Hi, This patch is to move rs6000_vect_nonmem (target cost_data related information) into target cost_data struct. Following Richi's comments in the thread[1], we can gather data from add_stmt_cost invocations. This is one pre-step to centralize target cost_data related stuffs.
Is it ok for trunk? BR, Kewen [1] https://gcc.gnu.org/pipermail/gcc-patches/2021-May/569836.html ----- gcc/ChangeLog: * config/rs6000/rs6000.c (rs6000_vect_nonmem): Renamed to vect_nonmem and moved into... (struct rs6000_cost_data): ...here. (rs6000_init_cost): Use vect_nonmem of cost_data instead. (rs6000_add_stmt_cost): Likewise. (rs6000_finish_cost): Likewise.
