...rmation which is not normally reachable through the MCSchedModel interface. For example, predicate code coud use the TargetInstrInfo interface to obtain extra description for MachineInst objects. This is what happens for ARM targets, where the `PredicateProlog` casts the TargetInstrInfo object to a ARMBaseInstInfo, and predicated use the ARMBaseInstrInfo interface. Some predicates defined by the cortex-a9 scheduling model select the scheduling class "based on the number of memory addresses in the LDM MachineInstr". Emulating that query would require extra knowledge on the machine memory operands, w...
