Always make sure to correctly deref and store a 64bits variable
from the right number of components.
This fixes the `spec@arb_enhanced_layouts@matching_fp64_types_`
piglit tests for virgl.
Corrects this validation issue:
```
decl_var INTERP_MODE_FLAT dvec2[] var_7@2
decl_var INTERP_MODE_FLAT dvec2[] var_7@3
...
vec1 32 ssa_302 = deref_var &var_7@2 (function_temp dvec2[])
vec1 32 ssa_303 = deref_var &var_7@3 (function_temp dvec2[])
vec1 32 ssa_304 = deref_array &(*ssa_302)[ssa_301] (function_temp dvec2) /* &var_7@2[ssa_301] */
vec1 32 ssa_305 = deref_array &(*ssa_303)[ssa_301] (function_temp dvec2) /* &var_7@3[ssa_301] */
vec1 64 ssa_306 = mov ssa_110.z

`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.
