If the @code{TREE_TYPE} of the @code{CONSTRUCTOR} is an
@code{ARRAY_TYPE}, then the @code{TREE_PURPOSE} of each element in the
! @code{TREE_LIST} will be an @code{INTEGER_CST} or a @code{RANGE_EXPR} of
! two @code{INTEGER_CST}s. A single @code{INTEGER_CST} indicates which
! element of the array (indexed from zero) is being assigned to. A
! @code{RANGE_EXPR} indicates an inclusive range of elements to
! initialize. In both cases the @code{TREE_VALUE} is the corresponding
! initializer. It is re-evaluated for each element of a
! @code{RANGE_EXPR}. If the @code{TREE_PURPOSE} is @code{NULL_TREE}, then
! the initializer is for the next available array element.
