I agree that the insn is invalid. It probably should be something like this:
(parallel [
(set (reg:PSI 7 fb)
(mem:PSI (reg:PSI 7 fb) [0 S4 A8]))
(set (reg:PSI 8 sp)
(plus:PSI (reg:PSI 7 fb)
(const_int 2 [0x2])))
(return)
])
I.e. one set of sp and fb each. The faulty pattern is named "epilogue_exitd".
The two patterns "prologue_enter_16" and "prologue_enter_24" are also broken in
that they use
(parallel [
... (pre_dec (SP_REGNO))
(set (SP_REGNO) ...)
])
which is just another invalid use of PARALLEL. DJ?
On the AVR, my bets are on the define_insn "call_prologue_saves" with two sets
of (reg:HI SP_REG) inside the implicit parallel.
