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...

34a5a072 07/07/2014 10:35 AM Xavier Thirioux

work in progress in liveness analysis...

7cd31331 07/04/2014 04:57 PM Xavier Thirioux

work in progress (code optimization again)

1837ce98 07/03/2014 10:40 PM Xavier Thirioux

added some infrastructure to ease optimization (reusing vars)

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

d96d54ac 06/27/2014 04:29 PM Xavier Thirioux

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...

9aaee7f9 06/26/2014 04:48 PM Xavier Thirioux

added warnings for useless variables (at verbose level 1)
- exact definition of 'useless' may be further refined
- display could certainly be improved

c1b14ce6 06/25/2014 02:33 PM Xavier Thirioux

work in progress:
- warnings for unused input/memory variables
- optimization of machine code

522938b5 06/25/2014 11:13 AM Pierre-Loïc Garoche

Split all functions of C backends in separate files

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

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

db1c5c00 06/24/2014 03:16 PM Pierre-Loïc Garoche

Extracted scheduling from machine code computation

97498b53 04/01/2014 06:03 PM Xavier Thirioux

still computing disjoint clock information (for reusing more variables)

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

- corrected causality bug (cf. previous commit)

e8c0f452 03/20/2014 03:41 PM Xavier Thirioux

liveness analysis improved. BUG found in causality wrt clocks...

3c48346d 03/19/2014 11:00 PM Xavier Thirioux

- modified example (arguments are now in the right order wrt clock declaration).
- debugged liveness analysis...

d4101ea0 03/19/2014 06:08 PM Xavier Thirioux

- reimplemented computation of dead variables
- added computation of a reuse policy (depending on types)
- not yet used though, would have to change code generation
in order to be useful...

6cf31814 03/18/2014 06:05 PM Xavier Thirioux

added liveness analysis for reusing dead variables. Not yet used.

Moved files to trunk in lustre_compiler
