Nelson Chu bd0cf5a6ba RISC-V: Support the ISA-dependent CSR checking.
According to the riscv privilege spec, some CSR are only valid when rv32 or
the specific extension is set.  We extend the DECLARE_CSR and DECLARE_CSR_ALIAS
to record more informaton we need, and then check whether the CSR is valid
according to these information.  We report warning message when the CSR is
invalid, so we have a choice between error and warning by --fatal-warnings
option.  Also, a --no-warn/-W option is used to turn the warnings off, if
people don't want the warnings.

	gas/
	* config/tc-riscv.c (enum riscv_csr_class): New enum.  Used to decide
	whether or not this CSR is legal in the current ISA string.
	(struct riscv_csr_extra): New structure to hold all extra information
	of CSR.
	(riscv_init_csr_hash): New function.  According to the DECLARE_CSR and
	DECLARE_CSR_ALIAS, insert CSR extra information into csr_extra_hash.
	Call hash_reg_name to insert CSR address into reg_names_hash.
	(md_begin): Call riscv_init_csr_hashes for each DECLARE_CSR.
	(reg_csr_lookup_internal, riscv_csr_class_check): New functions.
	Decide whether the CSR is valid according to the csr_extra_hash.
	(init_opcode_hash): Update 'if (hash_error != NULL)' as hash_error is
	not a boolean.  This is same as riscv_init_csr_hash, so keep the
	consistent usage.

	* testsuite/gas/riscv/csr-dw-regnums.d: Add -march=rv32if option.
	* testsuite/gas/riscv/priv-reg.d: Add f-ext by -march option.
	* testsuite/gas/riscv/priv-reg-fail-fext.d: New testcase.  The source
	file is `priv-reg.s`, and the ISA is rv32i without f-ext, so the
	f-ext CSR are not allowed.
	* testsuite/gas/riscv/priv-reg-fail-fext.l: Likewise.
	* testsuite/gas/riscv/priv-reg-fail-rv32-only.d: New testcase.  The
	source file is `priv-reg.s`, and the ISA is rv64if, so the
	rv32-only CSR are not allowed.
	* testsuite/gas/riscv/priv-reg-fail-rv32-only.l: Likewise.

	include/
	* opcode/riscv-opc.h: Extend DECLARE_CSR and DECLARE_CSR_ALIAS to
	record riscv_csr_class.

	opcodes/
	* riscv-dis.c (print_insn_args): Updated since the DECLARE_CSR is changed.

	gdb/
	* riscv-tdep.c: Updated since the DECLARE_CSR is changed.
	* riscv-tdep.h: Likewise.
	* features/riscv/rebuild-csr-xml.sh: Generate the 64bit-csr.xml without
	rv32-only CSR.
	* features/riscv/64bit-csr.xml: Regernated.

	binutils/
	* dwarf.c: Updated since the DECLARE_CSR is changed.

		   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.
