For some reason, memory operand is prohibited in a sibcall, see predicates.md:
;; Test for a valid operand for a call instruction.
(define_predicate "call_insn_operand"
(ior (match_operand 0 "constant_call_address_operand")
(match_operand 0 "call_register_no_elim_operand")
(match_operand 0 "memory_operand")))
;; Similarly, but for tail calls, in which we cannot allow memory references.
(define_predicate "sibcall_insn_operand"
(ior (match_operand 0 "constant_call_address_operand")
(match_operand 0 "register_no_elim_operand")))
