/*
 * Purpose: test example, verify the soundness of the vrmaxh operation.
 *
 * The maximum between  0x0002000300010005 and 0x0003000200020007 is
 * 0x0003000300020007.
 *
 *      input:  r1 = 0x00010003 r0 = 0x00010005 r3 = 0x00030002 r2 = 0x00020007
 *     output:  r1 = 0x00030003 r0 = 0x00020007
