After some exploration, I don't see that another approach is even possible. The predicates in define_insn_reservation must be statically evaluated by genattrtab, so I can't use (match_test "...") or (symbol_ref "..."), where "..." is arbitrary C code. Is it true that define_insn_reservation predicates can only use boolean expressions on (eq_attr ...), or am I missing something? G
