Nelson Chu 437e2ff1ad RISC-V: Tidy riscv assembler and disassembler.
Tidy the gas/config/tc-riscv.c and opcodes/riscv-dis.c, to prepare for
moving the released extensions (including released vendor extensions)
from integration branch back to mainline.

* Added parts of missing comments.

* Updated md_show_usage.

* For validate_riscv_insn, riscv_ip and print_insn_args, unify the
  following pointer names,
  - oparg: pointed to the parsed operand defined in the riscv_opcodes.
  - asarg: pointed to the parsed operand from assembly.
  - opargStart: recorded the parsed operand name from riscv_opcodes.
  - asargStart: recorded the parsed operand name from assembly.

gas/
	* config/tc-riscv.c: Added parts of missind comments and updated
	the md_show_usage.
	(riscv_multi_subset_supports): Tidy codes.
	(validate_riscv_insn): Unify the pointer names, oparg, asarg,
	opargStart and asargStart, to prepare for moving the released
	extensions from integration branch back to mainline.
	(riscv_ip): Likewise.
	(macro_build): Added fmtStart, also used to prepare for moving
	released extensions.
	(md_show_usage): Added missing descriptions for new options.
opcodes/
	* riscv-dis.c (print_insn_args): Unify the pointer names,
	oparg and opargStart, to prepare for moving the released
	extensions from integration branch back to mainline.

		   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.
