Thank you. It seems I've not found my error then. build_tree_cfg is
called 4 times before my pass. I guess it's one for each function I
have in my source file.
So, how come no bbs are created? Is there any other way to test where
the problem lies?
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!
