As a side note, if I instead try to access BBs through FOR_EACH_BB_FN
I get the basic blocks I wanted. :)
struct function *fdecl = DECL_STRUCT_FUNCTION(node->decl);
basic_block bb;
FOR_EACH_BB_FN(bb, fdecl) {
    printf("For each bb!\n");
  }

This will print "For each bb!" a couple of times for each function.
Seems to be working this way around! :) heh!
