<dd><p>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>
|
|
<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>
|
|
<p>In order to support existing practice in OSF/1 with respect to <code>.arch</code>,
|
|
and existing practice within <code>MILO</code> (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.

<dd><p>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.

<code>-replace</code> is the default. See section 1.4.1 of the OpenVMS Linker

information for ECOFF, local labels must be passed through to the object

file. Otherwise this option has no effect.
