Each version has much in common with the others, -including object file formats, most assembler directives (often called -\&\fIpseudo-ops\fR) and assembler syntax. -.PP -\&\fBas\fR is primarily intended to assemble the output of the -\&\s-1GNU\s0 C compiler \f(CW\*(C`gcc\*(C'\fR for use by the linker -\&\f(CW\*(C`ld\*(C'\fR. Nevertheless, we've tried to make \fBas\fR -assemble correctly everything that other assemblers for the same -machine would assemble. -Any exceptions are documented explicitly. -This doesn't mean \fBas\fR 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. -.PP -Each time you run \fBas\fR it assembles exactly one source -program. The source program is made up of one or more files. -(The standard input is also a file.) -.PP -You give \fBas\fR a command line that has zero or more input file -names. The input files are read (from left file name to right). A -command line argument (in any position) that has no special meaning -is taken to be an input file name. -.PP -If you give \fBas\fR no file names it attempts to read one input file -from the \fBas\fR standard input, which is normally your terminal. You -may have to type \fBctl-D\fR to tell \fBas\fR there is no more program -to assemble. -.PP -Use \fB\-\-\fR if you need to explicitly name the standard input file -in your command line. -.PP -If the source is empty, \fBas\fR produces a small, empty object -file. -.PP -\&\fBas\fR may write warnings and error messages to the standard error -file (usually your terminal). This should not happen when a compiler -runs \fBas\fR automatically. Warnings report an assumption made so -that \fBas\fR could keep assembling a flawed program; errors report a -grave problem that stops the assembly. -.PP -If you are invoking \fBas\fR via the \s-1GNU\s0 C compiler, -you can use the \fB\-Wa\fR option to pass arguments through to the assembler. -The assembler arguments must be separated from each other (and the \fB\-Wa\fR) -by commas. For example: -.PP -.Vb 1 -\& gcc \-c \-g \-O \-Wa,\-alh,\-L file.c -.Ve -.PP -This passes two options to the assembler: \fB\-alh\fR (emit a listing to -standard output with high-level and assembly source) and \fB\-L\fR (retain -local symbols in the symbol table). -.PP -Usually you do not need to use this \fB\-Wa\fR mechanism, since many compiler -command-line options are automatically passed to the assembler by the compiler. -(You can call the \s-1GNU\s0 compiler driver with the \fB\-v\fR option to see -precisely what options it passes to each compilation pass, including the -assembler.) -.SH "OPTIONS" -.IX Header "OPTIONS" -.IP "\fB@\fR\fIfile\fR" 4 -.IX Item "@file" -Read command-line options from \fIfile\fR.
