Hi! Thanks for taking the time of writing a proof of concept program.
So far from what i've been reading it seems ok (didnt have much time
to check the entire code in detail) althought the real
advantage of compiling such graphs is when they are very large and
stack/buffer and indirection operations start to really slow it down.
Still, even whith this, i get (please tell me if these are correct):
realtime code: (./main)
real 0m1.005s
user 0m0.970s
sys 0m0.030s
runtime code: (./gen)
real 0m0.435s
user 0m0.370s
sys 0m0.060s
three seems to be quite a difference!
