| static void | allocateHSAUserSGPRs (CCState &CCInfo, MachineIRBuilder &B, MachineFunction &MF, const SIRegisterInfo &TRI, SIMachineFunctionInfo &Info) |
| static std::pair< CCAssignFn *, CCAssignFn * > | getAssignFnsForCC (CallingConv::ID CC, const SITargetLowering &TLI) |
| Returns a pair containing the fixed CCAssignFn and the vararg CCAssignFn for CC. | |

| static bool | canGuaranteeTCO (CallingConv::ID CC) |
| Return true if the calling convention is one that we can guarantee TCO for. | |
| static bool | mayTailCallThisCC (CallingConv::ID CC) |
| Return true if we might ever do TCO for calls with this calling convention. | |
