--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Yes, it does (just verified with latest trunk). ;; TImode/PTImode is similar, except that we usually want to compute the ;; address into a register and use lsi/stsi (the exception is during reload). (define_insn "*mov<mode>_string" [(set (match_operand:TI2 0 "reg_or_mem_operand" "=Q,Y,????r,????r,????r,r") (match_operand:TI2 1 "input_operand" "r,r,Q,Y,r,n"))] "! TARGET_POWERPC64 && (<MODE>mode != TImode || VECTOR_MEM_NONE_P (TImode)) && (gpc_reg_operand (operands[0], <MODE>mode) || gpc_reg_operand (operands[1], <MODE>mode))" "#" [(set_attr "type" "store,store,load,load,*,*") (set_attr "update" "yes") (set_attr "indexed" "yes") (set_attr "cell_micro" "conditional")]) pattern is still there.
