2021-02-15Define new/delete in libc++ when using libcxxrtDimitry Andric2-0/+11
Always turn on LIBCXX_ENABLE_NEW_DELETE_DEFINITIONS, if libcxxrt is used as the C++ ABI library, since libcxxrt does not provide the full set ofnew and delete operators. In particular, the aligned versions of these operators are completely missing. This primarily addresses builds on FreeBSD, as this platform uses libcxxrt by default. Also, attempt to provide a FreeBSD.cmake cache file, with hopefully sane settings, partially copied from the Apple.cmake cache file. This needs more work, probably some additions to ci build scripts (although I am not aware of any 'official' FreeBSD build bots).

Currently all these tests are XFAILED on Linux even though the problem only seems to be with the few checks that look at collation. To retain test coverage this splits the locale-dependent tests into a separate .pass.cpp that is XFAILed as before. This commit also XFAILs the locale-dependent tests on FreeBSD since the [=M=] and [.ch.] behaviour for cs_CZ also doesn't seem to match the behaviour that is expected by these tests.

2021-01-19[libc++] Make LIBCXX_ENABLE_FILESYSTEM fully consistentLouis Dionne36-41/+155
Previously, LIBCXX_ENABLE_FILESYSTEM controlled only whether the filesystem support was compiled into libc++'s library. This commit promotes the setting to a first-class option like LIBCXX_ENABLE_LOCALIZATION, where the whole library is aware of the setting and features that depend on <filesystem> won't be provided at all. The test suite is also properly annotated such that tests that depend on <filesystem> are disabled when the library doesn't support it. This is an alternative to https://llvm.org/D94824, but also an improvement along the lines of LIBCXX_ENABLE_LOCALIZATION that I had been wanting to make for a while. Differential Revision: https://reviews.llvm.org/D94921
2021-01-19[libc++] Unbreak the debug modeLouis Dionne4-47/+104
When the Debug mode is enabled, we disable extern declarations because we don't want to use the functions compiled in the library, which might not have had the debug mode enabled when built. However, some extern declarations need to be kept, because code correctness depends on it. 31e820378b8a removed those declarations, which had the unintended consequence of breaking the debug build. This commit fixes that by re-introducing a separate macro for the required extern declarations, and adds a comment so that we don't fall into that trap in the future.

I've been playing a bit with the `generate_feature_test_macro_components.py` script and replaced some hardcoded values with extra code generation (generate ALL the things).

2021-01-12[libc++] Give extern templates default visibility on gccShoaib Meenai2-7/+1
Contrary to the current visibility macro documentation, it appears that gcc does handle visibility attribute on extern templates correctly, e.g. https://godbolt.org/g/EejuV7.

2021-01-12[libcxx] Avoid overflows in the windows __libcpp_steady_clock_now()Martin Storsjö2-1/+6
As freq.QuadValue can be in the range of 10000000 to 19200000, the multiplication before division makes the calculation overflow and wrap to negative values every 16-30 minutes. Instead count the whole seconds separately before adding the scaled fractional seconds. Add a testcase for steady_clock to check that the values returned for now() compare as bigger than the zero time origin; this corresponds to a testcase in Qt [1] [2] (that failed spuriously due to this).
