...f FFI->hasCalls() is true. The only place where MachineFrameInfo::setHasCalls is invoked is PEI::saveCallerSavedRegisters and the value 'true' is only passed when there are instructions with opcodes equal to either RegInfo->getCallFrameSetupOpcode() or RegInfo->getCallFrameDestroyOpcode(). I don't have such special opcode, so hasCalls returns false and the stack is not aligned. Any ideas? - Volodya

...| Destroy2---->PredSU <----SU ^ ^ ^ | | | | | | ----------- | --------- | | | Destroy1 ^ | In this example there are two successors of 'PredSU' with type getCallFrameDestroyOpcode (Destroy) and one is a successor of the other. Taking the successor of the two Destroys (Destroy1), noted that it's matching getCallFrameSetupOpcode (Setup1) is a predecessor of 'SU'. In this situation, re-routing the dependency on 'PredSU' through 'SU' will cause a...

Here is a bit more data. After PrescheduleNodesWithMultipleUses has been run, the following Predecessor/Successor links are 'dumpAll'ed. (I attach the full dumpAll before & after "Prescheduling SU #7 next to PredSU #4 to guide scheduling in the presence of multiple uses") SU(3) Predecessors: val SU(5): Latency=1 ch SU(7): Latency=1 val SU(7): Latency=1 SU(7):

Hi, I have an assert firing due to PickNodeToScheduleBottomUp(): 1. having a CallResource in use pushing an interference of current SUnit. 2. having no more SUnits in the AvailableQueue 3. The only interference being the SUnit that just failed due to a Call Resource. 4. An attempt to duplicate this node which has the 'Call Resource' as a physical register. Thus the call
