NIR doesn't propagate precise through moves, and with NTT the
last output is usually preceded by a move, so that we no longer
see that the evaluation of some value is supposed to be exact,
and, hence we can't decorate the outputs accordingly.
Fixes with NTT:
dEQP-GLES31.functional.tessellation.common_edge.
triangles_equal_spacing_precise
triangles_fractional_odd_spacing_precise
triangles_fractional_even_spacing_precise
quads_equal_spacing_precise
quads_fractional_odd_spacing_precise
quads_fractional_even_spacing_precise
v2: Don't clear the precise flag when we hit a mov, because we may
hit a if/else construct like below and we don't track branches
IF X
TEMP[0] = OP_PRECICE ...
ELSE
TEMP[0] = MOV CONST[]
ENDIF
Thanks Emma for pointing out the problem.
v2: allocate precise handling flags to transform_prolog (Emma)

`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.
