-; LSR should only check for valid address modes when the IV user is a
-; memory address.
-; svn r158536, rdar://11635990
-;
-; Note that we still don't produce the best code here because we fail
-; to coalesce the IV. See <rdar://problem/11680670> [coalescer] IVs
-; need to be scheduled to expose coalescing.

-;The chosen solution requires 4 regs, with addrec cost 1, plus 3 base adds, plus 2 setup cost:

-;    reg(%v3) + reg({0,+,-1}<%while.cond.i.i>) + imm(1)
-;  LSR Use: Kind=ICmpZero, Offsets={0}, widest fixup type: i32
-;    reg(%v3) + reg({0,+,-1}<%while.cond.i.i>)
-;  LSR Use: Kind=Address of i32, Offsets={0}, widest fixup type: i32*
-;    reg((-4 + (4 * %v3) + %v1)) + 4*reg({0,+,-1}<%while.cond.i.i>)
