(http://gcc.gnu.org/ml/gcc-patches/2011-04/msg01309.html) It contains a minor change from the previous submission suggested by Richard Sandiford: to use reg_referenced_p instead of rtx_referenced_p. The patch supports instructions with auto inc/dec operations as to support such instructions we can not assume that there is only one definition in the instruction. This assumption is currently used to generate reg-moves information. Because the auto inc/dec instruction defines more then one register we need to generate different reg-moves for each of the definitions. At some point in the SMS procedure we need to find the first reg-move generated for a specific definition(*) and if there is more than one definition in the instruction (lets call it insn1) we can not simply assume it's first reg-move instruction is the first instruction right before insn1. for example, the following instruction defines two variables: x and i: x = mem [POST_INC (i)] lets say both of them need reg-move insn 1) reg_move_i = i insn 2) reg_move_x = x insn 3) x = mem [POST_INC (i)] then in order to reach the first reg-move of i we can not just go to insn 2 like in the current implementation, so we need to save for each definition in the instruction it's first reg-move instruction. (*) I'm referring to the generation of prologue and epilogue (duplicate_insns_of_cycles) which uses first_reg_move field in node_sched_params structure, and SCHED_FIRST_REG_MOVE definition in modulo-sched.c. Reg-tested and bootstrap on ppc64-redhat-linux enabling SMS on loops with SC 1. OK for mainline? Thanks, Revital * modulo-sched.c (record_inc_dec_insn_info, free_node_sched_params): New functions. (SCHED_FIRST_REG_MOVE, SCHED_NREG_MOVES): Remove. (struct regmove_info): New. (insn_regmove_info): New field in node_sched_params. (print_node_sched_params): Print information for all the definitions in the instructions. (generate_reg_moves, duplicate_insns_of_cycles, set_node_sched_params): Adjust the code to handle instructions that have multiple definitions. (sms_schedule): Handle loops that contain instructions with FIND_REG_INC_NOTE and call free_node_sched_params.
