Contracts can now comprise a list of objectives (in any order).
One objective can be (e being a Boolean heptagon expression) :
- invariance, with the syntax "enforce e"
- reachability, "reachable e"
- attractivity, "attractive e"
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.
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.
- Global_mapfold is used to iterate over types
defined in Types or Signature (the iterators
from Types were moved here)
- Mls_mapfold to iterate over Minils AST (we
do not iterate over clocks yet: is it useful ?)
