This is just an experiment on [1], the interpreter logic is identical to the
original.
From [2] I assume the code follows the Unlicense License. You can assume the
same license from me on the shell scripts and interp_call.c (function table
variant).
The results on a 100-byte randomly generated program:
$ ./test.sh
+ ./main
131 131 131
0
+ echo
+ ./main_switch
96
real 0m2.022s
user 0m2.019s
sys 0m0.003s
+ echo
+ ./main_cgoto
96
real 0m0.855s
user 0m0.854s
sys 0m0.001s
+ echo
+ ./main_call
96
real 0m2.069s
user 0m2.069s
sys 0m0.000s
+ echo
+ echo all done
all done
