...G and H. This can implemented by dividing the PEI pass into an analyze and an action pass. The analyze pass just calls calculateCallsInformation for each MachineFunction. After this, if we are compiling with split-stacks (i.e. the target supports it, and it is enabled), we run a CallGraphSCCPass (InferGlobalStackSpace, say) which implements the algorithm mentioned in the paper. The actual insertion of the prologue and epilogue code is delegated to a third pass. This (third) pass uses the data collected by InferGlobalStackSpace to insert appropriately modified prologues (the epilogue remains the same). Issues...
