I'm currently working on GCC upstream.  Previously I worked on the [[SIGs/Python|Python runtimes within Fedora]] and Red Hat Enterprise Linux.

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

GCC work

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
