To avoid cyclic module dependencies (that show up when trying to
compile, e.g, the generated C code), enumerated types declared in the
main program are now "moved" into the module containing the generated
controllers.
To enable recovery of parameter and output ordering by `ctrl2ept', the
Controllable-Nbac generation procedure now declares a new module
dedicated to the encapsulation of the controller functions yet to be
synthesized.
Handling of type declarations are probably buggy.
Allowing additional inputs from abstractions within contracts. Thus,
calling non-inlined subnodes is allowed, as well as operations on
non-Boolean inputs or states (in contracts).
- Stripped portions of `myocamlbuild{,_config}.ml' that seem useless
when `-use-ocamlfind' is passed to ocamlbuild.
- Added some code in `myocamlbuild_config.ml' to be able to generate
documentation by merging interface and implementation files.
- CtrlNbac: new module for internal representation and output code for
Controllable-Nbac format;
- CtrlNbacGen: translation into Controllable-Nbac of Minils nodes
necessitating controller synthesis; the insertion of calls to
controllers is not yet done, and the nodes are left unchanged.
- 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
- 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).
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).
- 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)
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.
