Andrea Di Biagio c8095b709a [MCA][Scheduler] Collect resource pressure and memory dependency bottlenecks. ... Every cycle, the Scheduler checks if instructions in the ReadySet can be issued to the underlying pipelines. If an instruction cannot be issued because one or more pipeline resources are unavailable, then field Instruction::CriticalResourceMask is updated with the resource identifier of the unavailable resources. If an instruction cannot be promoted from the PendingSet to the ReadySet because of a memory dependency, then field Instruction::CriticalMemDep is updated with the identifier of the dependending memory instruction. Bottleneck information is collected after every cycle for instructions that are waiting to execute. The idea is to help identify causes of bottlenecks; this information can be used in future to implement a bottleneck analysis. llvm-svn: 354490		2019-02-20 18:01:49 +00:00
