9.35.3.1 Special Characters

The presence of a ‘#’ on a line indicates the start of a comment that extends to the end of the current line.

If a ‘#’ appears as the first character of a line then the whole line is treated as a comment, but in this case the line could also be a logical line number directive (see Comments) or a preprocessor control command (see Preprocessing).

If the assembler has been configured for the ppc-*-solaris* target then the ‘!’ character also acts as a line comment character. This can be disabled via the -mno-solaris command line option.

The ‘;’ character can be used to separate statements on the same line.
