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 9334b73ef1 Naive abstraction for sigali 2012-08-08 18:16:33 +02:00
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 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.

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.

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 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.

Cédric Pasteur f66c9045df Special case for merge in the scheduling

on a different rate than the activation clock of
the equation.

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.
