Gwenal Delaval cf22ba3989 Optional block in contracts 
Optional let...tel block in contracts
Sink state in sigali
 2012-06-07 17:48:31 +02:00
Gwenal Delaval 2bd31db883 Causality and scheduling with contracts 
Correction of the causality analysis and scheduling (with interference)
to take contracts into account.

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).

Gwenal Delaval 1e46c2a73c Makefile : removed target "all" from target "install" 
On some systems, the targets "all" and "install" must be
made with different rights. Then "all" cannot be a dependendy of
"install", especially since ocamlbuild try to read/modify some
files even if there is no compilation to perform.

Gwenal Delaval bb0bc8bfe5 Added local assume/guarantee 
Added local assume/guarantee in contracts.

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

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 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.

Cédric Pasteur f66c9045df Special case for merge in the scheduling 
For merge equations, the generated code will be 
on a different rate than the activation clock of
the equation.

belongs.

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.

Cédric Pasteur 06e997e0c8 Fix for -mall 
Do not share memories and outputs if they are not
arrays, as it might make the register allocation
by the C compiler less efficient.

Cédric Pasteur b1bd6dbd57 Compare clock repr 
Not sure this is necessary but it doesn't hurt to
