--------------------------------
'as' has the following machine-dependent directives for the H8/300:
'.h8300h'
Recognize and emit additional instructions for the H8/300H variant,
and also make '.int' emit 32-bit numbers rather than the usual
(16-bit) for the H8/300 family.
'.h8300s'
Recognize and emit additional instructions for the H8S variant, and
also make '.int' emit 32-bit numbers rather than the usual (16-bit)
for the H8/300 family.
'.h8300hn'
Recognize and emit additional instructions for the H8/300H variant
in normal mode, and also make '.int' emit 32-bit numbers rather
than the usual (16-bit) for the H8/300 family.
'.h8300sn'
Recognize and emit additional instructions for the H8S variant in
normal mode, and also make '.int' emit 32-bit numbers rather than
the usual (16-bit) for the H8/300 family.
On the H8/300 family (including the H8/300H) '.word' directives
generate 16-bit numbers.
