# The _rev suffix indicates that Vn and Vm are reversed. This is

# with the Vm and Vn fields in their usual places, but in the
# assembly the operands are listed "backwards", ie in the order
# Qd, Qm, Qn where other insns use Qd, Qn, Qm. For QEMU we choose
# to consider Vm and Vn as being in different fields in the insn.
# This gives us consistency with A64 and Neon.

# Logical immediate operations (1 reg and modified-immediate)
# The cmode/op bits here decode VORR/VBIC/VMOV/VMVN, but
# not in a way we can conveniently represent in decodetree without
# a lot of repetition:
# VORR: op=0, (cmode & 1) && cmode < 12
# VBIC: op=1, (cmode & 1) && cmode < 12
# VMOV: everything else
# So we have a single decode line and check the cmode/op in the
# trans function.
