Macro insns aren't real insns, they map to one or more real insns.
E.g. An architecture's "nop" insn may actually be an "mv r0,r0" or
some such.
Macro insns can expand to nothing (e.g. a nop that is optimized away).
This is useful in multi-insn macros that build a constant in a register.
Of course this isn't the default behaviour and must be explicitly enabled.
Assembly of macro-insns is relatively straightforward. Disassembly isn't.
However, disassembly of at least some kinds of macro insns is important
in order that the disassembled code preserve the readability of the original
insn. What is attempted here is to disassemble all "simple" macro-insns,
where "simple" is currently defined to mean "expands to one real insn".
Simple macro-insns are handled specially. They are emitted as ALIAS's
of real insns. This simplifies their handling since there's usually more
of them than any other kind of macro-insn, and proper disassembly of them
falls out for free. */
