Christoph Müllner fb1737381d RISC-V: Add generic support for vendor extensions
This patch introduces changes that allow the integration of vendor ISA
extensions:
* Define a list of vendor extensions (riscv_supported_vendor_x_ext)
  where vendor extensions can be added
* Introduce a section with a table in the documentation where vendor
  extensions can be added

To add a vendor extension that consists of instructions only,
the following things need to be done:
* Add the extension to the riscv_supported_vendor_x_ext list
* Add lookup entry in riscv_multi_subset_supports
* Documenting the extension in c-riscv.texti
* Add test cases for all instructions
* Add MATCH*/MASK* constants and DECLARE_INSN() for all instructions
* Add new instruction class to enum riscv_insn_class
* Define the instructions in riscv_opcodes
* Additional changes if necessary (depending on the instructions)

		   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.
