// Generic Processor Scheduler Models.
// IssueWidth is analogous to the number of decode units. Core and its
// descendants, including Nehalem and SandyBridge have 4 decoders.
// Resources beyond the decoder operate on micro-ops and are buffered
// so adjacent micro-ops don't directly compete.
//
// MicroOpBufferSize > 1 indicates that RAW dependencies can be
// decoded in the same cycle. The value 32 is a reasonably arbitrary
// number of in-flight instructions.
//
// HighLatency=10 is optimistic. X86InstrInfo::isHighLatencyDef
// indicates high latency opcodes. Alternatively, InstrItinData
// entries may be included here to define specific operand
// latencies. Since these latencies are not used for pipeline hazards,
// they do not need to be exact.
//
// The GenericX86Model contains no instruction schedules
// and disables PostRAScheduler.
