Nelson Chu aed44286ef RISC-V: Updated the default ISA spec to 20191213.
Update the default ISA spec from 2.2 to 20191213 will change the default
version of i from 2.0 to 2.1.  Since zicsr and zifencei are separated
from i 2.1, users need to add them in the architecture string if they need
fence.i and csr instructions.  Besides, we also allow old ISA spec can
recognize zicsr and zifencei, but we won't output them since they are
already included in the i extension when i's version is less than 2.1.

bfd/
	* elfxx-riscv.c (riscv_parse_add_subset): Allow old ISA spec can
	recognize zicsr and zifencei.
gas/
	* config/tc-riscv.c (DEFAULT_RISCV_ISA_SPEC): Updated to 20191213.
	* testsuite/gas/riscv/csr-version-1p10.d: Added zicsr to -march since
	the default version of i is 2.1.
	* testsuite/gas/riscv/csr-version-1p11.d: Likewise.
	* testsuite/gas/riscv/csr-version-1p12.d: Likewise.
	* testsuite/gas/riscv/csr-version-1p9p1.d: Likewise.
	* testsuite/gas/riscv/option-arch-03.d: Updated i's version to 2.1.
	* testsuite/gas/riscv/option-arch-03.s: Likewise.
ld/
	* testsuite/ld-riscv-elf/call-relax.d: Added zicsr to -march since
	the default version of i is 2.1.
	* testsuite/ld-riscv-elf/attr-merge-arch-01.d: Updated i's version to 2.1.
	* testsuite/ld-riscv-elf/attr-merge-arch-01a.s: Likewise.
	* testsuite/ld-riscv-elf/attr-merge-arch-01b.: Likewise.
	* testsuite/ld-riscv-elf/attr-merge-arch-02.d: Likewise.
	* testsuite/ld-riscv-elf/attr-merge-arch-02a.s: Likewise.
	* testsuite/ld-riscv-elf/attr-merge-arch-02b.s: Likewise.

	* testsuite/ld-riscv-elf/attr-merge-arch-03a.s: Likewise.
	* testsuite/ld-riscv-elf/attr-merge-arch-03b.s: Likewise.
	* testsuite/ld-riscv-elf/attr-merge-arch-failed-02.d: Added zifencei
	into Tag_RISCV_arch since it is added implied when i's version is
	larger than 2.1.

		   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.
