ir3_nir_lower_tex_prefetch expects src0 of load_interpolated_input to be intrinsic, however this assumption broke when src0 is load_barycentric_at_offset and is lowered in series of alu instructions. 32x2 %1121 = @load_barycentric_at_offset (%1120) (interp_mode=0) 32x4 %1118 = @load_interpolated_input (%1121, %1116 (0x0)) ... 32x2 %32 = vec2 %1118.x, %1118.y 32x4 %37 = (float32)tex %36 (texture_handle), %34 (sampler_handle), %32 (coord), 0 (texture), 0 (sampler) is lowered into: [...] 32 %54 = ffma %46.y, %52, %50 32 %55 = ffma %46.y, %53, %51 32x2 %56 = vec2 %54, %55 32x4 %57 = @load_interpolated_input (%56, %25 (0x0)) [...] Crash backtrace: #5 in __GI___assert_fail (assertion=0x7ff6692328 "parent && parent->type == nir_instr_type_intrinsic", file=0x7ff66921c8 "nir.h", line=2536, function=0x7ff6692630 <__PRETTY_FUNCTION__.13> "nir_instr_as_intrinsic") at assert.c:101 #6 in nir_instr_as_intrinsic (parent=0x7fd4b648e8) at nir.h:2536 #7 in coord_offset (ssa=0x7fd4b649d0) at ir3_nir_lower_tex_prefetch.c:77 #8 in coord_offset (ssa=0x7fd4b64a90) at ir3_nir_lower_tex_prefetch.c:48 #9 in ir3_nir_coord_offset (ssa=0x7fd4b64a90) at ir3_nir_lower_tex_prefetch.c:104 #10 in lower_tex_prefetch_block (block=0x7fd482c100) at ir3_nir_lower_tex_prefetch.c:185 #11 in lower_tex_prefetch_func (impl=0x7fd4aa0890) at ir3_nir_lower_tex_prefetch.c:218 #12 in ir3_nir_lower_tex_prefetch (shader=0x7fd4942b10) at ir3_nir_lower_tex_prefetch.c:242 Cc: mesa-stable Signed-off-by: Danylo Piliaiev <dpiliaiev@igalia.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/25096> |

`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.
