- started refactoring type definitions in .lus/.lusi, in order to ease the way .lusi interface files are handled.
- several bugs corrected when mixing tuples with clocks
- 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...
work in progress (code optimization again)
Merged horn_traces branch
added some infrastructure to ease optimization (reusing vars)
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
more steps toward reusing variables (dead ones + clock disjoint ones)
added construction of a fanin table for local variables of a node. could be useful for a finer variable elimination scheme at the Lustre level. to be continued...
added warnings for useless variables (at verbose level 1) - exact definition of 'useless' may be further refined - display could certainly be improved
Merged trunk updates
work in progress: - warnings for unused input/memory variables - optimization of machine code
Added the lustre backendStill some work on adapating the instruction scheduling
Restructured the main: call to optimization, scheduling performed out of machine_code, etcMerge Xavier last commitsUnfinished lustre backend
clean handling of undefined node application
Math lusi (trigo)
Solved bug:- loading lusi- loading lib in lusi files: "in m" is now "lib m"
Changed the load of lusi files: imported nodes or function can specify the linking lib and/or use a classical C prototype (without pointers).Parse updated as well as Makefile generation.
Added declaration/definition of stateless/stateful nodes. The 'function' keyword is for stateless nodes only, the 'node' keyword is any kind of node. Improves compilation and paves the way for more optimizations.
- work in progress for stateless/stateful status computation (to turn conditionals into merges, which yield more efficient C code)
corrected bugs in clock generalization that produced pessimistic C code (not wrong though); corrected bug with node importation policy wrt (re)declaration, (re)definition...
- added struct types declaration - added constant definition with a struct type - added checking for multiple definitions of nodes (behavior was buggy) - better and more uniform error messages for undefined/already defined symbols
We still need struct expressions...
more steps towards struct types...Cette ligne, et les suivantes ci-dessous, seront ignorées--

corrected bug in arrow macros names, added storage attribute for static alloc macros, option -d now creates the destination directory if needed, with current dir as file permissions
- added generation of clock information in interface (.lusi) files- added clock checking between interface and implementation files
Reenabled the generation of witnesses for inline process.Systematic use of the build path
- merged test script - added -d support - corrected #open parser problem - corrected interface/implementation (.lusi/.lus) checking for types (not yet for clocks)
Merge trunk modif in branch
Solved some bugs in the lustre printerGeneration of a witness with both the main node and hte inlined main nodeTest script modified to check consistency of the inlining process
First fully working version of horn backend.
Has to be called with "-horn -node main_node"
The test script compute the smt2 file and calls z3 on them.
Is it working?
Initial copy of the horn output version. Not really working yet
Merge (if it works) of the lustre interfaces branche providing lusi files into trunk
Moved files to trunk in lustre_compiler
