Each version has much in common with the others, +including object file formats, most assembler directives (often called +\c +.I pseudo-ops)\c +\& and assembler syntax. + +For information on the syntax and pseudo-ops used by GNU \c +.B as\c +\&, see `\|\c +.B as\c +\|' entry in \c +.B info \c +(or the manual \c +.I +.I +Using as: The GNU Assembler\c +\&). + +\c +.B as\c +\& is primarily intended to assemble the output of the GNU C +compiler \c +.B gcc\c +\& for use by the linker \c +.B ld\c +\&. Nevertheless, +we've tried to make \c +.B as\c +\& assemble correctly everything that the native +assembler would. +This doesn't mean \c +.B as\c +\& 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 \c +.B as\c +\& 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 \c +.B as\c +\& is given no file names it attempts to read one input file +from the \c +.B as\c +\& standard input, which is normally your terminal. You +may have to type \c +.B ctl-D\c +\& to tell \c +.B as\c +\& there is no more program +to assemble. Use `\|\c +.B \-\^\-\c +\|' if you need to explicitly name the standard input file +in your command line. + +.B as\c +\& may write warnings and error messages to the standard error +file (usually your terminal). This should not happen when \c +.B as\c +\& is +run automatically by a compiler. Warnings report an assumption made so +that \c +.B as\c +\& could keep assembling a flawed program; errors report a +grave problem that stops the assembly. + +.SH OPTIONS +.TP +.BR \-a \||\| \-al \||\| \-as +Turn on assembly listings; `\|\c +.B \-al\c +\&\|', listing only, `\|\c +.B \-as\c +\&\|', symbols +only, `\|\c +.B \-a\c +\&\|', everything. +.TP +.B \-D +This option is accepted only for script compatibility with calls to +other assemblers; it has no effect on \c +.B as\c +\&. +.TP +.B \-f +``fast''--skip preprocessing (assume source is compiler output). +.TP +.BI "\-I\ " path +Add +.I path +to the search list for +.B .include +directives. +.TP +.B \-k +Issue warnings when difference tables altered for long displacements. +.TP +.B \-L +Keep (in symbol table) local symbols, starting with `\|\c +.B L\c +\|' +.TP +.BI "\-o\ " objfile +Name the object-file output from \c +.B as +.TP +.B \-R +Fold data section into text section +.TP +.B \-v +Announce \c +.B as\c +\& version +.TP +.B \-W +Suppress warning messages +.TP +.IR "\-\^\-" "\ |\ " "files\|.\|.\|." +Source files to assemble, or standard input (\c +.BR "\-\^\-" ")" +.TP +.BI \-A var +.I +(When configured for Intel 960.) +Specify which variant of the 960 architecture is the target. +.TP +.B \-b +.I +(When configured for Intel 960.) +Add code to collect statistics about branches taken. +.TP +.B \-norelax +.I +(When configured for Intel 960.) +Do not alter compare-and-branch instructions for long displacements; +error if necessary. +.TP +.B \-l +.I +(When configured for Motorola 68000). +.br +Shorten references to undefined symbols, to one word instead of two. +.TP +.BR "\-mc68000" "\||\|" "\-mc68010" "\||\|" "\-mc68020" +.I +(When configured for Motorola 68000). +.br +Specify what processor in the 68000 family is the target (default 68020) + +.PP +Options may be in any order, and may be +before, after, or between file names. The order of file names is +significant. + +`\|\c +.B \-\^\-\c +\|' (two hyphens) by itself names the standard input file +explicitly, as one of the files for \c +.B as\c +\& to assemble. + +Except for `\|\c +.B \-\^\-\c +\|' any command line argument that begins with a +hyphen (`\|\c +.B \-\c +\|') is an option. Each option changes the behavior of +\c +.B as\c +\&. No option changes the way another option works. An +option is a `\|\c +.B \-\c +\|' followed by one or more letters; the case of +the letter is important. All options are optional. + +The `\|\c +.B \-o\c +\|' 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: +.br +.B +as\ \ \-o\ \ my\-object\-file.o\ \ mumble.s +.br +.B +as\ \ \-omy\-object\-file.o\ \ mumble.s + +.SH "SEE ALSO" +.RB "`\|" as "\|'" +entry in +.B +info\c +\&; +.I +Using as: The GNU Assembler\c +\&; +.BR gcc "(" 1 ")," +.BR ld "(" 1 ")." + +.SH COPYING +Copyright (c) 1991, 1992 Free Software Foundation, Inc. +.PP +Permission is granted to make and distribute verbatim copies of +this manual provided the copyright notice and this permission notice +are preserved on all copies. +.PP +Permission is granted to copy and distribute modified versions of this +manual under the conditions for verbatim copying, provided that the +entire resulting derived work is distributed under the terms of a +permission notice identical to this one. +.PP +Permission is granted to copy and distribute translations of this +manual into another language, under the above conditions for modified +versions, except that this permission notice may be included in +translations approved by the Free Software Foundation instead of in +the original English. -- 2.30.2
