# NOTE: this test checks multiple things:
# - that -aligncomm is not emitted for 1-byte alignment
# - that -aligncomm is emitted for the various alignments (greater than 1)
# - that the alignment is represented as a log_2 of the alignment
# - that the section switching occurs correctly
# - that functions after the switch also are emitted into the correct section
