◆ switchTo()

void llvm::RegBankSelect::RepairingPlacement::switchTo ( RepairingKind  NewKind)
inline

Change the type of this repairing placement to NewKind.

It is not possible to switch a repairing placement to the RepairingKind::Insert. There is no fundamental problem with that, but no uses as well, so do not support it for now.

Precondition
NewKind != RepairingKind::Insert
Postcondition
getKind() == NewKind
