GCNRegPressure llvm::max (const GCNRegPressure &P1, const GCNRegPressure &P2)
 
LaneBitmask llvm::getLiveLaneMask (unsigned Reg, SlotIndex SI, const LiveIntervals &LIS, const MachineRegisterInfo &MRI)

template<typename Range >
DenseMap< MachineInstr *, GCNRPTracker::LiveRegSet > llvm::getLiveRegMap (Range &&R, bool After, LiveIntervals &LIS)
 creates a map MachineInstr -> LiveRegSet R - range of iterators on instructions After - upon entry or exit of every instruction Note: there is no entry in the map for instructions with empty live reg set Complexity = O(NumVirtRegs * averageLiveRangeSegmentsPerReg * lg(R)) More...
