Subject: [PATCH] Add BINSEC.
Date: Sat,  3 Feb 2024 16:03:19 +0100

From: Sören Tempel <soeren <at> soeren-tempel.net>

This patchset adds a package for BINSEC <https://binsec.github.io/>.
BINSEC is a popular tool for binary program analysis using symbolic
execution.  Symbolic execution is a technique for automated software
testing and an active area of computer science research.  This package
for BINSEC is part of and ongoing effort to package symbolic execution
tools in Guix, thereby easing the creation of computational environments
for reproducible research in the symbolic execution domain.

BINSEC requires 9 new OCaml packages, most of them originate in Dune.

Sören Tempel (10):
  gnu: Add ocaml-iso8601
  gnu: Add ocaml-toml.
  gnu: Add ocaml-pp.
  gnu: Add ocaml-grain-dypgen.
  gnu: Add ocaml-ordering.
  gnu: Add ocaml-dyn.
  gnu: Add ocaml-stdune.
  gnu: Add ocaml-dune-private-libs.
  gnu: Add ocaml-dune-site.
  gnu: Add binsec.

Thanks for the patch series! I have another series I need to push first
(which I should be able to do after FOSDEM):
https://issues.guix.gnu.org/64249. I recognise the dune packages from
this other patch series here. We'll drop them, sorry you had to do this
work for nothing.

I can't take a look right now, but I'm super excited to get binsec in
Guix!

Applied to master as 8b679328512fbf5ca4c50c446884fc6069fdb589 to
16d2be641424815a1779119bb64bc6ba1be1161b, with minor tweaks to the
description of a few packages, removed ocaml-findlib from inputs, since
it's already implicit, and added a copyright line for you. Thanks!

Thank you for merging this! Is there any chance you could also take a look at
my KLEE patch <https://issues.guix.gnu.org/68296>? Similar to BinSec, KLEE is
a very popular symbolic execution tool. Unfortunately, I couldn't find a
suitable team for this patch and hence it has been stale for a while.

Greetings
Sören
