 9.42.2.3 Addressing Modes
 .........................
 
 'as' understands the following addressing modes for the SH. 'RN' in the
 following refers to any of the numbered registers, but _not_ the control
 registers.
 
 'RN'
      Register direct
 
 '@RN'
      Register indirect
 
 '@-RN'
      Register indirect with pre-decrement
 
 '@RN+'
      Register indirect with post-increment
 
 '@(DISP, RN)'
      Register indirect with displacement
 
 '@(R0, RN)'
      Register indexed
 
 '@(DISP, GBR)'
      'GBR' offset
 
 '@(R0, GBR)'
      GBR indexed
 
 'ADDR'
 '@(DISP, PC)'
      PC relative address (for branch or for addressing memory).  The
      'as' implementation allows you to use the simpler form ADDR
      anywhere a PC relative address is called for; the alternate form is
      supported for compatibility with other assemblers.
 
 '#IMM'
      Immediate data
