bogus warnings relating to type of function with gcc attributes

Created: 22/Apr/10 04:13 PM   Updated: 22/Apr/10 09:18 PM
Component/s: C frontend
Affects Version/s: None
Fix Version/s: None

Environment: NetBSD/i386


 Description  « Hide
The following code

  struct foo {
          int a;
  } *foo;

  struct foo *bar(void) __attribute__((__unused__));

  struct foo *bar(void)
  {
          return foo;
  }

produces a "warning: illegal structure pointer combination" at the return statement when compiled. __unused__ is just an illustration as any attribute causes it and, the warning goes away if I remove the attributes.

I guess that the code is not comparing the correct node rather than the attribute modifying the type. Does chkpun() need to be made aware of attributes?

Correct, the struct type checking needed a slight modification. Fixed now.
