[libc++] Refactor string unit tests to ease addition of new allocators

2023-09-27T13:01:58+00:00

While doing this, I also found a few tests that were either clearly
incorrect (e.g. testing the wrong function) or that lacked basic test
coverage like testing std::string itself (e.g. the test was only checking
std::basic_string with a custom allocator). In these cases, I did a few
conservative drive-by changes.

[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++] Replace _LIBCPP_HAS_NO_CONCEPTS with _LIBCPP_STD_VER > 17. NFCI.

2022-03-13T16:32:06+00:00

All supported compilers that support C++20 now support concepts. So, remove
`_LIB_LIBCPP_HAS_NO_CONCEPTS` in favor of `_LIBCPP_STD_VER > 17`. Similarly in
the tests, remove `// UNSUPPORTED: libcpp-no-concepts`.

[libcxx][test] the domain of == for forward iterators is iterator values from the same range

2022-01-24T21:00:07+00:00

* Default-initialized `basic_string` iterators are not portably in the domain of `==`.
* Avoid comparing iterators from non-equal string_views which MSVCSTL considers not to be in the domain of equality.
* Don't test invalid range `[in, out + N)`.

Also silence some truncation warnings by testing with a non-narrowing conversion.

[libc++] Fix __wrap_iter copy-assignment in constexpr contexts

2022-01-04T10:05:53+00:00

Fixes https://github.com/llvm/llvm-project/issues/52902

In debug mode during constant evaluation the iterator was never assigend. There seem to be no other instances of this bug.
