For such issues, users can add references to ``N::g`` in the `module purview <https://eel.is/c++draft/module.unit#5>`_ of ``M.cppm`` to ensure it is reachable, e.g. ``using N::g;``. -Support for Reduced BMIs is still experimental, but it may become the default -in the future. The expected roadmap for Reduced BMIs as of Clang 19.x is: - -1. ``-fexperimental-modules-reduced-bmi`` was introduced in v19.x -2. For v20.x, ``-fmodules-reduced-bmi`` is introduced as an equivalent non-experimental - option. It is expected to stay opt-in for 1~2 releases, though the period depends - on user feedback and may be extended. -3. Finally, ``-fmodules-reduced-bmi`` will be the default. When that time - comes, the term BMI will refer to the Reduced BMI and the Full BMI will only - be meaningful to build systems which elect to support two-phase compilation. +As of Clang 22.x, the Reduced BMI is enabled by default. You may still want to +use Full BMI with ``-fno-modules-reduced-bmi`` in the following case: +1. Your build system uses two-phase compilation but it haven't adjusted the +implementation for reduced BMI. +2. You meet a regression with Reduced BMI that you cannot work around. Please +report an issue for this case. Experimental Non-Cascading Changes ---------------------------------- |
