e9269f1c4a optimize (let ([x (let~ ([y M]) N)]) P) to (let~ ([y M]) (let ([x N]) P)) 
which helps expose unboxing opportunities with multiple-value binding

a6ec6a7e30 change bytecode optimizer's representation of `let' 
- represent RHSes as before allocating stack positions
   for bindings, instead of after, which makes certain
   transformations simpler; this does not effect the
   final bytecode form that's is saved in a ".zo"

d2894e7a8e added in a use of Shu-yu's opt/c to see if it helps (which it does for complex contracts) 2010-08-07 14:35:06 -05:00
Robby Findler
40cde743a9 Got to the point where I can run some timings to see how well ->i does. 
Here are the results, each contract put on the same function, namely:
(λ (x y) (+ x y))

1: (-> number? (<=/c 0) any)
2: (->i ([x number?] [y (<=/c 0)]) any)
3: (->i ([x number?] [y (x) (<=/c x)]) any)
4: (->d ([x number?] [y (<=/c 0)]) any)
5: (->d ([x number?] [y (<=/c x)]) any)

Taking f1 as the baseline, these are the relative times for calling
that thing over and over in a loop, supplying -1 as both of the
arguments:

f2: 1.01x
f3: 4.15x
f4: 21.1x
f5: 21.5x
