Just for my own education, since I've been wondering how to write comments
in tests suitable for all (or at least most) targets: # isn't a universal
comment char either (having a different meaning e.g. on Arm). In
gas/testsuite/gas/all/quoted-sym-names.s I did use /**/ which looks to
have worked quite well ... Elsewhere I find ";#" in use.
