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
