Re: Dwarf views broken on ia64?

My main remaining concern is reordering of view labels, e.g., given:

.loc f1 l1 c1 view .LVU1
insn1
.loc f2 l2 c2 view .LVU2
insn2

could this get processed such that insn1 appears after insn2, and the
line number program gets to (f2,l2,c2) before (f1,l1,c1).  This would
break an assumption in the locview computing logic that assumes views
(within the same subsection) are issued in order.
