There is now three options for memory allocation:
- -only-linear activates only the linear
annotations (with typing and code generation)
- -only-memalloc does only memory allocation
- -memalloc does both
When linear typing is not activated, linearity
annotations are ignored (the signature in the .epi
does not contain the annotations)
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.
I introduced a notion of extended values in Obc expressions,
replacing the Epattern constructor. Patterns may now only
occur at their rightful place, on the left of an assignment.
This change allows to index global constant arrays.
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.
Added graphical simulator hepts
Added option -hepts to the compiler: this option formats the output of the simulation loop
to fit with hepts (currently working only on C target code). Typically, suppresses all
"decoration" output, like input or output names, and prints output on single lines.
Currently not implemented in hepts: array types.
Usage: to simulate the node Modulename.f:
heptc -target c -s f -hepts modulename.ept
gcc modulename_c/*.c -o ./f_sim
hepts -mod Modulename -node f -exec ./f_sim
The compiler still does not support unsafe functions that well. For example, putting an assert()/exit() in an automaton's state does not work correctly.
- Added "z3z" target language, calling sigali code generation
- a_id is application id, so as to identify node applications; added
to Minils AST. a_id is given on hept2mls pass.
This is needed for the controller execution from controller synthesis.
