Cédric Pasteur a00620ca19 Fixed interference of fast memories 
A fast memory should be considered alive during
the whole step function when its clock is false.

Cédric Pasteur 99dc7820c7 Avoid crash in memalloc 
Check if both variables are optmized
 2013-04-22 18:11:10 +02:00
Nicolas Berthier 8497bafa2e Minor but correction in sigali output. 
- Translation to z3z now evaluates constant expressions instead of
  abstracting them. This non-feature could cause "false" synthesis
  failures due to non-translatable yet constant expressions possibly
  introduced by tomato (or manually), for instance `not false' in node
  `n' bellow:

    node n (a: bool) returns (ok: bool)
      contract assume true enforce ok with ()
    let
      ok = a or not false;
    tel
 2013-04-11 17:30:30 +02:00
Nicolas Berthier 9db97de879 Bug correction in `Sigalimain.translate_eq'. 
- In Sigalimain: untranslatable non-boolean expressions should not be
  added as inputs of the controller.

- Avoided some compiler warnings in the same module (with OCaml ≥ 4).

Gwenaël Delaval f60b00e9e3 Bug correction in Inline_extvalues 
Added handling of controllable variables in Inline_extvalues
 2013-02-08 14:42:26 +01:00
Gwenal Delaval 2be4e287b9 Take into account the -nosink option in Sigali 
Corrected bug: do not suppress the last state
variable when -nosink is on.

Gwenaël Delaval 5a9b27d6a9 Correct handling of local assume/enforce of contracts 2012-12-11 08:20:04 +01:00
Gwenal Delaval ce2e2bdcd0 Added -nbvars option for performance evaluation 2012-11-26 10:05:20 +01:00
Gwenaël Delaval ef536f412d Added option -nosink (CS optimisation) 
The -nosink option suppress the sink state of sigali equations.

This optimizes the controller synthesis, but work only
when the synthesis objective instantaneoulsy depends only
on the current state (and not on current inputs).

Gwenal Delaval 41fccc66fb Bugs corrections 
- callgraph: add idents used for instantiated nodes
- cgen : added Idents.enter_node
- cmain : removed error when simulated node does not exist (existence
of simulated node was tested for every program, comprising loaded ones)

Gwenaël Delaval 72b1bd8de3 Typo in error message 2012-07-26 01:33:32 +02:00
Gwenaël Delaval 90dda27a3a Bug correction in Schedule_interf 
Bug due to the fact that a variable can be "defined" and "read"
(in scheduling sense) by the same equation, without being a memory:
e.g., a clock defined as the result of a node application, together
with another result on this same clock.

Bug correction: basically removed the "assert false" on killed_vars,
decr_uses; do not count as "use" the self reads.
 2012-07-26 01:29:22 +02:00

Cédric Pasteur 8815a2cd03 Better handling of clocks in memalloc 
- We can do a better allocation if we take into
account 'when' in extvalues 
(test/good/memalloc_clocks.ept shows the
improvement)
- Fixed a bug with memalloc on records: if we 
translate:
o = { a with .f = u }
to
o = a; o.f = u
then we cannot share u and o.f

Gwenal Delaval 2bd31db883 Causality and scheduling with contracts 
Correction of the causality analysis and scheduling (with interference)
to take contracts into account.
 2012-06-07 15:27:07 +02:00
Gwenal Delaval 2956002f85 Correction and simplification of the sigali pass 
Added a "Contracts" pass, after inlining, taking care of the
contracts of the nodes called in the body of a node. This pass
"inlines" the code and assume/guarantee parts of these subcontracts.

The "Sigali" pass both generates the sigali ("z3z") code and add the call to
the controller (which is a node generated further by the sigali tool).
Therefore this pass has been included into the mls compiler, and removed
from the targets (a "z3z" dummy target has been kept for backward compatibility
reasons).
 2012-06-06 15:59:08 +02:00
Gwenal Delaval bb0bc8bfe5 Added local assume/guarantee 
Added local assume/guarantee in contracts.

No syntax associated to these local asume/guarantee: internal use only.

Cédric Pasteur 6e2e2a9f47 Fixed bug in interference computation 
To know the variables read by an equation, we should
only look at the clock of variables. Otherwise, 
there could be a problem for node calls that 
define new clocks.

the equation.

Cédric Pasteur 06e997e0c8 Fix for -mall

Cédric Pasteur 70787757aa Fixed normalization of fby 
The incorrect behaviour was introduced in commit
6b86b86e9d.

We should have:
       o = v fby e
     becomes
       mem_o = v fby e;
       o = mem_o

The old way would break with:
 v = true fby false fby v
that would generate unschedulable code.
 2011-09-08 11:45:43 +02:00
Cédric Pasteur 81947eca40 Made linearity field not optional 
This helped solve a few bugs with linear types,
for instance when using automata.
The intermediate code is not well-typed (wrt to
linear types only), after the encoding of automata.

 2011-09-07 14:14:59 +02:00
Cédric Pasteur 7ac567cc35 Update the signature instead of recreating it 
This avoids losing additional info in the
signature (such as linearity)
 2011-09-07 11:32:16 +02:00
