We currently convert it twice for unknown reasons, first when translating from TGSI and later in constant folding. Not only is this unnecessary, the first translation doesn't check for non-native swizzles, so removing it actually saves few instructions and gains a single Unigine shader for R300 at the expense of few more constant loads and temps. Also fixes few dEQPs because we could previously generate code like TEX temp[1], none.01__, 2D[0]; and the native swizzle rewrite pass was not ready for it.

`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.
