).
test/std/input.output/iostream.format/input.streams/istream.unformatted/ignore_0xff.pass.cpp
(Affects 32-bit architectures.) Sometimes, size_t is too small. That's the case here,
where tellg() returns pos_type (N4606 27.7.2.3 [istream.unformatted]/39). Implementations can
have 64-bit pos_type (to handle large files) even when they have 32-bit size_t.
Fixes D27543.

Various changes:
test/std/algorithms/alg.sorting/alg.merge/inplace_merge.pass.cpp
This is comparing value_type to unsigned. value_type is sometimes int and sometimes struct S (implicitly constructible from int).
static_cast<value_type>(unsigned) silences the warning and doesn't do anything bad (as the values in question are small).
test/std/algorithms/alg.sorting/alg.nth.element/nth_element_comp.pass.cpp
This is comparing an int remote-element to size_t. The values in question are small and non-negative,
so either type is fine. I think that converting int to size_t is marginally better here than the reverse.
test/std/containers/sequences/deque/deque.cons/size.pass.cpp
DefaultOnly::count is int (and non-negative). When comparing to unsigned, use static_cast<unsigned>.
test/std/strings/basic.string/string.access/index.pass.cpp
We're comparing char to '0' through '9', but formed with the type size_t. Add static_cast<char>.
test/std/utilities/template.bitset/bitset.cons/ull_ctor.pass.cpp
Include <cstddef> for pedantic correctness (this test was already mentioning std::size_t).
"v[i] == (i & 1)" was comparing bool to size_t. Saying "v[i] == ((i & 1) != 0)" smashes the RHS to bool.

Add static_cast<int>. In these cases, the values are guaranteed to be small-ish,
and they're being compared to int elements.
test/std/containers/sequences/deque/deque.capacity/access.pass.cpp
Use int instead of unsigned to iterate from 0 to 10.
git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@288747 91177308-0d34-0410-b5e6-96231b3b80d8
Add static_cast<std::size_t> to more comparisons. (Performed manually, unlike part 8/12.)
Also, include <cstddef> when it wasn't already being included.
git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@288746 91177308-0d34-0410-b5e6-96231b3b80d8
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.
git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@287825 91177308-0d34-0410-b5e6-96231b3b80d8
Add static_cast<std::size_t> when comparing int to std::size_t.
Also, include <cstddef> when it wasn't already being included.
git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@287822 91177308-0d34-0410-b5e6-96231b3b80d8
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.)

This patch implements the std::sample function added to C++17 from LFTS. It
also removes the std::experimental::sample implementation which now forwards
to std::sample.
git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@279948 91177308-0d34-0410-b5e6-96231b3b80d8
Libc++'s implementation of shuffle and sample already support lvalue and rvalue
RNG's. This patch adds tests for both categories and marks the issue as complete.
This patch also contains drive-by change for std::experimental::sample which
improves the diagnostics produced when the correct iterator categories are
not supplied.
