            Bug ID: 102726
           Summary: Does not warn for enum constant in boolean context
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rguenth at gcc dot gnu.org
  Target Milestone: ---

We fail to warn for

                           gsi_replace (&gsi, call, GSI_SAME_STMT);

with

extern bool gsi_replace (gimple_stmt_iterator *, gimple *, bool);


and

enum gsi_iterator_update
{
  GSI_NEW_STMT,         /* Move the iterator to the first statement added.  */
  GSI_SAME_STMT,        /* Leave the iterator at the same statement.  */
  GSI_CONTINUE_LINKING  /* Move iterator to whatever position is suitable
                           for linking other statements in the same
                           direction.  */
};

presumably because GSI_SAME_STMT is 1
