   The D30V version of `as' uses the instruction names in the D30V
Architecture Manual.  However, the names in the manual are sometimes
ambiguous.  There are instruction names that can assemble to a short or
long form opcode.  How does the assembler pick the correct form?  `as'
will always pick the smallest form if it can.  When dealing with a
symbol that is not defined yet when a line is being assembled, it will
always use the long form.  If you need to force the assembler to use
either the short or long form of the instruction, you can append either
`.s' (short) or `.l' (long) to it.  For example, if you are writing an
assembly program and you want to do a branch to a symbol that is
defined later in your program, you can write `bra.s foo'.  Objdump and
GDB will always append `.s' or `.l' to instructions which have both
short and long forms.
