Init the riscv_ext_order + according to the riscv_supported_std_ext and parse_config[i].class + automatically. + (riscv_compare_subsets): New function. Similar to the strcmp, but + compare the subsets with the specific order. + (riscv_lookup_subset): Return TRUE and set `current` to the subset + if it is found. Otherwise, return FALSE and set `current` to the + place where we should insert the subset. + (riscv_add_implicit_subset): New function. Search the list first, + and then find the right place to add the implicit_subset. + (riscv_parse_add_subset): Since We have to add all arch string + extensions first, and then start to add their implicit extensions. + We can add arch string extensions in order by the original + riscv_add_subset, and then add the implicit subsets by the + riscv_add_implicit_subset. Besides, do not add the implicit + extensions if we failed to find their default versions. + (riscv_parse_std_ext): Updated. + (riscv_parse_add_implicit_subsets): New function. Add all implicit + extensions according to the arch string extensions. + (riscv_parse_subset): Call riscv_init_ext_order and + riscv_parse_add_implicit_subsets, before and after parsing the + arch string. Remove parts of the ISA conflict checking since + the implicit extensions are added. + * elfxx-riscv.h (riscv_lookup_subset): Updated. + +2020-12-01 Nelson Chu <nelson.chu@sifive.com> + * elfxx-riscv.c (riscv_lookup_subset): Moved to front. (riscv_add_subset): Likewise. (riscv_release_subset_list): Likewise. |
