SH64 Machine Directives
-----------------------

   In addition to the SH directives, the SH64 provides the following
directives:

`.mode [shmedia|shcompact]'
`.isa [shmedia|shcompact]'
     Specify the ISA for the following instructions (the two directives
     are equivalent).  Note that programs such as `objdump' rely on
     symbolic labels to determine when such mode switches occur (by
     checking the least significant bit of the label's address), so
     such mode/isa changes should always be followed by a label (in
     practice, this is true anyway).  Note that you cannot use these
     directives if you didn't specify an ISA on the command line.

`.abi [32|64]'
     Specify the ABI for the following instructions.  Note that you
     cannot use this directive unless you specified an ABI on the
     command line, and the ABIs specified must match.

`.uaquad'
     Like .uaword and .ualong, this allows you to specify an
     intenionally unaligned quadword (64 bit word).
