I know they fail, but I'll fix that latter.

Also disable tests that involves ecxexe with files that contain 'merge'.
indeed the -ec backend is not the priority.

nb: bad timings is due to NFS and pavé that is dying.

to behave as scanf("%d")

(the function that perform this job is actually in rdbg-plugin so that it is shared
with lutin and rdbg)

is the clock of the quicker clock among its inputs, not among its output !

soc2c: fix the code generated for array concatenation (which was raising a warning and a Seg fault).

Indeed, for big integers, looking at |x-x'|<eps leads to false
positive, because of the precision (*); it is better to to look at
|1-x/x'|<eps

(*) the precision (-p 6) influence the comparison, because the SUT
currently sends its result via a socket and truncate the result
(which is probably a bad idea).

nb : the exec time explose (x3), but for an external (unknown) reason
(undoing the change leads to the same exec time ~800s).

nb : the -exec mode was working because I did not use the generated soc,
which was completely wrong.

Note that to do that, I have modified the CURRENT variant of
Lic.val_exp, to attach it the clock the current holds on. Indeed, the
clock is mandatory to generated correct code...

In an ideal world, this clock information may have explicitely been
set by the user ("current(clk_of_X,X)" instead of "current(X)"), but
for historical reason, it is not the case.

Hence, this information is added as soon as it is available, namely,
during clock checking.

Indeed, once the activation condition has been true, and when it is
false it wax returning the default value instead of the previous one.

# of expected passes 		1512 -> 1519
# of unexpected failures	84 -> 78

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

# 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.

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

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.

nb:  unexpected failures 127 -> 125

nb:  unexpected failures	144->143

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: 20 more tests passes.

Always use Soc2cPredef.gen_assign to generate var assignments.

Also, use affection for assigning structures.

nb: 21 more tests passes.

Also do not crash if the soc contains reference to extern types.

It generates C code that compile on at least one example.

Add the modes3x2 exemple of Pascal (its version + a la V6 version).

Fix the doc wrt the merge exemple (the tex was refering to a
non-existant file).

cf git sha 55d3d77c470f416befd16a1b7d47f751eb2171fc of rdbg

More precisely, it was always returning the default value when the
activation condition was false instead of returning "dft_val fby out".

A few Array.copy were necessary when updating the memory.

Actually, it was a misunderstanding of mine (R1) ; the behavior was consistent
with the lv6 doc, but not with the v4 behavior...

Indeed, # means "at most 1 among n", not "exactly one among n" as I tought...

nb: test run on trieves, not triglav that is down, so the time is meaningless

Also, check programs that should fail using lurette instead of just
lus2lic. Indeed, some programs are only suposed to fail at runtime.

Change the main node names of prog in should_fail as it is necessary
for Lurette non-reg scheme

By redirecting the stderr of ecexe onto stdout, ecexe now terminate properly when called from lurette.

Hence, I have no more unresolved test (they are now failures) and the exec
time is now 98s (versus 217!!)

Some failures were actually due to wrong programs (mved to should_fail/semantics)

nb : the change has actually been done in lurette.

when the arity of an alias node was wrong.

  #fail: 83 -> 81

itself calls another node on a non-trivial clock (i.e., using a when)
was not producing correct code.

I've fixed this by performing the fix-point on nodes rather than on
equations. Indeed its more natural and efficient, and it avoid the
problem above. However, I did not really fix the problem, but just
turn around it. All tests seems to work fine though.

nb : #FAILS=81->80 (and -2 unresolved, but because I fixed the prog)
