<dl><dt><code>-m</code><var>cpu</var><dd>This option specifies the target processor. If an attempt is made to
|
|
assemble an instruction which will not execute on the target processor,
|
|
the assembler may either expand the instruction as a macro or issue an
|
|
error message. This option is equivalent to the <code>.arch</code> directive.
|
|
|
|
<p>The following processor names are recognized:
|
|
<code>21064</code>,
|
|
<code>21064a</code>,
|
|
<code>21066</code>,
|
|
<code>21068</code>,
|
|
<code>21164</code>,
|
|
<code>21164a</code>,
|
|
<code>21164pc</code>,
|
|
<code>21264</code>,
|
|
<code>21264a</code>,
|
|
<code>21264b</code>,
|
|
<code>ev4</code>,
|
|
<code>ev5</code>,
|
|
<code>lca45</code>,
|
|
<code>ev5</code>,
|
|
<code>ev56</code>,
|
|
<code>pca56</code>,
|
|
<code>ev6</code>,
|
|
<code>ev67</code>,
|
|
<code>ev68</code>.
|
|
The special name <code>all</code> may be used to allow the assembler to accept
|
|
instructions valid for any Alpha processor.
|
|
|
|
<p>In order to support existing practice in OSF/1 with respect to <code>.arch</code>,
|
|
and existing practice within <samp><span class="command">MILO</span></samp> (the Linux ARC bootloader), the
|
|
numbered processor names (e.g. 21064) enable the processor-specific PALcode
|
|
instructions, while the “electro-vlasic” names (e.g. <code>ev4</code>) do not.

|
|
stabs directives and procedure descriptors. The default is to automatically
|
|
enable <code>.mdebug</code> when the first stabs directive is seen.
|
|

<p><a name="index-g_t_0040code_007b_002drelax_007d-command_002dline-option_002c-Alpha-596"></a><br><dt><code>-relax</code><dd>This option forces all relocations to be put into the object file, instead
|
|
of saving space and resolving some relocations at assembly time. Note that
|
|
this option does not propagate all symbol arithmetic into the object file,
|
|
because not all symbol arithmetic can be represented. However, the option
|
|
can still be useful in specific applications.

|
|
and at link time. These options are only available for VMS targets and
|
|
<code>-replace</code> is the default. See section 1.4.1 of the OpenVMS Linker
|
|
Utility Manual.

|
|
<samp><span class="command">gcc</span></samp> is using <samp><span class="command">mips-tfile</span></samp> to generate debug
|
|
information for ECOFF, local labels must be passed through to the object
|
|
file. Otherwise this option has no effect.
