Some of the software I've written
- libgccjit: a branch of GCC allowing it to be built as a shared library for use in Just-In-Time compilation
- gcc-python-plugin: allowing you to write new GCC plugins in Python.
- cpychecker: a static analysis pass for GCC to find bugs in C extensions to Python, written in Python using gcc-python-plugin
- gdb Python hooks for debugging CPython itself
- gdb-heap, an extension to gdb for analyzing malloc/free
- squeal: a SQL-like syntax for use in shell pipelines
- asmdiff: tool for comparing objdump results
- gccinvocation: Python module for parsing GCC invocation lines
- jamais-vu: a tool for working with DejaGnu output
- firehose: a proposed common format for static analyzer output, along with a Python module for working with it
- mock-with-analysis: a way of rebuilding an RPM in mock, injecting static analysis, and capturing the result in Firehose format
- gcc-build: some scripts to make it easier to hack on GCC
I'm currently working on GCC upstream. Previously I worked on the Python runtimes within Fedora and Red Hat Enterprise Linux.
I'm interested in static code analysis
