Subject: [Bug 1477363] Review Request: ocaml-cmdliner -
Declarative definition of command line interfaces
for OCaml

I believe you can change the ocamlbuild command line to add

ocamlbuild ... -tag debug

(https://nicolaspouillard.fr/ocamlbuild/ocamlbuild-user-guide.html)

You'll also want to check what actual ocamlopt commands are being
executed to ensure that -g is passed to them all.

To check that debuginfo is being generated at all, look at the
*.o files. For example:

echo 'print_endline "hello world"' > test.ml
ocamlopt.opt -g test.ml
eu-readelf --debug-dump=info test.o

You should see entries such as ‘name’, ‘comp_dir’.

However if -g has been omitted then eu-readelf will give an error:

eu-readelf: cannot get debug context descriptor: No DWARF information found

You can also run the same commands on executables.
