This pass tries to fold f2f16 conversion into alu instructions. This will be useful to help reduce the number of instructions once mesa starts supporting precision lowering. For example: add.f r0.w, r0.w, c0.x cov.f32f16 hr2.x, r0.w to add.f hr2.x, r0.w, c0.x Additionally this pass also tries to fold f2f16 conversion into load_input instruction: bary.f r0.x, 3, r0.w cov.f32f16 hr0.x, r0.x to bary.f hr1.x, 3, r0.x v2: Edit to not fold OPC_MAX_F and OPC_MIN_F, since that's not valid. v3: Add OPC_ABSNEG_F to the blacklist as well. v4: Don't remove dead cov instructions, DCE will do that later; don't iterate through sources when a cov only has one; remove special handling of IR3_REG_ARRAY and IR3_REG_RELATIV. v5: Handle folding into u32.u32 movs of floats correctly, don't bail out on IR3_REG_RELATIV or IR3_REG_ARRAY movs. Part-of: <https://gitlab.freedesktop.org/mesa/mesa/merge_requests/3822>
`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.html <https://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.html <https://mesa3d.org/meson.html>`_): .. code-block:: sh $ mkdir build $ cd build $ meson .. $ sudo ninja install Support ------- Many Mesa devs hang on IRC; if you're not sure which channel is appropriate, you should ask your question on `Freenode's #dri-devel <irc://chat.freenode.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.html <https://mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.html <https://mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
