           Summary: Missed deprecation warnings for @property when using
                    getter/setter directly
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: objc
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: nic...@gcc.gnu.org


When you deprecate a @property, and then use the getter/setter directly, no
deprecation warning is currently produced.  That is, the following fails --

/* Contributed by Nicola Pero <nicola.p...@meta-innovation.com>, October 2010. 
*/
/* { dg-do compile } */

/* Test that deprecation warnings are produced when a setter/getter of
   a @property is used directly.  */

#include <objc/objc.h>

@interface MyClass
{
  Class isa;
  int variable;
} 
@property (assign, nonatomic) int property __attribute__ ((deprecated));
@end

void foo (void)
{
  MyClass *object = nil;

  if ([object property] > 0)  /* { dg-warning "is deprecated" } */
    {
      [object setProperty: 43]; /* { dg-warning "is deprecated" } */ 
    }
}

Thanks
