We currently have BITSET_*_RANGE macros which take a closed interval/range: a start bit and an end bit. Occassionally that is what you want, but most of the time callers actually want a start and a length. For example, register allocators will often do operations at (variable start register, variable start register + variable size - 1). It's more convenient to just take a start and a size, while also making the size=0 case well-defined as a no-op set/clear and false for test. This patch adds BITSET_*_COUNT macros aliasing to the existing range macros, and the rest of the series converts many call sites across the tree to use the new macros. Of the few call sites not converted, a whole bunch look like off-by-one bugs which I did not want to "fix" here and risk breaking something else. Probably worth checking your driver if you have RANGE calls leftover after this series. Also, aco and dozen both open-coded RANGE helpers that should probably be switched to the common code but that's neither here nor there.

`Mesa <https://mesa3d.org>`_ - The 3D Graphics Library ====================================================== Source ------ This repository lives at https://gitlab.freedesktop.org/mesa/mesa. Other repositories are likely forks, and code found there is not supported. Build & install --------------- You can find more information in our documentation (`docs/install.rst <https://docs.mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_): .. code-block:: sh $ meson setup build $ ninja -C build/ $ sudo ninja -C build/ install Support ------- Many Mesa devs hang on IRC; if you're not sure which channel is appropriate, you should ask your question on `OFTC's #dri-devel <irc://irc.oftc.net/dri-devel>`_, someone will redirect you if necessary. Remember that not everyone is in the same timezone as you, so it might take a while before someone qualified sees your question. To figure out who you're talking to, or which nick to ping for your question, check out `Who's Who on IRC <https://dri.freedesktop.org/wiki/WhosWho/>`_. The next best option is to ask your question in an email to the mailing lists: `mesa-dev\@lists.freedesktop.org <https://lists.freedesktop.org/mailman/listinfo/mesa-dev>`_ Bug reports ----------- If you think something isn't working properly, please file a bug report (`docs/bugs.rst <https://docs.mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://docs.mesa3d.org/submittingpatches.html>`_).
