<h3 class="section"><code>ld</code> and MMIX</h3>



   <p>For MMIX, there is choice of generating <code>ELF</code> object files or

<code>mmo</code> object files when linking.  The simulator <code>mmix</code>

understands the <code>mmo</code> format.  The binutils <code>objcopy</code> utility

can translate between the two formats.



   <p>There is one special section, the <code>.MMIX.reg_contents</code> section. 

Contents in this section is assumed to correspond to that of global

registers, and symbols referring to it are translated to special symbols,

equal to registers.  In a final link, the start address of the

<code>.MMIX.reg_contents</code> section corresponds to the first allocated

global register multiplied by 8.  Register <code>$255</code> is not included in

this section; it is always set to the program entry, which is at the

symbol <code>Main</code> for <code>mmo</code> files.



   <p>Symbols with the prefix <code>__.MMIX.start.</code>, for example

<code>__.MMIX.start..text</code> and <code>__.MMIX.start..data</code> are special;

there must be only one each, even if they are local.  The default linker

script uses these to set the default start address of a section.



   <p>Initial and trailing multiples of zero-valued 32-bit words in a section,

are left out from an mmo file.
