This is what I get:
% guile-tools compile -o ALL.go ALL.scm
ERROR: Value out of range 0 to 255: 633
89.725u 7.472s 1:37.29 99.8% 0+0k 0+0io 4pf+0w
Just for fun, I tried out a Fibonacci numbers benchmark (see below).
Here are the results:
Guile 1.9.1: 128.8 secs (compiled)
SCM version 5e5: 126.5 secs (interpreted)
Hobbit compiled: 2.2 secs (compiled)
Its a pity that you decided to write your own compiler instead
of continuing development with Hobbit :-(
Here is the test program:
(define /i '())
(define (@fib /n)
(if (<= /n 1)
1
(+ (@fib (- /n 1)) (@fib (- /n 2)))))
(let ((var-save /i) (for-step 1) (for-end 40))
(set! /i 1)
(let for-loop ()
(cond ((or (and (> 1 0) (<= /i for-end))
(and (< 1 0) (>= /i for-end)))
(begin
(display "fib(")
(begin
(display /i)
(begin
(display ") = ")
(begin
(display (@fib /i))
(newline)
(force-output)))))
(set! /i (+ /i for-step))
(for-loop))
(#t #t)))
(set! /i var-save))
(exit)
