Thanks for a prompt reply, Nathan.
The add insn can take a symbol_ref, which is converted
to const_int during relocation. But I don't want to
allow expressions like (const:SI (plus:SI
symbol_ref:SI) (const_int)) in the insn.
How should I do that, do I need to implement
LEGITIMATE_CONST_P () accordingly?
thanks.
