Don't try to chase across blocks to find a matching destination for a given source. This can be prone to exponential blowup when there is a complicated series of if-ladders and we have to crawl through every possible path. With scalar ALU, this was causing timeouts on one test when we stopped counting scalar ALU. Rather than adding yet more band-aids, just switch to a different approach that most other backends are using where we have a scoreboard of outstanding registers and we keep track of the cycle when each register becomes "ready". This integrates nicely into the pre-existing ir3 legalize infrastructure for (ss) and (sy), although it does require duplicating the logic in ir3_delayslots() in a different form.

`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.
