--- Comment #14 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Perhaps move the condition preparation statements including the surrounding
CLEANUP_STMT into {FOR,WHILE}_COND_PREP and insert into that CLEANUP_STMT first
operand some new tree as a temporary placeholder for eventually the
{FOR,WHILE}_COND, optional continue label and FOR_EXPR and keep the
{FOR,WHILE}_COND and FOR_EXPR as separate operandss at a different level even
when they actually will replace the placeholder.
