llcppsigfetch:undef custom type refer error #882

Open luoliwoshang opened 5 days ago

luoliwoshang commented 5 days ago

For undefined type references, an error type should be returned instead of the type corresponding to int.

llcppsigfetch --extract "void fn(a *undef);" -temp=true -cpp=false

the under type show as a int.
