[patch] math.ops, out PMC

Hey, Attached is a small patchlet, that allows the following code to execute: .pcc_sub _main prototyped .sym PerlUndef a a = new PerlUndef a = 10 + 5 print a .end And avoids having to instead do: .pcc_sub _main prototyped .sym PerlUndef a a = new P

Calling functions in IMCC

Hey, I'm having problems figuring out how to pass parameters to a function with the current imcc. It either segfaults (in hash_str() from find_basic_blocks()) or gives me 'No entries on the UserStack', depending on how I do it wrong. :) Does anyone have a minimal example of using imcc to call

Re: Proposal: parrot-compilers list

The reason I think parrot-compilers would be useful, is that its dedicated to helping people (like me) write compilers for parrot, whereas (in my understanding), perl6-internals@ is really about the development of the vm itself (I would subscribe to both). I see parrot-compilers@ as opening up

Re: Optimizations for Objects

That's all fine and good, and the generic method cache will help here. However... we can do better. What I'm thinking of is caching the actual found method PMC pointer in the class somewhere (hanging off the vtable or in the class' attributes or something) such that we don't actually have to *d
