Hi all, I think there is a mistake in the machinepipeliner interface. In the TargetInstrInfo.h in the class PipelinerLoopInfo there is a function "bool shouldIgnoreForPipelining(const MachineInstr *MI)". The description says that if this function returns true for a given MachineInstr it will not be pipelined. However in reality it is not ignored and is being considered for

...ng. Hi Sander: It may be confusing, but it is not a bug. And you are right, if you are using the in-tree machinepipeliner, it won't have any effects, because there is NO In tree reference of this API at all.
