* [libcxx] [test] D27267: Fix MSVC x64 warning C4267 "conversion from 'size_t' ↵Stephan T. Lavavej2016-12-0635-35/+35
| | | | | | | | | | | | to 'int' [or 'unsigned int'], possible loss of data", part 1/4. 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);" llvm-svn: 288751

* [libcxx] [test] D27025: Fix MSVC warning C4389 "signed/unsigned mismatch", ↵Stephan T. Lavavej2016-12-065-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 288749
* [libcxx] [test] D27024: Fix MSVC warning C4389 "signed/unsigned mismatch", ↵Stephan T. Lavavej2016-12-067-17/+17
| | | | | | | | | | | | 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. llvm-svn: 288748
* [libcxx] [test] D27023: Fix MSVC warning C4389 "signed/unsigned mismatch", ↵Stephan T. Lavavej2016-12-066-15/+15
| | | | | | | | | | | | 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. llvm-svn: 288747
* [libcxx] [test] D27022: Fix MSVC warning C4389 "signed/unsigned mismatch", ↵Stephan T. Lavavej2016-12-0623-49/+69
| | | | | | | | | | 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. llvm-svn: 288746
* [libcxx] [test] D27021: Fix MSVC warning C4389 "signed/unsigned mismatch", ↵Stephan T. Lavavej2016-12-06117-943/+1046
| | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 288745
* Adjust libc++ test infastructure to fully support modulesEric Fiselier2016-12-0524-55/+39
| | | | | | | | | | | | 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. llvm-svn: 288728

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

* [libcxx] [test] D26812: In random tests, use real static_asserts and silence ↵Stephan T. Lavavej2016-11-186-20/+84
| | | | | | | | | | | | | a warning. 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. llvm-svn: 287391
* [libcxx] [test] D26816: Fix non-Standard assumptions when testing sample().Stephan T. Lavavej2016-11-181-3/+14
| | | | | | | | | | | | | 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.) llvm-svn: 287383
* [libcxx] [test] D26815: Fix an assumption about the state of moved-from ↵Stephan T. Lavavej2016-11-181-2/+2
| | | | | | | | | | | std::functions. 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. llvm-svn: 287382
* [libcxx] [test] D26813: allocator<const T> is non-Standard.Stephan T. Lavavej2016-11-182-18/+18
| | | | | | | | | | 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). llvm-svn: 287381
