Is there a particular reason why you're using target hooks rather than named patterns in the md file? This *is* happening during rtl expansion after all, when we're already well integrated with the backend. E.g. (define_expand "get_thread_pointer" [(set (match_operand:P 0 "...") (...))] ) (define_expand "set_thread_pointer" [(set (...) (match_operand:P 0 "..."))] ) r~
