Andrew Burgess 0dbfcfffe9 gdb/riscv: Fix register access for register aliases
Some confusion over how the register names and aliases are setup in
riscv means that we currently can't access registers through their
architectural name.

This commit fixes this issue, and moves some of the csr register
handling out of the alias handling code and deals with it separately.
This has the benefit that we can now directly access some arrays
rather than having to iterate over them.

A new test is added to ensure that register aliases now work
correctly.

gdb/ChangeLog:

	* riscv-tdep.c (riscv_gdb_reg_names): Update comment, and all
	register names.
	(struct register_alias): Rename to...
	(struct riscv_register_alias): ...this, and update comment.
	(riscv_register_aliases): Update type, and alias names.  Remove
	CSR names from this list.
	(riscv_register_name): Use riscv_gdb_reg_names for int and float
	register names.  Add an extra assertion.
	(riscv_is_regnum_a_named_csr): New function.
	(riscv_register_reggroup_p): Use riscv_is_regnum_a_named_csr.

gdb/testsuite/ChangeLog:

	* gdb.arch/riscv-reg-aliases.c: New file.
	* gdb.arch/riscv-reg-aliases.exp: New file.

		   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.
