Dear Friends, I have submitted a tutorial proposal for GCC Summit. This email to get an idea of whether this tutorial will be of interest to a sufficient number of people. We have been conducting expanded versions of this tutorial in India for past few years and it seems to generate some interest. Some friends in US suggested that we should hold some version outside of India hence I have sent in a proposal to GCC Summit.
Looking forward to getting some feedback. I would also be happy to modify the tutorial based on the feedback. Thanks and regards, Uday. ---------------------------------------------------------------------- Dr. Uday Khedker Professor Department of Computer Science & Engg.

As a consequence, a clear and crisp explanation of the journey from a given machine description to an actual run of a compiler generated from that machine description is not available. In this tutorial we describe some carefully chosen abstractions that help one to understand the retargetability mechanism and the architecture of the compiler generation framework of GCC and relate it to a generated compiler. Coverage -------- The default duration of this tutorial is one day and it covers the following topics: Meeting the challenge of understanding GCC. The architecture of GCC. Basic concepts in GCC configuration and building. The structure of a GCC generated compiler. Plugins structure of GCC. First level graybox probing of the compilation sequence of a GCC generated compiler. Graybox probing for machine independent optimizations. Graybox probing for parallelization and vectorization. Adding Gimple and RTL passes to GCC. The retargetability and instruction selection mechanism of GCC. Designing and understanding GCC machine descriptions. The abstractions in GCC machine descriptions and their influence on a compiler generated from them. The design and implementation of gdfa (generic data flow analyzer) for GCC. We have held several tutorials and workshops along these lines in past few years in India and now would like to reach out to a larger audience. Our main source of material is the Workshop on Essential Abstractions in GCC held at IIT Bombay from 5th July to 8th July 2010 (http://www.cse.iitb.ac.in/grc/gcc-workshop-10). Target Audience --------------- People interested in using GCC for their research as well as people interested in contributing to GCC will benefit a lot from this tutorial. It is expected that this tutorial will bring down the ramp up period of novices to 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. ---------------------------------------------------------------------- Dr. Uday Khedker Professor Department of Computer Science & Engg.
