asmslicer
asmslicer is the LOCI static-analysis service. It slices ELF binaries (embedded firmware and executables) into:
- ASM basic blocks and linear execution segments, including CFG info.
- Callgraph between functions.
- Symbol and variable-access information.
and additionally provides binary diffing, worst-case stack-depth estimation, ROM/RAM memory-usage reports, and cross-artifact symbol dependency resolution.
Documentation
Full documentation lives in docs/ — start with the overview.
| 1. Overview and scope | What the service does; scope boundary vs. the TDMP trace pipeline |
| 2. Architecture | Processing pipeline, disassembly engines, data flow |
| 3. CLI reference | Subcommands slice, diff, stack-depth, memmap, deps; exit codes |
| 4. Output formats | Normative schemas of all CSV/DOT/JSON artifacts |
| 5. Analyses | Methods, assumptions, guarantees, blind spots |
| 6. Platform support | aarch64 / Cortex-M / TriCore support matrix |
| 7. Deployment and operations | Docker image, env vars, security posture |
| 8. Dependencies | Third-party inventory and licenses |
| 9. Quality assurance | Test suites and golden-data regression evidence |
| 10. Limitations and determinism | Soundness limits, reproducibility statement |
| 11. Release and versioning | CI/CD, image tagging, provenance |
How do I get set up?
- asmslicer uses uv for Python project and dependency management; install uv first.
External dependencies
The following system tools are required for full functionality:
binutils— providesc++filtfor C++ symbol demanglingllvm-18— providesllvm-ifs-18for interface stub generationrustfilt— for Rust symbol demangling
On Debian/Ubuntu:
sudo apt-get update && sudo apt-get install binutils rustfilt
wget -qO- https://apt.llvm.org/llvm.sh | sudo bash -s -- 18
For CUDA binary analysis (optional):
# Requires NVIDIA CUDA toolkit
sudo apt-get install cuda-cuxxfilt-13-0 cuda-cuobjdump-13-0 cuda-nvdisasm-13-0
- Then configure the venv using uv:
uv venv
source .venv/bin/activate
uv sync
- Once the venv is set up you can run the service CLI locally:
loci-service-asmslicer --help
loci-service-asmslicer slice path/to/app.elf ./out
- The Docker container image can also be built in the standard way:
docker build -t loci-platform/loci-service-static-analysis .
Contribution guidelines
- The project uses the
mainbranch for active development. - Changes are merged by creating a pull request targeting
main. - Merging to
mainautomatically triggers a build pipeline which deploys the Docker container to AWS ECR with thelatesttag. - Creating an annotated tag with an
x.y.zversion number triggers a pipeline build which deploys the Docker container to AWS ECR with thex.y.ztag. See docs/11-versioning.md.
Who do I talk to?
- Repo owner or admin.
