You were allowed to pass in any old temp so that you could hopefully fold the PF up into the def of the temp. If we couldn't find one, it implicitly generated a MOV(nop, reg). However, that PF could have different behavior depending on whether the def being folded into was a float or int opcode, which the caller doesn't necessarily control. Due to the fragility of the function, just switch all callers over to vir_set_pf(). This also encourages the callers to use a _dest call for the inst they're putting the PF on, eliminating a bunch of temps in the pre-optimization VIR. shader-db says the change is in the noise: total instructions in shared programs: 6226247 -> 6227184 (0.02%) instructions in affected programs: 851068 -> 852005 (0.11%)

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.
