Solved bug found by Teme about asserts.
Previously assert expression containing -> would lead to unnormalized ite. Now each expression within the assert is normalized and may bind new node equations.This could be later optimized but is working now.
- corrected a bug in optimizating mode (option -O 3) - changed the printing of unused variables
- corrected bug in node reset clock - cleaner (but heavier !) code generation scheme for automata
- Added major feature: Lustre V6 automata !!! - one automata example added - changed the reset condition in node calls (now a simple bool expr) - bug corrected in clock calculus - bug corrected in traceability info - added field in variables to test whether they are original...
- work in progress for automata...
This is a major revision: - added interface files (.lusi) in the language, that can be compiled on their own, giving an object file (.lusic) and a header file (.h) - modular code generation, from Lustre to C level included. - nice amount of code refactoring
- started refactoring type definitions in .lus/.lusi, in order to ease the way .lusi interface files are handled.
- added missing constraint check when sub-clocking tuple expressions - added an algorithm that reuses dead or clock-disjoint variables instead of declaring/using new ones. - NOT carefully tested. Use option -O 3 if you want to give it a try...
Updated the licence info and header for each file.Moved backends in separate folders
- many bugs/limitations in lifting operators to tuples have been worked out: - typing/clock calculus/normalization now work properly - still, a bug in annot generation (this one is for Ploc !!) in file normalization, line 396 - bug corrected in subtyping...
Merged horn_traces branch
Prepared first stage of code reorg:1. moved type def in lustrespec.ml2. moved constructor and basic functions in corelang3. Modified eexpr with prenext quantifiers
Added the lustre backendStill some work on adapating the instruction scheduling
- corrected causality bug (cf. previous commit)
improved code generation by factorizing out arrows
- work in progress for stateless/stateful status computation (to turn conditionals into merges, which yield more efficient C code)
Merge (if it works) of the lustre interfaces branche providing lusi files into trunk
Moved files to trunk in lustre_compiler
