- Many changes to make Hept2mls, mls2obc, etc
compile with the api changes
- Added Callgraph_mapfold: starting from a main
program, generates the list of instances of each
node necessary and creates them.
- Mls2seq deals with giving to the code generators
the correct source (mls or obc, wit or without
static parameters)
It is now possible to use parametrized nodes that
are defined in other files. For that to work, the
first file has to be compiled to an object file:
heptc -c mylib.ept
which creates a mylib.epo file. Compiling the main
file will then generate all the instances of
parametrized nodes from the lib (only the called
nodes will be compiled, but all the nodes in the
main file are compiled).
- 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 ?)
- 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
Generate it even if the node has no output. It
should be noted that it is impossible to call
a node without an output in an Heptagon program.
This is only useful to provide a simple interface
eg for the generation of main().
Functions take as arg:
- the inputs
- a 'f_out' structure: if there is at least one
input (whatever their type are)
- a 'f_mem' structure: containing memories and
contexts for child nodes. This is created only for
node (not for fun). A node declared statefull
without any memory will have an empty structure.
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.
