For instance, do not launch tests that perform result comparison (via
lurette) on files that contains extern nodes (as they cannot be
executed) or package.  Package do not work because appending the
tested lustre file with the generated oracle as I do is wrong in
presence of package.

Moreover, my current test process is not able to test programs which
main node IOs are not all on the base clock. I have fixed this by
patching the examples.

# of expected passes 		1508 -> 1512
# of unexpected failures	130 -> 84

30 tests fail, but 169 pass!!!

# of expected passes 		1339 -> 1508
# of unexpected failures	100 -> 130

and -2c).  Indeed, the l2lExpandArrays sometime transforms a
Lic.var_exp ve into TUPLE[ve].

# of unexpected failures	101->109

but actually, some new test passes causes several other failing test
to be tried, so it is not really a regression.

Indeed, ite are polymorphic, and thus inventing names during soc
instanciation is error-prone, ugly, innefficient, and increase the
code size.

Moreover, using C ite to translate them online (ie, without going
trough a soc) is straigforward

In other words, consider ">" and co as overloaded operators, not polymorphic ones.

where I've removed the handling of polymorphism.

where I've removed the handling of polymorphism.

e.g., by replacing "plus" by "iplus" or "rplus"

Hence now the following is accepted :
   res = map<<+,  N>>(x, a, b);

but still not

  a_or_b = map<<Lustre::if,  N>>(x, a, b);

For instance,
  node toto = map<<Lustre::if,  N>>(x, a, b);
is rejected.

The problem with this change is that we now also reject equations such as
   res = map<<+,  N>>(x, a, b);

which could be avoided. Probably L2lRmPoly does its job partially.

I've sligthly modified the profile of gen_assign to explicitly ask for the
size of the data structure to be copied.

The arrow soc now has a memory used to hold if the first step has be triggered.

The first one in Soc2cIdent.type_to_short_string when enum and int were both
translated by "i" ; as a consequence, some different soc ctx get the same name.

The second one was due to the fact that car ident in gao switches were
printed incorrectly (missing "ctx->" or "node_no_mem_ctx.").

nb:  unexpected failures 162-> 149

nb:  unexpected failures 175-> 162

Also name step function consistent and uniquely

nb:  unexpected failures 187->175

nb:  unexpected failures 195->187

Also start to add support for the other iterators, but it does not work yet.

The idea is that
- when it is not in the memory, it is considered as true
- it is set to false after each step is executed
