Nelson Chu c625f4ed05 RISC-V: Use single h extension to control hypervisor CSRs and instructions.
According to the picture 28.1 in the current ISA spec, h is no larger the
multi-letter extension, it is a single extension after v.  Therefore, this
patch fix the implementation, and use the single h to control hypervisor
CSRs and instructions, which we promised to do before.

bfd/

    (riscv_supported_std_h_ext): Removed.
    (riscv_all_supported_ext): Updated since riscv_supported_std_h_ext is removed.
    (riscv_prefix_ext_class): Removed RV_ISA_CLASS_H.
    (parse_config): Updated since riscv_prefix_ext_class is removed.
    (riscv_recognized_prefixed_ext): Likewise.
    (riscv_get_default_ext_version): Likewise.
    (riscv_multi_subset_supports): Handle INSN_CLASS_H for hypervisor instructions.
    (riscv_multi_subset_supports_ext): Likewise.
gas/
    * config/tc-riscv.c (riscv_csr_class): Added CSR_CLASS_H and CSR_CLASS_H_32 for
    hypervisor CSRs.
    (riscv_csr_address): Likewise.
    * testsuite/gas/riscv/csr-version-1p10.d: Updated since hypervisor CSRs are
    controlled by single h extension for now.
    * testsuite/gas/riscv/csr-version-1p10.l: Likewise.
    * testsuite/gas/riscv/csr-version-1p11.d: Likewise.
    * testsuite/gas/riscv/csr-version-1p11.l: Likewise.
    * testsuite/gas/riscv/csr-version-1p12.d: Likewise.
    * testsuite/gas/riscv/csr-version-1p12.l: Likewise.
    * testsuite/gas/riscv/csr-version-1p9p1.d: Likewise.
    * testsuite/gas/riscv/csr-version-1p9p1.l: Likewise.
    * testsuite/gas/riscv/h-ext-32.d: Added h to architecture string.
    * testsuite/gas/riscv/h-ext-64.d: Likewise.
    * testsuite/gas/riscv/march-fail-single-prefix-h: Removed since h is no
    longer multi-letter extension.
    * testsuite/gas/riscv/march-fail-unknown-h.d: Likewise.
include/
    * opcode/riscv-opc.h: Control hypervisor CSRs by h extension, rather than
    the privileged spec verisons.
    * opcode/riscv.h (riscv_insn_class): Added INSN_CLASS_H.
opcodes/
    * riscv-opc.c (riscv_opcodes): Control hypervisor instructions by h extension.

		   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.
