|
<p>Every time you run <code>as</code> it produces an output file, which is
|
||
|
|
your assembly language program translated into numbers. This file
|
||
|
|
is the object file. Its default name is
|
||
|
|
<code>a.out</code>.
|
||
|
|
You can give it another name by using the <samp>-o</samp> option. Conventionally,
|
||
|
|
object file names end with <samp>.o</samp>. The default name is used for historical
|
||
|
|
reasons: older assemblers were capable of assembling self-contained programs
|
||
|
|
directly into a runnable program. (For some formats, this isn’t currently
|
||
|
|
possible, but it can be done for the <code>a.out</code> format.)

<a name="index-linker"></a>
|
||
|
|
<a name="index-ld"></a>
|
||
|
|
<p>The object file is meant for input to the linker <code>ld</code>. It contains
|
||
|
|
assembled program code, information to help <code>ld</code> integrate
|
||
|
|
the assembled program into a runnable file, and (optionally) symbolic
|
||
|
|
information for the debugger.
