# The purpose of this test is to check that when an alignment nop is added
# it is added correctly with resepect to the labels in the .s file.
# The test contains 3 labels at the end (1:, 2:, 3:). The label 2: is on the
# same line as an unaligned 8 byte instruction. The desired behaviour is to have
# the alignment nop inserted after the 1: label but before the 2: label. The
# branch to 1: should jump to 3c: and the branch to 2: should jump to 40:.
