In some cases we will change the type of the destination register of an instruction. This is the type we should use to verify that we're allow to do the replacement. Otherwise we can hit restrictions on CHV and upcoming Xe-Hp for instance where the copy propagation transforms this : send(16) (mlen: 2) vgrf10:UD, 0u, 0u, vgrf35:D, null:UD mov(16) vgrf11:UW, vgrf10<2>:UW mov(16) vgrf12:UW, vgrf10+0.2<2>:UW mov(16) vgrf15:HF, |vgrf11|:HF mov(16) vgrf16:HF, |vgrf12|:HF mov(8) vgrf41<2>:UW, vgrf15+0.0:UW group0 mov(8) vgrf42<2>:UW, vgrf15+0.16:UW group8 mov(8) vgrf45<2>:UW, vgrf16+0.0:UW group0 mov(8) vgrf46<2>:UW, vgrf16+0.16:UW group8 into this : send(16) (mlen: 2) vgrf10:UD, 0u, 0u, vgrf35:D, null:UD mov(8) vgrf41<2>:HF, |vgrf10+0.0|<2>:HF group0 mov(8) vgrf42<2>:HF, |vgrf10+1.0|<2>:HF group8 mov(8) vgrf45<2>:HF, |vgrf10+0.2|<2>:HF group0 mov(8) vgrf46<2>:HF, |vgrf10+1.2|<2>:HF group8 Because of the floating point use, stride and offets should be the same. v2: Fix final destination type selection (Curro) v3: constify (Curro) Signed-off-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Cc: <mesa-stable@lists.freedesktop.org> Reviewed-by: Francisco Jerez <currojerez@riseup.net> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/9832>
`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://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <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.rst <https://mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://mesa3d.org/submittingpatches.html>`_).
