   For detailed information on the SH64 machine instruction set, see
`SuperH 64 bit RISC Series Architecture Manual' (SuperH, Inc.).

   `as' implements all the standard SH64 opcodes.  In addition, the
following pseudo-opcodes may be expanded into one or more alternate
opcodes:

`movi'
     If the value doesn't fit into a standard `movi' opcode, `as' will
     replace the `movi' with a sequence of `movi' and `shori' opcodes.

`pt'
     This expands to a sequence of `movi' and `shori' opcode, followed
     by a `ptrel' opcode, or to a `pta' or `ptb' opcode, depending on
     the label referenced.
