Control hazard analyzer

Control hazard analyzer (abbreviated cha.py) is toolchain for analyzing control hazards. Toolchain consists of three steps: test generation in C, test profiling using a profiler (perf, gem5 simulator), and result collection.

---

Requirements

• Python 3.10+
• gem5 (optional)

Installation

Clone the repository

git clone --recurse-submodules https://github.com/SE-Processor-Fuzzing/control-hazard-analyzer.git

gem5

For using gemProofiler one needs to have gem5 and library M5ops:

• gem5 installation
• M5ops installation

They can be installed manually or using thirdparty/gem5 submodule.

python3 ./scripts/install_gem5.py X86 opt ./thirdparty/gem5/build_cache

Tip

It is possible to configure ISA, build variant and build cache directory for gem5 installation. For more information run python ./scripts/install_gem5.py --help

cha.py dependencies

python3 -m pip install -r requirements.txt

Toolchain structure

• aggregate - toolchain driver
• generate - test generate
• analyze - execute and profile tests
• summarize - give statistics on analyzed files

aggregate

Usage example:

python3 cha.py aggregate

Example result:

Also, you can pass many options to utilities, see help for more details

generate

Usage example:

python3 cha.py generate --repeats=10 --out-dir="out" --log-level DEBUG

To read more about generate visit Docs

analyze

Usage example:

python3 cha.py analyze --test-dir="out" --out-dir="perf_result" --log-level DEBUG

To read more about analyze visit Docs

summarize

Usage example:

python3 cha.py summarize --src-dirs="perf_result" --out-dir="summarize_result" --log-level DEBUG

Multi-command Execution

You can pass multiple commands in a single run. This allows you to combine multiple steps into one command sequence

Usage example:

python3 cha.py generate --out-dir="tests" analyze --test-dir="tests" --out-dir="results" summarize --src-dirs="results" --out-dir="summarize_result"

Development

Requirements

python3 -m pip install -r requirements.dev.txt

Pre-commit

Install pre-commit-hooks

pre-commit install

Run manually

pre-commit run --all-files --color always --verbose
