This helped solve a few bugs with linear types,
for instance when using automata.
The intermediate code is not well-typed (wrt to
linear types only), after the encoding of automata.
( = ) in pervasives is a stub, it will be typed in a polymorphic way.
This is necessary to have a simple way to transform exp into a static_exp
even when there is the = operator.
Ewhen is now the only case of possible recursion for minils exps.
This add was motivated by equations like :
(y,z) = f(x) when c
This equation to be correctly normalized in minils before needed :
y',z' = f(x)
y = y' when c
z = z' when c
But this new variables where needless since the final translation of when c
is the identity.
in the old fix was missing the renaming, and there was wrong equations
order :
f () returns x
[here rename x by mem_x]
mem_x = fby ...
x = mem_x
so the simplest was :
f () returns out_x
var x;
[ nothing to do]
out_x = x
x = fby ...
pay attention to the order of equations since we are after the
scheduling..
probably it should be done before the scheduling anyway ?
Created two new files:
- utilities/global/compiler_options.ml: contains
the options that can be set using the cli
- utilities/global/errors.ml: contains global
errors definition
Misc now only contains helper functions that have
nothing to do with the ast or the compiler.
Warn as error for partial match.
Warn for unused variables : added some TODO to check.
PS : I'll deal with callgraph which is doing things that Modules does.
- (v1, v2, ... ) fby (e1, e2, ...) is translated to
(v1 fby e1, v2 fby e2, ...)
This has made the code even more complex. This will
need to be refactored at some point.
- Static are used for consts in Heptagon and Minils.
For now, node static parameters remain int only
(ie they are type parameters). Do we need more ?
- Also updated Parsetree AST to the recent changes
in API
There are now 3 kinds of nodes: Eprim : primitive
nodes, Enode: nodes with memory, Efun: nodes
without memory.
Typing now sets correct eq_statefull and b_statefull
for equations and blocks. Resets are only added
when a node with memory is called.
The calling convention is the generated code needs
to be modified so that we can remove the context
for nodes without memory.
-* Séparation du fichier minils avec création de mls_utils
-* Lexer et Parser qui fonctionnent (pas complets encore)
-* Use of menhir with --explain pour debug du parser
-* Quelques refactoring (ident/name...)
