LOTS of bug correction wrt inlining, still a work in progress...
- global constants were not accounted for
- no good avoidance of name capture when inlining
- static parameters (array sizes and clocks) not handled
- ill-typed generated expressions, when inlining array expressions

Changed the option horntraces to a general traces option
This annotation phases would have to be moved in optimization of normalized code

e9c64a30 03/05/2015 11:48 PM Pierre-Loïc Garoche

Reactivated the generation of traceability information
Changed the test-compile to use the horn-traces and the horn-queries option

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

d5fe9ac9 09/18/2014 05:25 PM Xavier Thirioux

- 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...

1eda3e78 09/09/2014 06:03 PM Xavier Thirioux

- 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.

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...

36454535 07/03/2014 10:46 PM Pierre-Loïc Garoche

Merged horn_traces branch

0038002e 07/02/2014 05:29 PM Pierre-Loïc Garoche

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

49ddf66d 06/25/2014 10:54 AM Pierre-Loïc Garoche

Added the lustre backend
Still some work on adapating the instruction scheduling

84d9893e 03/24/2014 09:05 AM Xavier Thirioux

- corrected causality bug (cf. previous commit)

14ebde97 03/17/2014 01:01 PM Xavier Thirioux

improved code generation by factorizing out arrows

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)

f22632aa 10/22/2013 10:39 AM Pierre-Loïc Garoche

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
