This is apparently due to a missing source file, "utils.ml", but
unfortunately I have no idea what has happened to it (I'm not the
original author). Luckily it only seems to be used for a single
function definition (find_with_result), so we can just re-implement
that.
Another thing which might bite you is that recent OCaml versions don't
like hyphens in filenames: replacing them with underscores works OK
though (i.e. neon_schedgen.ml).
Compiling neon-schedgen.ml with the attached patch, the parts of
cortex-a8-neon.md below the line:
;; The remainder of this file is auto-generated by neon-schedgen.
are generated identically.
Would you like to try this out and see how you get on with it?
Followups set to gcc-patches.
Thanks,
Julian
