- Renamed type declarations as lustre_types and machine_code_types

full merge of salsa/mpfr and master
ec433d69 04/08/2015 10:03 PM Xavier Thirioux

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...

- corrected bug in node reset clock
- cleaner (but heavier !) code generation scheme for automata

git-svn-id: https://cavale.enseeiht.fr/svn/lustrec/lustre_compiler/trunk@337 041b043f-8d7c-46b2-b46e-ef0dd855326e

- 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.

- corrected a small bug in clock calculus

- several bugs corrected when mixing tuples with clocks

git-svn-id: https://cavale.enseeiht.fr/svn/lustrec/lustre_compiler/trunk@316 041b043f-8d7c-46b2-b46e-ef0dd855326e

- 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

git-svn-id: https://cavale.enseeiht.fr/svn/lustrec/lustre_compiler/trunk@313 041b043f-8d7c-46b2-b46e-ef0dd855326e

- 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...
01c7d5e1 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

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.

- work in progress for stateless/stateful status computation
(to turn conditionals into merges, which yield more efficient C code)

89b9e25c 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...

- corrected #open parser problem
- corrected interface/implementation (.lusi/.lus) checking
for types (not yet for clocks)
