Actually we do have one stack frame shrinking pass already. It depends on where the bloat is comming from - we can pack (with some limitations) memory used by structures/arrays used by different inline functions or lexical blocks. We don't do any packing of spilled registers nor shring wrapping other compilers sometimes implement.
Ah. So there's already some shrinkage. I don't think i can blame spilling for all that waste, but then i also have no idea what that "shring wrapping" involves. Also i think it's only a bit worse with C++ where some idioms appear to cause more trouble.
It would be nice to have a cheat sheet of do and don't :) It seems my previous obese mail got axed a bit, http://ompf.org/vault/frontend.ii.bz2 http://ompf.org/vault/rt_render_packet.ii.bz2
