Gwenaël Delaval 5a9b27d6a9 Correct handling of local assume/enforce of contracts 2012-12-11 08:20:04 +01:00
Gwenaël Delaval 0e60d2e839 Boolean transformation: added inputs/outputs 
Non transformation of inputs/outputs during
Boolean pass lead to bugs.

Gwenal Delaval eddeb1f4de Bug correction tentative (itfusion) 
Tentative of correction of itfusion bug:

The itfusion pass adds some "anonymous" nodes into the module.

This correction adds the signature of these created nodes.

This only shifts the bug (towards clocking pass).

Gwenal Delaval ccab6f7aad Normalization of record consts 
Normalization of records as constant to ease the compilation:

Gwenaël Delaval 35bea85bf7 Boolean: no transformation on inputs/outputs 
Only translate local variables, so as to not
modify node interfaces.

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).

Added local assume/guarantee in contracts.

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

Adrien Guatto 070d2eab55 Revert "Changed linear typing for merge." 
This reverts commit 0abb050a23.
 2012-02-14 14:36:47 +01:00
Adrien Guatto 0abb050a23 Changed linear typing for merge. 
The new rule accepts that some branches of a linearly typed merge have linear
type Top, provided that at least one has type "lin". E.g.:

node f(x : int at r) returns (o : int at r)
var ck : bool;
let
  ck = true;
  o = merge ck (x whenot ck) 0;
tel

is now deemed valid.

Cédric Pasteur db5f55b221 Fixed when of stateful exp with memalloc 
As the expression inside the when will be called 
on a faster rhythm, we have to make sure not to
share it with a variable on the slow clock.
We do this by creating a new equation for the 
stateful exp.
