Subject: How to decide the what type is currently being used in tree_node?
Date: Fri, 19 Feb 2021 13:01:01 +0800	[thread overview]
Message-ID: <CAEQMQomk6rGC=+XyAnLnY4hQ_AAA+nzAPFSfAFfVQbAeqzJqKQ@mail.gmail.com> (raw)

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
