This is a fork of the 'cil' package used for 'goblint'. Major changes include:
- Support for C99 and C11.
- Compatibility with modern OCaml versions.
- Use Zarith instead of Num and use that for integer constants.
- Improved locations with columns and spans.
- Removal of unmaintained extensions and MSVC support.
- Use dune instead of make and ocamlbuild.
- Many bug fixes.

C Intermediate Language (CIL)
CIL is a front-end for the C programming language that facilitates program analysis and transformation. CIL will parse and typecheck a program, and compile it into a simplified subset of C.
goblint-cil is a fork of CIL that supports C99, C11 as well as most of the extensions of the GNU C. It makes many changes to the original CIL in an effort to modernize it and keep up with the latest versions of the C language. Here is an incomplete list of some of the ways
goblint-cil improves upon CIL:
Support for C99 and C11.
Compatibility with modern OCaml versions.
Use Zarith instead of Num and use that for integer constants.
Improved locations with columns and spans.
Removal of unmaintained extensions and MSVC support.
Use dune instead of make and ocamlbuild.
Many bug fixes.
Install the latest release of
goblint-cil with opam:
opam install goblint-cil
ATTENTION: Don't install the
cil package. This is the unmaintained original version of CIL.
Installation from Source
First create a local opam switch and install all dependencies:
opam switch create .
Then, you can use dune to build
goblint-cil. Run the following commands to build and test
dune build dune runtest # runs the regression test suite
To run a single test go to the build directory (e.g.
_build/default/test) and run e.g.:
dune exec -- make test/array1
You can also install
goblint-cil into the opam switch:
dune build @install dune install
You can use cilly (installed in the opam switch) as a drop-in replacement for
gcc to compile and link your programs.
You can also use
goblint-cil as a library to write your own programs. For instance in the OCaml toplevel using Findlib:
$ ocaml OCaml version 4.14.0 # #use "topfind";; [...] # #require "goblint-cil";; [...] # GoblintCil.cilVersion;; - : string = "2.0.3"
