Matching usage of bool variables
In this example we write a semantic patch to match the uses of a variable having a user defined type. This tutorial explains how to name rules. We introduce two metavariable types, namely typedef and idexpression. Here we will be studying the following patch: @find_usage@ typedef bool; idexpression bool id; @@ * id@find_usage@ typedef …
