With GCC only, you can get the address of a label like this:
static void *array[] = { &&foo, &&bar, &&hack };
goto *array[i];
foo:
bar:
hack:
Of course, this does exactly the same as a switch.
Are you sure switch makes the same kind of code as above ? I thougth it
made a lot of compare/next steps !
Guess I need to look more into the generated asm output (not been doing
this for a while) !
But it becomes interesting
when you replace the opcodes of the instructions in the bytecode with the
addresses of the labels so you can directly jump to the address of the next
instruction without falling back in the loop code.
That would be wery strange code indeed, and I will be happy if switch
make the indirect goto jump for me, as this will be quite speedy ! Next
step will be a compiler :-)
