            Bug ID: 98097
           Summary: Missing warning about strcmp (char[4], "BARZ")
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rguenth at gcc dot gnu.org
  Target Milestone: ---

#include <string.h>

struct info {
   char type[4];
   unsigned int status;
};

int foo (struct info *i)
{
  return strcmp (i->type, "ECKD") == 0;
}

Does not warn with -Wstring-compare, the variant with i passed by value does.
