false negative when using not about weggli HOT 2 OPEN

[I am not a maintainer, just curios]
I believe the second case you wrote is the right way to query what you want. In the first one you query for a call of "function" that gets as a parameter another call for a function that gets &param.

The interesting thing here is actually that this query matches:

weggli '{
    $function(_(&$param));
    $function(&$param);
}' .

/tmp/src/./a.c:1
void fun(){
    int param;
    int foo = 1;
    function(&param); // <----- These two lines actually match
    function(&param);
}

As the first call to "function" has no parameter that is by itself a call for a function

from weggli.

A

{
    function();        
    NOT: foo = _;
    function();
}

also works. Same as

{
    function(&$param);        
    NOT: foo = _;
    function(&$param);
}

or

{
    function(_);        
    NOT: foo = _;
    function(_);
}

Looks like the _(...) expressions with not throws it off.
