            Bug ID: 74765
           Summary: missing uninitialized warning (parenthesis,
                    TREE_NO_WARNING abuse)
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: manu at gcc dot gnu.org
  Target Milestone: ---

int foo(int x, int y)
{
    int i;
    if ((i ==0)) return x;
    return y;
}

int foo2(int x, int y)
{
    int i;
    if (i ==0) return x;
    return y;
}

The extra parenthesis hide the -Wuninitialized warnings for foo(). Related to
PR25733. Different from PR74762.
