Changes: There was a condition for `!NeedsFrameRecord` missing in the assert. The assert in question has changed to: + assert((!RPI.isPaired() || !NeedsFrameRecord || RPI.Reg2 != AArch64::FP || + RPI.Reg1 == AArch64::LR) && + "FrameRecord must be allocated together with LR"); This addresses PR43016. llvm-svn: 369122
