Entry opcode needs to check if moving to new register frame would cause register window overflow. Entry used in function prologue never overflows because preceding windowed call* opcode writes return address to the target register window frame, causing overflow exceptions at the point of call. But when a sequence of entry opcodes is used for register window spilling there may not be a call or other opcode that would cause window check between entries and they would not raise overflow exception themselves resulting in data corruption.
