           Summary: You can't know the number of arguments from the non_null
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: AST
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: bolzoni at cs.unipr.it
                CC: llvmbugs at cs.uiuc.edu, bagnara at cs.unipr.it

After calculating the AST of the following code:
void f(char* p, char* q)
  __attribute__((nonnull (1)));
void f();

The clients can't examine the value of the nonnull attribute of the second
declaration since they can not know the number of arguments.

I think it is pretty straightforward to fix since the NonNullAttr class do have
a `number of arguments' member, but being private it can't be read.
It is enough adding a get function.
