| <dd><a name="index-_002dmcpu-command-line-option_002c-Alpha"></a> |
| </dd> |
| <dt><code>-m<var>cpu</var></code></dt> |
| <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. |

| </dd> |
| <dt><code>-mdebug</code></dt> |
| <dt><code>-no-mdebug</code></dt> |
| <dd><p>Enables or disables the generation of <code>.mdebug</code> encapsulation for |
| 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-_002drelax-command-line-option_002c-Alpha"></a> |
| </dd> |
| <dt><code>-relax</code></dt> |
| <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. |

| </dd> |
| <dt><code>-replace</code></dt> |
| <dt><code>-noreplace</code></dt> |
| <dd><p>Enables or disables the optimization of procedure calls, both at assemblage |
| 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. |
| </p> |
| <a name="index-_002dg-command-line-option_002c-Alpha"></a> |
| </dd> |
| <dt><code>-g</code></dt> |
| <dd><p>This option is used when the compiler generates debug information. When |
| <code>gcc</code> is using <code>mips-tfile</code> to generate debug |
| information for ECOFF, local labels must be passed through to the object |
| file. Otherwise this option has no effect. |

| <a name="index-_002dG-command-line-option_002c-Alpha"></a> |
| </dd> |
| <dt><code>-G<var>size</var></code></dt> |
| <dd><p>A local common symbol larger than <var>size</var> is placed in <code>.bss</code>, |
| while smaller symbols are placed in <code>.sbss</code>. |
