FILES
/usr /tmp/as[l-6]XXXXXX temporary files
SEE ALSO
ld(l), m4( 1), nm(l), strip(l), a.out(4).
WARNING
BUGS
If the -m ( m4 macro pre-processor invocation) option is used, l
keywords for m4 (see m4 (1)) cannot be used as symbols (variables,
functions, labels) in the input file since m4 cannot determine
which are assembler symbols and which are real m4 macros.
Use the -b or -w option only when undefined symbols are known
to refer to locations representable by the specified default displacement.
Use of either option when assembling a file containing a
reference to a symbol that is to be resolved by the loader can lead
to unpredictable results, since the loader may be unable to place
the address of the symbol into the space provided.
The . align assembler directive is not guaranteed to work in the
.text section when optimization is performed.
Arithmetic expressions may only have one forward referenced
symbol per expression.
