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.

f66c9045df Special case for merge in the scheduling 
For merge equations, the generated code will be 
on a different rate than the activation clock of
the equation.

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.

06e997e0c8 Fix for -mall 
Do not share memories and outputs if they are not

by the C compiler less efficient.
