 9.10.2.3 Special Characters
 ...........................
 
 A semicolon (';') can be used anywhere on a line to start a comment that
 extends to the end of the line.
 
    If a '#' appears as the first character of a line, the whole line is
 treated as a comment, but in this case the line could also be a logical
 line number directive (Comments) or a preprocessor control
 command (Preprocessing).
 
    Sub-instructions may be executed in order, in reverse-order, or in
 parallel.  Instructions listed in the standard one-per-line format will
 be executed sequentially.  To specify the executing order, use the
 following symbols:
 '->'
      Sequential with instruction on the left first.
 '<-'
      Sequential with instruction on the right first.
 '||'
      Parallel
    The D10V syntax allows either one instruction per line, one
 instruction per line with the execution symbol, or two instructions per
 line.  For example
 'abs a1 -> abs r0'
      Execute these sequentially.  The instruction on the right is in the
      right container and is executed second.
 'abs r0 <- abs a1'
      Execute these reverse-sequentially.  The instruction on the right
      is in the right container, and is executed first.
 'ld2w r2,@r8+ || mac a0,r0,r7'
      Execute these in parallel.
 'ld2w r2,@r8+ ||'
 'mac a0,r0,r7'
      Two-line format.  Execute these in parallel.
 'ld2w r2,@r8+'
 'mac a0,r0,r7'
      Two-line format.  Execute these sequentially.  Assembler will put
      them in the proper containers.
 'ld2w r2,@r8+ ->'
 'mac a0,r0,r7'
      Two-line format.  Execute these sequentially.  Same as above but
      second instruction will always go into right container.
    Since '$' has no special meaning, you may use it in symbol names.
