GNU aaaassss is really a family of assemblers. If you use (or have
used) the GNU assembler on one architecture, you should find
a fairly similar environment when you use it on another
architecture. Each version has much in common with the
others, including object file formats, most assembler
directives (often called _p_s_e_u_d_o-_o_p_s) and assembler syntax.
For information on the syntax and pseudo-ops used by GNU aaaassss,
see `aaaassss' entry in iiiinnnnffffoooo (or the manual _U_s_i_n_g _a_s: _T_h_e _G_N_U
_A_s_s_e_m_b_l_e_r).
aaaassss is primarily intended to assemble the output of the GNU C
compiler ggggcccccccc for use by the linker lllldddd. Nevertheless, we've
tried to make aaaassss assemble correctly everything that the
native assembler would. This doesn't mean aaaassss always uses
the same syntax as another assembler for the same
architecture; for example, we know of several incompatible
versions of 680x0 assembly language syntax.
Each time you run aaaassss it assembles exactly one source
program. The source program is made up of one or more
files. (The standard input is also a file.)
If aaaassss is given no file names it attempts to read one input
file from the aaaassss standard input, which is normally your
terminal. You may have to type ccccttttllll----DDDD to tell aaaassss there is no
more program to assemble. Use `--------' if you need to
explicitly name the standard input file in your command
line.
aaaassss may write warnings and error messages to the standard
error file (usually your terminal). This should not happen
when aaaassss is run automatically by a compiler. Warnings report
an assumption made so that aaaassss could keep assembling a flawed
program; errors report a grave problem that stops the
assembly.

----aaaa|----aaaallll|----aaaassss
Turn on assembly listings; `----aaaallll', listing only, `----aaaassss',
symbols only, `----aaaa', everything.
----DDDD This option is accepted only for script compatibility
with calls to other assemblers; it has no effect on aaaassss.
----ffff ``fast''--skip preprocessing (assume source is compiler
output).
----IIII _p_a_t_h
Add _p_a_t_h to the search list for ....iiiinnnncccclllluuuuddddeeee directives.
----KKKK Issue warnings when difference tables altered for long
displacements.
----LLLL Keep (in symbol table) local symbols, starting with `LLLL'

if necessary.

Options may be in any order, and may be before, after, or
between file names. The order of file names is significant.
`--------' (two hyphens) by itself names the standard input file
explicitly, as one of the files for aaaassss to assemble.
Except for `--------' any command line argument that begins with a
hyphen (`----') is an option. Each option changes the behavior
of aaaassss. No option changes the way another option works. An
option is a `----' followed by one or more letters; the case of
the letter is important. All options are optional.
The `----oooo' option expects exactly one file name to follow.
The file name may either immediately follow the option's
letter (compatible with older assemblers) or it may be the
next command argument (GNU standard).
These two command lines are equivalent:
aaaassss ----oooo mmmmyyyy----oooobbbbjjjjeeeecccctttt----ffffiiiilllleeee....oooo mmmmuuuummmmbbbblllleeee....ssss
aaaassss ----oooommmmyyyy----oooobbbbjjjjeeeecccctttt----ffffiiiilllleeee....oooo mmmmuuuummmmbbbblllleeee....ssss
