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 -\&\f(CW\*(C`as\*(C'\fR is primarily intended to assemble the output of the -\&\s-1GNU\s0 C compiler for use by the linker -\&. Nevertheless, we've tried to make \f(CW\*(C`as\*(C'\fR -assemble correctly everything that other assemblers for the same -machine would assemble. -Any exceptions are documented explicitly. -This doesn't mean \f(CW\*(C`as\*(C'\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 \f(CW\*(C`as\*(C'\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 \f(CW\*(C`as\*(C'\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 \f(CW\*(C`as\*(C'\fR no file names it attempts to read one input file -from the \f(CW\*(C`as\*(C'\fR standard input, which is normally your terminal. You -may have to type \fBctl-D\fR to tell \f(CW\*(C`as\*(C'\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, \f(CW\*(C`as\*(C'\fR produces a small, empty object -file. -.PP -\&\f(CW\*(C`as\*(C'\fR may write warnings and error messages to the standard error -file (usually your terminal). This should not happen when a compiler -runs \f(CW\*(C`as\*(C'\fR automatically. Warnings report an assumption made so -that \f(CW\*(C`as\*(C'\fR could keep assembling a flawed program; errors report a -grave problem that stops the assembly. -.PP -If you are invoking \f(CW\*(C`as\*(C'\fR via the \s-1GNU\s0 C compiler (version 2), -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 -This passes two options to the assembler: \fB\-alh\fR (emit a listing to -standard output with 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 "\f(CW\*(C`\-a[cdhlmns]\*(C'\fR" 4 -.IX Item "-a[cdhlmns]" -Turn on listings, in any of a variety of ways: -.RS 4 -.Ip "\f(CW\*(C`\-ac\*(C'\fR" 4 -.IX Item "-ac" -omit false conditionals -.Ip "\f(CW\*(C`\-ad\*(C'\fR" 4 -.IX Item "-ad" -omit debugging directives -.Ip "\f(CW\*(C`\-ah\*(C'\fR" 4 -.IX Item "-ah" -include high-level source -.Ip "\f(CW\*(C`\-al\*(C'\fR" 4 -.IX Item "-al" -include assembly -.Ip "\f(CW\*(C`\-am\*(C'\fR" 4 -.IX Item "-am" -include macro expansions -.Ip "\f(CW\*(C`\-an\*(C'\fR" 4 -.IX Item "-an" -omit forms processing -.Ip "\f(CW\*(C`\-as\*(C'\fR" 4 -.IX Item "-as" -include symbols -.Ip "\f(CW\*(C`=file\*(C'\fR" 4 -.IX Item "=file" -set the name of the listing file -.RE -.RS 4 -.Sp -You may combine these options; for example, use \fB\-aln\fR for assembly -listing without forms processing.
