- corrected bug in node reset clock
- cleaner (but heavier !) code generation scheme for automata
6a1a01d2 09/14/2014 08:08 PM Xavier Thirioux

- 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
6aeb3388 07/15/2014 09:27 AM Xavier Thirioux

- started refactoring type definitions in .lus/.lusi,
in order to ease the way .lusi interface files are handled.

- corrected a small bug in clock calculus

- several bugs corrected when mixing tuples with clocks
01f1a1f4 07/10/2014 12:49 PM Xavier Thirioux

- 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
2cf39a8e 07/08/2014 04:53 PM Xavier Thirioux

- 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...

Prepared first stage of code reorg:
1. moved type def in lustrespec.ml
2. moved constructor and basic functions in corelang
3. Modified eexpr with prenext quantifiers

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...

- refactorization of typing code (simpler subtyping rules)
- simplification of clock calculus (may be still buggy, work in progress)
no impact on unclocked programs.

bug correction in homomorphic extension
84d9893e 03/24/2014 09:05 AM Xavier Thirioux

- corrected causality bug (cf. previous commit)
d3e4c22f 03/14/2014 05:45 PM Xavier Thirioux

- work in progress for stateless/stateful status computation
(to turn conditionals into merges, which yield more efficient C code)
2ea1e4a6 03/13/2014 05:30 PM Xavier Thirioux

corrected bugs in clock generalization that produced pessimistic C code (not wrong though); corrected bug with node importation policy wrt (re)declaration, (re)definition...
c518d082 03/01/2014 03:37 PM Xavier Thirioux

- added generation of clock information in interface (.lusi) files
- added clock checking between interface and implementation files
8b3afe43 02/28/2014 04:56 PM Xavier Thirioux

- merged test script
- added -d support
- corrected #open parser problem
- corrected interface/implementation (.lusi/.lus) checking
for types (not yet for clocks)

Merge (if it works) of the lustre interfaces branche providing lusi files into trunk
0cbf0839 10/02/2013 08:13 AM Pierre-Loïc Garoche

Moved files to trunk in lustre_compiler
