================
Comment at: llvm/lib/Target/PowerPC/PPCFrameLowering.cpp:1326
+ // sp -= gap;
+ // When HasBP && isPPC64, we have r0, r1, r12, r30 available and r1 is already
+ // copied to r30 which is BPReg. So BPReg stores the value of back-chain

Should be `HasBP && HasRedzone`, I have updated the condition.
