+; We used to generate really horrible code for this function. The main cause was
+; a lack of a custom lowering routine for an ISD::SELECT. This would result in
+; two "it" blocks in the code: one for the "icmp" and another to move the index
+; into the constant pool based on the value of the "icmp". If we have one "it"
+; block generated, odds are good that we have close to the ideal code for this:
+;
+; CHECK-NEON: _f8:
+; CHECK-NEON: movw [[REGISTER_1:r[0-9]+]], #1123
+; CHECK-NEON-NEXT: movs [[REGISTER_2:r[0-9]+]], #0
+; CHECK-NEON-NEXT: cmp r0, [[REGISTER_1]]
+; CHECK-NEON-NEXT: adr [[REGISTER_3:r[0-9]+]], #LCPI
+; CHECK-NEON-NEXT: it eq
+; CHECK-NEON-NEXT: moveq [[REGISTER_2]], #4
+; CHECK-NEON-NEXT: ldr
+; CHECK-NEON: bx
