 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 (SeeComments) or a preprocessor control
 command (SeePreprocessing).  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.
