A "newbies" guide to hacking on GCC (and plugins)

I'm a relative newcomer to GCC [1], so I thought it would be a good idea to try to capture some of the "gotchas" and similar information on hacking on GCC in the form of a short guide for new contributors, whilst the experience of learning it is still fresh in my mind. The guide can be read here:

The following patch implements a new function-body-elision optimization, which can dramatically improve performance, especially under certain benchmarks. For example, given this test program... $ cat test.c int factorial (int i) { if (i > 1) return i * factorial (i - 1); else return

New GCC plugin: gcc-python-plugin

I've been working on a new plugin for GCC, which supports embedding Python within GCC, exposing GCC's internal data structures as Python objects and classes. The plugin links against libpython, and (I hope) allows you to invoke arbitrary Python scripts from inside a compile. My aim is to allow pe

A visualization of GCC's passes, as a subway map

For fun over the weekend I wrote a python script (using my gcc-python-plugin[1]) to render an SVG diagram of GCC's optimization passes (or, at least, based on my understanding of them). This diagram shows the various GCC optimization passes, arranged vertically, showing child passes via indentatio

gcc-python-plugin status update: static analysis, and HTML reports

I've written up a status update on the gcc-python-plugin on my blog here: http://dmalcolm.livejournal.com/6560.html Summarizing that blog post, I've revamped the internals of how my checker script so that it can detect various kinds of CPython reference count bug, and it can now render bug reports

gcc-python-plugin is a plugin for GCC 4.6 onwards which embeds the CPython interpreter within GCC, allowing you to write new compiler warnings in Python, generate code visualizations, etc. Tarball releases are available at: https://fedorahosted.org/releases/g/c/gcc-python-plugin/ Prebuilt-docum

gcc-python-plugin finds its first bug in itself

gcc-python-plugin [1] now provides a gcc-with-cpychecker harness that runs gcc with an additional pass that checks CPython API calls (internally, it's using the gcc python plugin to run a python script that does the work). I tried rebuilding the plugin using make CC=../other-build/gcc-with-cpych

Working with frontend-specific aspects of GCC from a GCC plugin

I maintain gcc-python-plugin [1]. I'm hoping to expose the function decl_as_string() from the C++ frontend from within my plugin. Unfortunately, given that that symbol is defined within gcc/cp/error.c, it is only defined within the C++ frontend: cc1plus. This works OK when my plugin is dynamical
