Use FD20 macro that will account for the implicit LSB zero value and is already used for sources. For the new macro we need to use the entire bit-range of the field (55-51), so remove the adjustments we used to do prior to encoding and decoding. Fixes assertion in vkpeak (https://github.com/nihui/vkpeak) when running bf16 tests on BMG. And the code now will correctly apply the subreg_nr to the destination, e.g. a mad(32) gets splitted into two pieces, the generation would not fill out the upper-part of the register ``` mad(16) g13<1>BF g10<8,8,1>BF g12<8,8,1>BF g56<1,1,1>F { align1 1H A@5 }; -mad(16) g13<1>BF g10.16<8,8,1>BF g12.16<8,8,1>BF g57<1,1,1>F { align1 2H A@5 }; +mad(16) g13.16<1>BF g10.16<8,8,1>BF g12.16<8,8,1>BF g57<1,1,1>F { align1 2H A@5 }; ``` Reviewed-by: Matt Turner <mattst88@gmail.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/37236> |

`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>`_).
