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).
