opt_copy_propagation can create invalid instructions like
shl(8) vgrf96:UD, 2d, 8u
These instructions will be cleaned up by opt_algebraic. The irony is
opt_algebraic converts these to simple mov instructions that
opt_copy_propagation should clean up. I don't think we want a loop like
do {
progress = false;
if (OPT(opt_copy_propagation)) {
OPT(opt_algebraic);
OPT(dead_code_eliminate);
}
} while (progress);
But maybe we do?
Maybe this would be sufficient:
while (OPT(opt_copy_propagation))
OPT(opt_algebraic);
OPT(dead_code_eliminate);
No shader-db or fossil-db changes (yet) on any Intel platform. This is
expected.
v2: Do opt_algebraic immediately after every call to
opt_copy_propagation instead of being clever. Suggested by Lionel.

`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 `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://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>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
