5ac3a7f028 Redisable interference of scalars during scheduling 2012-02-10 11:33:09 +01:00
Adrien Guatto
0abb050a23 Changed linear typing for merge.
The new rule accepts that some branches of a linearly typed merge have linear
type Top, provided that at least one has type "lin". E.g.:

node f(x : int at r) returns (o : int at r)
var ck : bool;
let
  ck = true;
  o = merge ck (x whenot ck) 0;
tel

is now deemed valid.

6e2e2a9f47 Fixed bug in interference computation
To know the variables read by an equation, we should
only look at the clock of variables. Otherwise, 
there could be a problem for node calls that 
define new clocks.

db5f55b221 Fixed when of stateful exp with memalloc
As the expression inside the when will be called 
on a faster rhythm, we have to make sure not to
share it with a variable on the slow clock.
We do this by creating a new equation for the 
stateful exp.

  - -memalloc does both

annotations are ignored (the signature in the .epi

We should have:
       o = v fby e
     becomes
       mem_o = v fby e;
       o = mem_o

The old way would break with:
 v = true fby false fby v
that would generate unschedulable code.

81947eca40 Made linearity field not optional
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.

This got lost along the way when porting memalloc
to the new branch
