Hi Gus,

However, it seems like it only works in GCC if goto(label1) instruction is
used... Is there any other way to do this?

you might want to have a look at this online doc about label-as-values:

http://gcc.gnu.org/onlinedocs/gcc/Labels-as-Values.html

If I remember correctly, this is not part of an official standard (except the GNU C standard), so the portability of your code might decrease.

Best regards,
Andi
