; This tests icmp operations that do not map directly to NEON instructions.
; Not-equal (ne) operations are implemented by VCEQ/VMVN. Less-than (lt/ult)
; and less-than-or-equal (le/ule) are implemented by swapping the arguments
; to VCGT and VCGE. Test all the operand types for not-equal but only sample
; the other operations.
