generates unvalid C code.

The bug was appearing a node was called on a non base clock that was
existing in the called nodes (name clash). Typically, it occurs on
recursive node called on some non-trivial clocks.

Also, use maps instead of list to hold the substitution between
params and args.

More precisely, I missed clock in the ve_clk field of val_exp.

and replace enumerated clock in the var_info even if it does not
appear in a val_exp.

nb : luciole-rif is now  in the rdbg repo.

var_info appears in
- node decl
- left var
- static args

not yet working. I commit as Ive fix a missing dep on WenOnId in the _oasis.

More precisely, transforms equations of the form

   y = x when Toto(c);

into

   x when Toto_c ;
   Toto_c=Toto(c);

Rationale: the << normal mode >> (i.e., not translating enums) was
not even accessible!

('::' vs '__')

soc2c -2cw7: use mkff+fixffx+arm.looploc to fix extern lib calls.

The bug was (in soc2c.ml::137) that, for array of instances of size
n, it was generating n+1 initialisations, causing a seg fault.

Factorize duplicated code in gen_loop_file and gen_loop_file4ogensim
along the way.

by
- remove duplication (add a profile_info function ine Lv6Verbose
- be more efficient (computing Sys.time only when necessary
- control the time-profiling printing via the -dbg flag "profile", and
  not the verbosity level

I was re-implementing an inneficient topological sort there (using a
linear list instead of logarithmic map). I win 1s on tri.ec (~8000
locals).

I did a map instead of a fold when checking for the absence of cycle.
On programs with 10 000 of equations, I go from 150s to 5s.

Also, force a workflow (via a lock file named commited) that make
sure that the content of lv6version.ml is always correct xrt shat and
git commit number.

as an opam package in the verimag opam repo.
