GSoC

[David Malcolm]

Hi Isitha (and Philip!)

If I'm reading Isitha's email correctly, it talks about static
analysis, whereas Philip's talks about GCC Rust, so some wires got
crossed somewhere.

I'm the author of the GCC static analysis pass.  I should confess that
I still feel like I'm learning static analysis myself - I too own a
copy of the Nielson, Nielson & Hankin book you mention, but have only
skimmed it.  FWIW, I find the very early papers by Patrick and Radhia
Cousot from the beginning of the field much easier to read, as they
take more time spelling out the meaning of the mathematics.  I should
also confess that the analysis pass takes some liberties compared to a
formal approach, grabbing ideas from here and there, plugging them into
30+-year-old codebase in a way that I hope is a reasonable trade-off
between speed, (lack of) soundness, (lack of) completeness, and
readability of output by end-user.

The static analysis pass is meant to be reasonably modular, so the
various suggested projects listed on the wiki page ought to be
implementable without knowing everything all at once.

However, as Philip says, GSoC imposes a particular timeline, and I
don't know to what extent might be a dealbreaker.

Hope this is helpful
Dave
