Description Andrii Batyiev 2024-11-28 20:20:12 UTC 
While compiling media-libs/mesa, I got this message:
[186/1503] env MESA_SHADER_CACHE_DISABLE=true /usr/bin/intel_clc --llvm17-wa --nir --gfx-version=8 --prefix gfx8_intel_shaders --in ../mesa-24.2.6/src/intel/shaders/libintel_shaders.h --in ../mesa-24.2.6/src/intel/shaders/generate.cl --in ../mesa-24.2.6/src/intel/shaders/generate_draws.cl --in ../mesa-24.2.6/src/intel/shaders/generate_draws_iris.cl --in ../mesa-24.2.6/src/intel/shaders/memcpy.cl --in ../mesa-24.2.6/src/intel/shaders/query_copy.cl -o src/intel/shaders/intel_gfx8_shaders_code.h -- -cl-std=cl2.0 -D__OPENCL_VERSION__=200 -DGFX_VERx10=80 -I/var/tmp/portage/media-libs/mesa-24.2.6-r2/work/mesa-24.2.6/src/intel/shaders/. -I/var/tmp/portage/media-libs/mesa-24.2.6-r2/work/mesa-24.2.6/src -I/var/tmp/portage/media-libs/mesa-24.2.6-r2/work/mesa-24.2.6/src/intel -I/var/tmp/portage/media-libs/mesa-24.2.6-r2/work/mesa-24.2.6-abi_x86_x32.x32/src/intel -I/var/tmp/portage/media-libs/mesa-24.2.6-r2/work/mesa-24.2.6/src/intel/genxml
FAILED: src/intel/shaders/intel_gfx8_shaders_code.h 

In fact, it is intel_clc crash in blake3 code:

Program received signal SIGSEGV, Segmentation fault.

mesa & intel_clc now contain a copy of blake3 code inside and for x32 we already have blake3 crash described in #942562

I would argue that mesa should not bundle blake3 library, and it should probably be unbundled (and fix the related #942562).

Reproducible: Always

Comment 1 Matt Turner gentoo-dev 2025-04-15 16:37:02 UTC 
I believe this is fixed upstream by:

commit b9c6afd3a7c7ac302b47e70b5c745b84cb35f188
Author: Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>
Date:   Wed Apr 2 15:30:20 2025 +0300

    meson: disable SIMD blake optimisations on x32 host
    
    On X.org startup libgallium crashes on x32 hosts inside
    blake3_hash_many_sse41(), most likely because of the different pointer
    size. Disable SIMD blake implementation if x32 is detected.

Comment 3 Matt Turner gentoo-dev 2025-05-17 01:16:11 UTC 
Going to call this fixed. mesa_clc is fixed, and intel_clc is masked for removal.
