The patch does several things: - fixes module exports - disables clang-tidy with Clang-17 due to known issues - disabled clang-tidy on older libstdc++ versions since it lacks C++20 features used - fixes the CMake dependency The issue why clang-tidy was not used in the CI was the last issue; the plugin was not a dependency of the tests. Without a plugin the tests disable clang-tidy. This was noticed while investigating https://github.com/llvm/llvm-project/issues/89898
The "module partitions" for the std module
The files in this directory contain the exported named declarations per header. These files are used for the following purposes:
- During testing exported named declarations are tested against the named declarations in the associated header. This excludes reserved names; they are not exported.
- Generate the module std.
These use cases require including the required headers for these "partitions" at different locations. This means the user of these "partitions" are responsible for including the proper header and validating whether the header can be loaded in the current libc++ configuration. For example "include " fails when locales are not available. The "partitions" use the libc++ feature macros to export the declarations available in the current configuration. This configuration is available if the user includes the `__config' header.
We use .inc files that we include from the top-level module instead of
using real C++ module partitions. This is a lot faster than module partitions,
see this for details.
