Stephan T. Lavavej d4b83e6dfd [libcxx] [test] D27269: Fix MSVC x64 warning C4267 "conversion from 'size_t' to 'int' [or 'unsigned int'], possible loss of data", part 3/4.

test/std/containers/sequences/vector.bool/copy_alloc.pass.cpp
test/std/containers/sequences/vector/vector.cons/copy.pass.cpp
test/std/containers/sequences/vector/vector.cons/copy_alloc.pass.cpp
Change "unsigned s = x.size();" to "typename C::size_type s = x.size();"
because that's what it returns.

test/std/strings/basic.string/string.cons/pointer_alloc.pass.cpp
Include <cstddef>, then change "unsigned n = T::length(s);"
to "std::size_t n = T::length(s);" because that's what char_traits returns.

test/std/strings/basic.string/string.cons/substr.pass.cpp
Change unsigned to typename S::size_type because that's what str.size() returns.

test/std/utilities/template.bitset/bitset.cons/ull_ctor.pass.cpp
This was needlessly truncating std::size_t to unsigned.
It's being used to compare and initialize std::size_t.

Use static_cast<int> when storing size_t in int (or passing size_t to int).

Also, remove a spurious semicolon in test/support/archetypes.hpp.

test/support/count_new.hpp
Additionally, change data members (and parameters) to size_t.

Replace "int n = str_.size();" with "int n = static_cast<int>(str_.size());".

int is the correct type to use, because we're eventually calling
"base::pbump(n+1);" where base is std::basic_streambuf.
N4606 27.6.3.3.3 [streambuf.put.area]/4 declares: "void pbump(int n);"

Stephan T. Lavavej e9c728899f [libcxx] [test] D27025: Fix MSVC warning C4389 "signed/unsigned mismatch", part 12/12.
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.

Stephan T. Lavavej 6859c20ac9 [libcxx] [test] D27024: Fix MSVC warning C4389 "signed/unsigned mismatch", part 11/12.
Change "unsigned n = 0;" to "int n = 0;". It's being compared to int elements and ptrdiff_t distances.

test/std/containers/sequences/forwardlist/forwardlist.cons/move.pass.cpp
This one's a little special, but not really. "*i == n" is comparing MoveOnly to n.
MoveOnly is implicitly constructible from int, so int is the correct type to use here.

Stephan T. Lavavej e17a155c61 [libcxx] [test] D27023: Fix MSVC warning C4389 "signed/unsigned mismatch", part 10/12.
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.

Stephan T. Lavavej 68a694b800 [libcxx] [test] D27022: Fix MSVC warning C4389 "signed/unsigned mismatch", part 9/12.
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.

Stephan T. Lavavej fbfb2ab63e [libcxx] [test] D27021: Fix MSVC warning C4389 "signed/unsigned mismatch", part 8/12.
Add static_cast<std::size_t> when comparing distance() to size().

These replacements were performed programmatically with regex_replace():

const vector<pair<regex, string>> reg_fmt = {
    { regex(R"(assert\((\w+)\.size\(\) == std::distance\((\w+, \w+)\)\))"),
        "assert($1.size() == static_cast<std::size_t>(std::distance($2)))" },
    { regex(R"(assert\(distance\((\w+\.begin\(\), \w+\.end\(\))\) == (\w+)\.size\(\)\))"),
        "assert(static_cast<std::size_t>(distance($1)) == $2.size())" },
    { regex(R"(assert\(std::distance\((\w+\.\w*begin\(\), \w+\.\w*end\(\))\) == (\w+)\.size\(\)\))"),
        "assert(static_cast<std::size_t>(std::distance($1)) == $2.size())" },
};

Also, include <cstddef> when it wasn't already being included.

Eric Fiselier 8e27c2b970 Allow enabling/disabling testing with module using env LIBCXX_USE_MODULES=1
The Clang modules implementation breaks enough that libc++ needs an easy way
to enable/disable using modules on the Zorg builders. Editing Zorg itself
requires a buildmaster restart which only happens weekly. This patch
allows LIBCXX_USE_MODULES to be used to enable/disable the feature,
allowing the buildslave to disable it as need be.

Eric Fiselier daf21c3f69 Adjust libc++ test infastructure to fully support modules
This patch overhalls the libc++ test format/configuration in order to fully support modules. By "fully support" I mean get almost all of the tests passing. The main hurdle for doing this is handling tests that `#define _LIBCPP_FOO` macros to test a different configuration. This patch deals with these tests in the following ways:

1. For tests that define single `_LIBCPP_ABI_FOO` macros have been annotated with `// MODULES_DEFINES: _LIBCPP_ABI_FOO`. This allows the test suite to define the macro on the command line so it uses a different set of modules.
2. Tests for libc++'s debug mode (which define custom `_LIBCPP_ASSERT`) are automatically detected by the test suite and are compiled and run with modules disabled.

This patch also cleans up how the `CXXCompiler` helper class handles enabling/disabling language features.

NOTE: This patch uses `LIT` features which were only committed to LLVM today. If this patch breaks running the libc++ tests you probably need to update LLVM.

Roger Ferrer Ibanez 4cb4b36aa2 Handle tests for noexcept that expect a false value
Under libcpp-no-exceptions, noexcept is trivially true. Some tests expect in
the usual setting to return false, so adjust them to expect true under
libcpp-no-exceptions.
