TWiki . Octave . WhatsGoingOn


January 14th

Refactored function specialization, so it can be reused is both the type inferencer and the Octave partial evaluator. In fact, it is already used in the new versions of the given tools.

Known issues,

The partial evaluator is now reusing the octave optimizer, Octave-SuperOpt, which combines constant propagation, copy propagation and common subexpression elimination.

Weekend thoughts

Note to self: borrow FC3 DVD from Arthur to gather RPM's for making of an octavec RPM.

New year, broken computer. Time to check what is bothering me still in the compiler, results of old code.

And a lot more I can't think of at the moment...

Working on a rewrite of the type inferencer. Why do I have the need to rewrite everything :-S ? Anyway, it gives a good insight in what as working in the old situation and what wasn't working (correctly).

Today it is times to add the rules for binary operators. Not difficult, just a lot of work. Next issue will be type based function specialization.

When the type inferencer is finished, I will define a backward propagation strategy, which we will use to rewrite optimizations like dead code elimination.

We should definitely look at the following optimizations:
