9.21.6.2 Special Characters
...........................
Line comments are introduced by the '|' character appearing anywhere on
a line, unless the '--bitwise-or' command-line option has been
specified.
An asterisk ('*') as the first character on a line marks the start of
a line comment as well.
A hash character ('#') as the first character on a line also marks
the start of a line comment, but in this case it could also be a logical
line number directive (Comments) or a preprocessor control
command (Preprocessing). If the hash character appears
elsewhere on a line it is used to introduce an immediate value. (This
is for compatibility with Sun's assembler).
Multiple statements on the same line can appear if they are separated
by the ';' character.
