Namespaces
namespace	llvm
	This is an optimization pass for GlobalISel generic memory operations.

Typedefs
using	llvm::ShouldSchedulePredTy = std::function< bool(const TargetInstrInfo &TII, const TargetSubtargetInfo &TSI, const MachineInstr *FirstMI, const MachineInstr &SecondMI)>
	Check if the instr pair, FirstMI and SecondMI, should be fused together.

Functions
bool	llvm::hasLessThanNumFused (const SUnit &SU, unsigned FuseLimit)
	Checks if the number of cluster edges between SU and its predecessors is less than FuseLimit.
bool	llvm::fuseInstructionPair (ScheduleDAGInstrs &DAG, SUnit &FirstSU, SUnit &SecondSU)
	Create an artificial edge between FirstSU and SecondSU.
std::unique_ptr< ScheduleDAGMutation >	llvm::createMacroFusionDAGMutation (ShouldSchedulePredTy shouldScheduleAdjacent)
	Create a DAG scheduling mutation to pair instructions back to back for instructions that benefit according to the target-specific shouldScheduleAdjacent predicate function.
std::unique_ptr< ScheduleDAGMutation >	llvm::createBranchMacroFusionDAGMutation (ShouldSchedulePredTy shouldScheduleAdjacent)
	Create a DAG scheduling mutation to pair branch instructions with one of their predecessors back to back for instructions that benefit according to the target-specific shouldScheduleAdjacent predicate function.
