nix: Pull CBMC 6.9.0 from nixos-unstable binary cache by mkannwischer · Pull Request #1666 · pq-code-package/mlkem-native

mkannwischer · 2026-04-25T03:03:51Z

CBMC 6.9.0 is now available in nixos-unstable, so we can fetch it prebuilt instead of rebuilding from source.

Also drop the standalone cadical binary from the CBMC package env, the CI version-summary line, and print_tool_versions.py: cbmc bundles its own cadical internally, so the standalone one on PATH did not reflect the solver actually used.

CBMC 6.9.0 is now available in nixos-unstable, so we can fetch it prebuilt instead of rebuilding from source. Also drop the standalone cadical binary from the CBMC package env, the CI version-summary line, and print_tool_versions.py: cbmc bundles its own cadical internally, so the standalone one on PATH did not reflect the solver actually used.
