Hello, I noticed that tree_node is implemented as a union ( https://code.woboq.org/gcc/gcc/tree-core.h.html#tree_node). However, I cannot find a way of checking whether the current tree_node is really a base or type.
For instance, currently when I am using: is_gimple_constant(v) Given `v` as a tree type but NOT base type, the above statement would crash. I am thinking there should be a method like: is_tree_base(v) == false or something like this; however, I couldn't find one. Can anyone shed some lights on this? Thank you very much! best, Shuai
