Another aspect was improved also for the Coccinelle software.
The following SmPL script variant can point source code places out for
further considerations.
@display@
binary operator bo;
expression e1, e2, e3, call;
identifier var;
statement is, es;
type t;
@@
*t var = e1;
... when != if ( \( var bo e2 \| var \) ) is else es
when != call(..., var, ...)
when exists
*var = e3
But it seems that data flow analysis would be needed to exclude remaining
false positives for such a source code search pattern.
