[llvm-dev] MIR instruction size

Hello,
Is there any common way to determine a size of MIR instruction? I've tried
both: MachineInstr::getDesc().getSize() and
TargetInstrInfo::getInstSizeInBytes(I),
and unfortunately, both interfaces can't determine instruction sizes for
x86_64, though they could do it for arm architecture.
