I'm reading the paper given by Mark. Though I confused with this "call
convention" problem, I thought the point maybe that we can hardly get a
optimized result all by GCC. But if we arrange it manually or restrict
it to certain call convention except cdecl, it's not perfect for
GCC?(But I don't think we need perfect) According to the paper, some
scheme compiler provided "tail call" based on a modified standard C
compiler. I think it's similar to arrange/restrict solution.
I'm not sure if my understanding is correct. Anyway, I'll finish reading
this paper.
