Basic library printers moved into backend specific printer files
8446bf03 03/30/2018 05:54 PM Pierre-Loïc Garoche

- Makefile: solved dependency problem when compiling include lusi
- Renamed type declarations as lustre_types and machine_code_types
3c3414c5 02/01/2018 02:42 PM Pierre-Loïc Garoche

Solved issue with typing of enumerated types
66359a5e 01/31/2018 07:27 AM Pierre-Loïc Garoche

[general] large modification: added machine types, a second typing phase dealing with machine types (eg uint8)
typing was transformed as a functor and parametrized by basic types (int/real/bool)
it can also be applied multiple times on the same program
333e3a25 12/18/2017 09:57 AM Pierre-Loïc Garoche

[general] Refactor get_node_eqs to produce (eqs, auts) with automatons
85da3a4b 04/26/2017 11:23 PM Pierre-Loïc Garoche

Merge branch 'unstable' into merging_plugins
Non regression results were similar to master branch

bug correction in typing: tuple types were computed but not recorded

Major revision due to severe limitations and bugs of inlining capabilities:
- destination dir should now work properly
- lusic files now have a version number, to avoid nasty segfaults
when loading lusic files created by an older compiler version
- inlining should now work with generic nodes and generic array library...

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...

correction of bugs:
- a small problem in the parser
- regarding the handling of destination directory, source directory, current directory, etc.
It seems to be working now. A nice chasing after weird behaviors...

- 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...

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...
