Essential Abstractions in GCC

A tutorial conducted in conjuction with CGO 2011, Chamonix, France


Target Audience

People interested in using GCC for their research as well as people interested in contributing to GCC will benefit from this tutorial. It is expected that this tutorial will bring down their ramp up period into GCC from several frustrating months to a few stimulating weeks. This tutorial will also be useful for people who are interested in relating class room concepts of compilation to a large scale practical compiler which is widely used.

Special Requirements

This tutorial is a lecture based tutorial and hence it is not necessary for the audience to bring a laptop. Soft copies of the slides will be made available on this page well in advance.
