I am not sure whether it is reasonable to change the order the comment.

I am prefer to keep the original order 
 
    // Map the global address operand to be a reference to the TOC entry we
    // will synthesize later. 'TOCEntry' is a label used to reference the
    // storage allocated in the TOC which contains the address of 'MOSymbol'.
      // If the symbol does not have the toc-data attribute, then we create the
    // TOC entry on AIX. If the toc-data attribute is used, the TOC entry
    // contains the data rather than the address of the MOSymbol.
    
but feel free to keep your comment if you think it is reasonable,
