in scenarios like: vec1 32 ssa_151 = deref_var &shadow_map (uniform sampler2D) vec1 32 ssa_152 = deref_var &shadow_map (uniform sampler2D) vec2 32 ssa_153 = vec2 ssa_151, ssa_152 vec1 32 ssa_154 = deref_var ¶m@4 (function_temp uvec2) intrinsic store_deref (ssa_154, ssa_153) (wrmask=xy /*3*/, access=0) vec1 32 ssa_160 = deref_var ¶m@4 (function_temp uvec2) vec2 32 ssa_164 = intrinsic load_deref (ssa_160) (access=0) vec1 32 ssa_167 = mov ssa_164.x vec1 32 ssa_168 = deref_cast (texture2D *)ssa_167 (uniform texture2D) /* ptr_stride=0, align_mul=0, align_offset=0 */ vec1 32 ssa_169 = mov ssa_164.y vec1 32 ssa_170 = deref_cast (sampler *)ssa_169 (uniform sampler) /* ptr_stride=0, align_mul=0, align_offset=0 */ vec1 32 ssa_172 = (float32)tex ssa_168 (texture_deref), ssa_170 (sampler_deref), ssa_171 (coord), ssa_166 (comparator) the real variable is stored to a function_temp and then loaded back again, which means it isn't a direct deref and lower_vri_instr_tex_deref() will crash because the variable can't be found BUT running only the passes needed to eliminate derefs will break other tests, so just run the whole optimize loop again here to avoid such issues for #5945 Reviewed-by: Dave Airlie <airlied@redhat.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/15511> |

`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.
