# The purpose of this test is to make sure that 8 byte instructions do not
# cross 64 byte boundaries. If an 8 byte instruction is about to cross such
# a boundary then a nop should be added so that the 8 byte instruction starts
# 4 bytes later and does not cross the boundary.
# This instruction is 8 bytes: paddi 1, 2, 8589934576, 0
# This instruction is 4 bytes: addi 2, 3, 15
