bfd/ 2020-01-22 Maxim Blinov <maxim.blinov@embecosm.com> * bfd/elfnn-riscv.c (riscv_skip_prefix): New. (riscv_prefix_cmp): Likewise. (riscv_non_std_ext_p): Deleted. (riscv_std_sv_ext_p): Likewise. (riscv_non_std_sv_ext_p): Likewise. (riscv_merge_non_std_and_sv_ext): Rename to... (riscv_merge_multi_letter_ext): and modified to use riscv_prefix_cmp. (riscv_merge_arch_attr_info): Replace 3 calls to riscv_merge_non_std_and_sv_ext with single call to riscv_merge_multi_letter_ext. * bfd/elfxx-riscv.c (riscv_parse_std_ext): Break if we encounter a 'z' prefix. (riscv_get_prefix_class): New function, return prefix class based on first few characters of input string. (riscv_parse_config): New structure to factor out minor differences in extension class parsing behaviour. (riscv_parse_sv_or_non_std_ext): Rename to... (riscv_parse_prefixed_ext): and parameterise with riscv_parse_config. (riscv_std_z_ext_strtab, riscv_std_s_ext_strtab): New. (riscv_multi_letter_ext_valid_p): New. (riscv_ext_x_valid_p, riscv_ext_z_valid_p, riscv_ext_s_valid_p): New. (riscv_parse_subset): Delegate all non-single-letter parsing work to riscv_parse_prefixed_ext. * bfd/elfxx-riscv.h (riscv_isa_ext_class): New type. (riscv_get_prefix_class): Declare. gas/ 2020-01-22 Maxim Blinov <maxim.blinov@embecosm.com> * testsuite/gas/riscv/march-ok-s.d: sx is no longer valid and s exts must be known, so rename *ok* to *fail*. * testsuite/gas/riscv/march-ok-sx.d: Likewise. * testsuite/gas/riscv/march-ok-s-with-version: Likewise. * testsuite/gas/riscv/march-fail-s.l: Expected error messages for above change. * testsuite/gas/riscv/march-fail-sx.l: Likewise. * testsuite/gas/riscv/march-fail-sx-with-version.l: Likewise.
