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 * testsuite/gas/riscv/march-ok-s.d: sx is no longer valid and s exts must be known, so rename *ok* to *fail*.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.

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
