There are two problems here:
1. The immediate problem is that "movsi_m68k" doesn't allow (const) to be moved
to data register (see last alternative if movsi_m68k).
2. For reason, which I have not yet investigated, no alternative in
"addsi_internal" match
(set (reg) (plus (reg %a5) (const (unspec))))
Andreas, do you know why movsi_m68k doesn't allow data register in the last
alternative?
(define_insn "*movsi_m68k"
[(set (match_operand:SI 0 "nonimmediate_operand" "=g,d,a<")
(match_operand:SI 1 "general_src_operand" "damSnT,n,i"))]
