Validate voxtype binaries for CPU instruction contamination. Use when checking release binaries for AVX-512 or GFNI instruction leaks that would crash on older CPUs.
Verify that voxtype binaries don't contain forbidden CPU instructions that would cause crashes on older CPUs.
| Binary | Must NOT have | Must have |
|---|---|---|
| AVX2 | zmm registers, AVX-512 EVEX, GFNI | - |
| Vulkan | zmm registers, AVX-512 EVEX, GFNI | - |
| AVX-512 | - | zmm registers (confirms optimization) |

PASS conditions:
FAIL conditions:
If validation fails, the Docker build cache is likely stale. Recommend:
docker compose -f docker-compose.build.yml build --no-cache avx2 vulkan
