Further restructuring:- arrow.ml* to define basic builder for arrow (node, name, ...)- machine_code_common similar to corelang but for machine_code (printers, some builders, ...)- machine_code restricted to the translatation from normalized nodes to machines
MLI for normalization and machine_code.Structs defining machines are now in machine_code_types
- Makefile: solved dependency problem when compiling include lusi- Renamed type declarations as lustre_types and machine_code_types
[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
[general] Refactor get_node_eqs to produce (eqs, auts) with automatons
First working version of algebraic loop resolution. Disabled by default.
Refactored some code: optimization of machine
Refactored EMF backend. Handle now the call to existing math and conv libraries
Renamed ISet of Machine_code to VSet: was sets of variable and was conflicting with ISet from Utils which carries strings.
Improved EMF backend. Working on the whole fmcad suite
Solved bug in machine code generation for asserts that contain memories
Cleaned horrible ocaml practice (optional parameters and mli issues)
- Added a field lustre_eq to machine instruction in order to record the originating lustre equation- EMF backend now impose the optimization level to be set to 0 in order to avoid equation elimination that would render traceability difficult- Options.ml has been split into Options.ml / Options_management.ml. Options.ml only contains references and no functions
- Addtional encapsulation of machine_code instr in a struct to enable future extension of type with more metadata.- Improved EMF backend with META information
EMF backend now relies on machine code representation.Impact:- EMF backend has an extra machines argument- specific option to avoid merge of ite constructs- set_backend function to improve backend selection
Most code was extracted from seahorn_backend through c0f8
Improved include folders behaviors:- allow multiple -I dir, will be used in order (first one declared is first used)
- when declaring a global library #open <foo>, foo is first checked in local folders, than in global one (install path). This does not apply to local libraries opened with #open "foo".
[bug solved] issues with asserts (invalid eqs scheduling)
Removing silly warning message
Merge branch 'unstable' into merging_pluginsNon regression results were similar to master branch
Solved a bug in the compilation of asserts. Now different behavior depending on the backend:functional: keep it as isnon func: introduce a fresh local var v and replace assert(e) by v=e; assert (v);
Merge branch 'github_master' into integ_github_jan10Intregrate all modifs by Teme et al
adding -I options to lustrec
updating to onera version 30f766a:2016-12-04
...
full merge of salsa/mpfr and master
Updated to onera_git commit version 9421e24
Resolved conflict when merging salsa with horn_encoding. The current branch is the most updated.
Merge branch 'salsa' into merge_salsa_horn_2Postponed conflicts to be solvedConflicts: src/_tags src/backends/Horn/horn_backend.ml src/machine_code.ml src/main_lustre_compiler.ml src/myocamlbuild.ml.in src/optimize_machine.ml
Introduced the opposite of Reset call: NoReset. This simplify the general compilation process and makes the code more symmetric, hence simpler and clearer code.
Merge branch 'master' into horn_enum_types
Conflicts: src/backends/Horn/horn_backend.ml
major branche merging salsa/mpfr with trunk
bug corrected: in some cases, local const vars were assigned twice

Two fresh branches :)to manage enum and arrays in the horn backend.
first commit
corrected a small bug when -horn option was active
git-svn-id: https://cavale.enseeiht.fr/svn/lustrec/lustre_compiler/trunk@450 041b043f-8d7c-46b2-b46e-ef0dd855326e
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...
modifed / to div in horn backend
git-svn-id: https://cavale.enseeiht.fr/svn/lustrec/lustre_compiler/trunk@420 041b043f-8d7c-46b2-b46e-ef0dd855326e
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.

- Dealt with compiling lusic from distant lusi files.- Header now do not allow the generation of function previously declared as C prototype
git-svn-id: https://cavale.enseeiht.fr/svn/lustrec/lustre_compiler/trunk@375 041b043f-8d7c-46b2-b46e-ef0dd855326e

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...

- 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

- 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...

added warnings for useless variables (at verbose level 1) - exact definition of 'useless' may be further refined - display could certainly be improved
git-svn-id: https://cavale.enseeiht.fr/svn/lustrec/lustre_compiler/trunk@290 041b043f-8d7c-46b2-b46e-ef0dd855326e

git-svn-id: https://cavale.enseeiht.fr/svn/lustrec/lustre_compiler/trunk@268 041b043f-8d7c-46b2-b46e-ef0dd855326e

- 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...

Added declaration/definition of stateless/stateful nodes. The 'function' keyword is for stateless nodes only, the 'node' keyword is any kind of node. Improves compilation and paves the way for more optimizations.
git-svn-id: https://cavale.enseeiht.fr/svn/lustrec/lustre_compiler/trunk@202 041b043f-8d7c-46b2-b46e-ef0dd855326e
