[libc++] Add an initial modulemap for the test support headers (#162800)

2025-11-13T08:28:48+00:00

This should improve the time it takes to run the test suite a bit. Right
now there are only a handful of headers in the modulemap because we're
missing a lot of includes in the tests. New headers should be added
there from the start, and we should fill up the modulemap over time
until it contains all the test support headers.

[libc++] Apply clang formatting to all string unit tests

2023-09-01T17:35:18+00:00

This applies clang-format to the std::string unit tests in preparation
for landing https://reviews.llvm.org/D140550.

[libcxx][AIX] Switch build compiler to clang

2022-06-14T01:45:18+00:00

This patch switches the build compiler for AIX from ibm-clang to clang. ibm-clang++_r has `-pthread` by default, but clang for AIX doesn't, so `-pthread` had to be added to the test config. A bunch of tests now pass, so the `XFAIL` was removed. This patch also switch the build to use the visibility support available in clang-15 to control symbols exported by the shared library (AIX traditionally uses explicit export lists for this purpose).

[libc++] Tidy up tests for deduction guides and other compile-time failing properties in std::string

2022-04-05T14:52:52+00:00

Instead of using `.fail.cpp` tests, use `.verify.cpp` to check for the
exact reason of the failure. In the case of deduction guides, use SFINAE
based tests instead since that is our preferred way of testing those.

Finally, ensure that we actually run the test in `iter_alloc_deduction.pass.cpp`,
since we were not running anything before.

[libc++] Add an option to disable wide character support in libc++

2021-10-12T10:08:23+00:00

Some embedded platforms do not wish to support the C library functionality
for handling wchar_t because they have no use for it. It makes sense for
libc++ to work properly on those platforms, so this commit adds a carve-out
of functionality for wchar_t.

Unfortunately, unlike some other carve-outs (e.g. random device), this
patch touches several parts of the library. However, despite the wide
impact of this patch, I still think it is important to support this
configuration since it makes it much simpler to port libc++ to some
embedded platforms.

[libc++] Remove workarounds for the lack of deduction guides in C++17

2021-08-18T12:57:25+00:00

All supported compilers have supported deduction guides in C++17 for a
while, so this isn't necessary anymore.

[libcxx][nfc] prefixes test type `input_iterator` with `cpp17_`

2021-05-02T05:02:59+00:00

C++20 revised the definition of what it means to be an iterator. While
all _Cpp17InputIterators_ satisfy `std::input_iterator`, the reverse
isn't true. D100271 introduces a new test adaptor to accommodate this
new definition (`cpp20_input_iterator`).

In order to help readers immediately distinguish which input iterator
adaptor is _Cpp17InputIterator_, the current `input_iterator` adaptor
has been prefixed with `cpp17_`.
