| The first call to this method will cause the splitting to happen if need be, then sub sequent calls just return the iterator to that point. | |

| The first call to this method will cause the splitting to happen if need be, then sub sequent calls just return the basic block that contains the insertion point. | |

Insert MI in the just before getPoint() | |

inlineoverridevirtual |
Check whether this insertion point can be materialized.
As soon as getPoint is called and thus, the point materialized calling this method does not make sense.
Reimplemented from llvm::RegBankSelect::InsertPoint.
Definition at line 233 of file RegBankSelect.h.
◆ frequency()
Frequency of the insertion point.
P is used to access the various analysis that will help to get that information, like MachineBlockFrequencyInfo. If P does not contain enough to return the actual frequency, this returns 1.
Reimplemented from llvm::RegBankSelect::InsertPoint.
Definition at line 919 of file RegBankSelect.cpp.

◆ isSplit()

Does this point involve splitting an edge or block? As soon as getPoint is called and thus, the point materialized, the point will not require splitting anymore, i.e., this will return false.
