Hmm. Somewhere between eight thousand and the continuum. It's hard to remember after all the beatings. Still, I hope with enough work I can get promoted to "beef-smelling big-nosed barbarian" rank and lord it over the peons. :-) > I don't have any GCC credibility either but I once got an approving off-list > reply from Damian Conway while discussing coroutines in the context of > Perl 6 features -- which had me reading the university library's dusty > copy of Knuth's Art of Computer Programming IIRC the problem with Knuth's discussion is it's a bit opaque (quelle surprise). Also I think his are symmetric, and I'm afraid I've drunk the kool-aid in terms of asymmetric ones being simpler and clearer. However, they should require equivalent magic. > That said, my thoughts on the question of how to implement coroutines > using the GCC system are that it would best be done by abandoning the > idea of using the "native" stack for your program's "logical" stack. > ... > Why not implement your stacks as linked lists of dynamically allocated > stack frame objects, and coerce your language into primitives that > operate on those objects instead of trying to force things to be C-like? Hmm. Very good point. The biggest problem is probably the lack of interoperability with C. I think Lua may do exactly this, come to think of it, since I think it doesn't allow yields when there is a C function on the call sequence. > GCC might not be the best back end for your project. True. You can't beat it's market share, though. :-) > So the other thought, or the rest of the thought, is, why try to force > your language into GCC when it might be easier to force it into something > else? Well, aside from a possibly irrational fondness for GCC, I guess I didn't find something that was clearly better. Dustin
