+#
+# - default : build all libraries and programs
+# - check : build and run all unit tests
+# - install : install headers, project library, and some programs
+# - clean : remove all generated content (except autoconf files)
+# - dist : make a source tarball
+# - distcheck : make a source tarball, untar it, check it, clean it
+# - distclean : remove everything
+#

+RISC-V ISA Simulator
+==========================================================================
+# Author : Andrew Waterman
+# Date : June 19, 2011
+# Version : (under version control)
+
+The RISC-V ISA Simulator implements a functional model of one or more
+RISC-V processors.
+
+--------------------------------------------------------------------------
+Build Steps
+--------------------------------------------------------------------------
+
+ % mkdir build
+ % cd build
+ % ../configure
+ % make
+ % [sudo] make install
+
+--------------------------------------------------------------------------
+Usage
+--------------------------------------------------------------------------
+
+The riscv-isa-run program is not usually invoked directly; rather, fesvr, the
+Front-End Server, invokes riscv-isa-run. fesvr and riscv-pk must be installed
+to simulate a RISC-V user program using riscv-isa-run.
+
+--------------------------------------------------------------------------
+Compiling and Running a Simple C Program
+--------------------------------------------------------------------------
+
+Install riscv-isa-run (see Build Steps), then install the following additional
+packages: riscv-fesvr, riscv-gcc, riscv-pk.
+
+Write a short C program and name it hello.c. Then, compile it into a RISC-V
+ELF binary named hello:
+
+ % riscv-gcc -o hello hello.c
+
+Now you can simulate the program:
+
+ % riscv-fesvr hello
+
+--------------------------------------------------------------------------
+Simulating a New Instruction
+--------------------------------------------------------------------------
+
+Adding an instruction to the simulator requires two steps:
+
+ 1. Describe the instruction's functional behavior in the file
+ riscv/insns/<new_instruction_name>.h. Examine other instructions
+ in that directory as a starting point.
+
+ 2. Add the instruction to the riscv-opcodes package:
+
+ % cd ../riscv-opcodes
+ % vi opcodes // add a line for the new instruction
+ % make install
+
+ 3. Rebuild the simulator.

+# Local Autoconf Macros
+#=========================================================================
+# This file contains the macros for the Modular C++ Build System and
+# additional autoconf macros which developers can use in their
+# configure.ac scripts. Please read the documentation in
+# 'mcppbs-doc.txt' for more details on how the Modular C++ Build System
+# works. The documenation for each macro should include information
+# about the author, date, and copyright.
+
+#-------------------------------------------------------------------------
+# MCPPBS_PROG_INSTALL
+#-------------------------------------------------------------------------
+# This macro will add an --enable-stow command line option to the
+# configure script. When enabled, this macro will first check to see if
+# the stow program is available and if so it will set the $stow shell
+# variable to the binary name and the $enable_stow shell variable to
+# "yes". These variables can be used in a makefile to conditionally use
+# stow for installation.
+#
+# This macro uses two environment variables to help setup default stow
+# locations. The $STOW_PREFIX is used for stowing native built packages.
+# The packages are staged in $STOW_PREFIX/pkgs and then symlinks are
+# created from within $STOW_PREFIX into the pkgs subdirectory. If you
+# only do native builds then this is all you need to set. If you don't
+# set $STOW_PREFIX then the default is just the normal default prefix
+# which is almost always /usr/local.
+#
+# For non-native builds we probably want to install the packages in a
+# different location which includes the host architecture name as part
+# of the prefix. For these kind of builds, we can specify the $STOW_ROOT
+# environment variable and the effective prefix will be
+# $STOW_ROOT/${host_alias} where ${host_alias} is specified on the
+# configure command line with "--host".
+#
+# Here is an example setup:
+#
+# STOW_ROOT="$HOME/install"

+# MCPPBS_SUBPROJECTS([ sproj1, sproj2, ... ])
+#-------------------------------------------------------------------------
+# The developer should call this macro with a list of the subprojects
+# which make up this project. One should order the list such that any
+# given subproject only depends on subprojects listed before it. The
+# subproject names can also include an * suffix which indicates that
+# this is an optional subproject. Optional subprojects are only included
+# as part of the project build if enabled on the configure command line
+# with a --enable-<subproject> flag. The user can also specify that all
+# optional subprojects should be included in the build with the
+# --enable-optional-subprojects flag.
+#
+# Subproject names can also include a ** suffix which indicates that it
+# is an optional subproject, but there is a group with the same name.
+# Thus the --enable-<sproj> command line option will enable not just the
+# subproject sproj but all of the subprojects which are in the group.
+# There is no error checking to make sure that if you use the ** suffix
+# you actually define a group so be careful.
+#
+# Both required and optional subprojects should have a 'subproject.ac'
+# file. The script's filename should be the abbreivated subproject name
+# (assuming the subproject name is sproj then we would use 'sproj.ac')
+# The MCPPBS_SUBPROJECTS macro includes the 'subproject.ac' files for
+# enabled subprojects. Whitespace and newlines are allowed within the

+\`configure' configures RISC-V ISA Simulator ? to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
+ --localstatedir=DIR modifiable single-machine data [PREFIX/var]
+ --libdir=DIR object code libraries [EPREFIX/lib]
+ --includedir=DIR C header files [PREFIX/include]
+ --oldincludedir=DIR C header files for non-gcc [/usr/include]
+ --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
+ --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
+ --infodir=DIR info documentation [DATAROOTDIR/info]
+ --localedir=DIR locale-dependent data [DATAROOTDIR/locale]

+ --disable-fpu Disable floating-point
+ --disable-64bit Disable 64-bit mode
+ --enable-rvc Enable instruction compression
+ --disable-vec Disable vector processor
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if

+ CXX C++ compiler command
+ CXXFLAGS C++ compiler flags
+ STOW_ROOT Root for non-native stow-based installs
+ STOW_PREFIX Prefix for stow-based installs
+ CPP C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+# This script will create a version string by querying a version control
+# system. The string is appropriate for use in installations and
+# distributions. Currently this script assumes we are using git as our
+# version control system but it would be possible to check and see if we
+# are using an alternative version control system and create a version
+# string appropriately.
+#
+# The script uses git describe plus a few other git commands to create a
+# version strings in the following format:
+#
+# X.Y[-Z-gN][-dirty]
+#
+# where X is the major release, Y is the minor release, Z is the number
+# of commits since the X.Y release, N is an eight digit abbreviated SHA
+# hash of the most recent commit and the dirty suffix is appended when
+# the working directory used to create the installation or distribution
+# is not a pristine checkout. Here are some example version strings:
+#
+# 0.0 : initial import
+# 0.0-3-g99ef6933 : 3rd commit since initial import (N=99ef6933)
+# 1.0 : release 1.0
+# 1.1-12-g3487ab12 : 12th commit since release 1.1 (N=3487ab12)
+# 1.1-12-g3487ab12-dirty : 12th commit since release 1.1 (N=3487ab12)
+#
+# The last example is from a dirty working directory. To find the last
+# release, the script looks for the last tag (does not need to be an
+# annotated tag, but probably should be) which matches the format rel-*.
+# If there is no such tag in the history, then the script uses 0.0 as
+# the release number and counts the total number of commits since the
+# original import for the commit count.
+#
+# If the current directory is not within the working directory, then the
+# path to the source directory should be supplied on the command line.

+This C source fragment is part of the SoftFloat IEC/IEEE Floating-point\r
+Arithmetic Package, Release 2b.\r
+\r
+Written by John R. Hauser. This work was made possible in part by the\r
+International Computer Science Institute, located at Suite 600, 1947 Center\r
+Street, Berkeley, California 94704. Funding was partially provided by the\r
+National Science Foundation under grant MIP-9311980. The original version\r
+of this code was written as part of a project to build a fixed-point vector\r
+processor in collaboration with the University of California at Berkeley,\r
+overseen by Profs. Nelson Morgan and John Wawrzynek. More information\r
+is available through the Web page `http://www.cs.berkeley.edu/~jhauser/\r
