9.8.2 Instruction expansion
---------------------------
'as' will silently choose an instruction that fits the operand size for
'[register+constant]' operands. For example, the offset '127' in
'move.d [r3+127],r4' fits in an instruction using a signed-byte offset.
Similarly, 'move.d [r2+32767],r1' will generate an instruction using a
16-bit offset. For symbolic expressions and constants that do not fit
in 16 bits including the sign bit, a 32-bit offset is generated.
For branches, 'as' will expand from a 16-bit branch instruction into
a sequence of instructions that can reach a full 32-bit address. Since
this does not correspond to a single instruction, such expansions can
optionally be warned about.

If the operand is found to fit the range, a 'lapc' mnemonic will
translate to a 'lapcq' instruction. Use 'lapc.d' to force the 32-bit
'lapc' instruction.
Similarly, the 'addo' mnemonic will translate to the shortest fitting
instruction of 'addoq', 'addo.w' and 'addo.d', when used with a operand
that is a constant known at assembly time.
