Hi all,
It seems that the Clang Static Analyzer may miss the analysis information of UnaryOperator. For example:
void func(int s) {
s++;
++s;
}
The example may be quite ridiculous…
My checker contains a method: void checkPostStmt(const Stmt *DS, CheckerContext &C).
I thought that it can capture any kind of Stmt. Since UnaryOperator is a subclass of Expr and Expr is a subclass of Stmt, I thought my checker can give me the analysis information of “s++” and “++s”. However, it returned nothing.
What’ more, I have tried to add another checkPostStmt() method in my checker. The declaration
of this method is void checkPostStmt(const UnaryOperator *Op, CheckerContext &C). The result is same with the previous one, it returned nothing.
In fact, I want to use Clang Static Analyzer to capture all kinds of UnaryOperator, including ‘s++/++s/s–/–’(IncrementOp/DecrementOp). *p(pointer dereference) and so on. So how can I get the analysis information of UnaryOperator in Clang Static Analyzer?
Thanks a lot.
