<p><a name="index-object-file-34"></a><a name="index-output-file-35"></a><a name="index-a_002eout-36"></a><a name="index-_002eo-37"></a>Every time you run <span class="command">as</span> 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 <span class="option">-o</span> option. Conventionally,
|
|
object file names end with <span class="file">.o</span>. 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.)
|
|
|
|
<p><a name="index-linker-38"></a><a name="index-ld-39"></a>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.
