| bool | llvm::constrainSelectedInstRegOperands (MachineInstr &I, const TargetInstrInfo &TII, const TargetRegisterInfo &TRI, const RegisterBankInfo &RBI) |
| | Mutate the newly-selected instruction I to constrain its (possibly generic) virtual register operands to the instruction's register class. More...
|
| |
| bool | llvm::isTriviallyDead (const MachineInstr &MI, const MachineRegisterInfo &MRI) |
| | Check whether an instruction MI is dead: it only defines dead virtual registers, and doesn't have other side effects. More...
