* Two add subset functions is redundant. Keep the riscv_add_implicit_subset, and renamed it to riscv_add_subset. Besides, if the subset is added in order, then we just add it at the tail of the subset list. * Removed the "-march:" prefix from the error messages. Since not only the -march= option will use the parser, but also the architecture elf attributes, the default architecture setting and linker will use the same parser. * Use a function, riscv_parse_check_conflicts, to check the conflicts of extensions, including the rv64e and rv32q. The rv32emc-elf/rv32i-elf/rv32gc-linux/rv64gc-elf/rv64gc-linux regressions are tested and passed. bfd/ * elfxx-riscv.c (riscv_lookup_subset): Check the subset tail list first. If the subset is added in order, then we can just add it to the tail without searching the whole list. (riscv_add_subset): Replaced by riscv_add_implicit_subset. (riscv_add_implicit_subset): Renamed to riscv_add_subset. (riscv_parse_add_subset): Updated. (riscv_parsing_subset_version): Removed the "-march:" prefix from the error message. (riscv_parse_prefixed_ext): Likewise. (riscv_parse_std_ext): Likewise. And move the rv<xlen>e check to riscv_parse_check_conflicts. (riscv_parse_check_conflicts): New function used to check conflicts. (riscv_parse_subset): Updated. gas/ * testsuite/gas/riscv/march-fail-base-02.l: Updated. * testsuite/gas/riscv/march-fail-unknown-std.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.
