20070616	Implementing the MIPS32/64 revision 2 "ror" instruction.
20070617	Adding a struct for each physpage which keeps track of which
		ranges within that page (base offset, length) that are
		continuously translatable. When running with native code
		generation enabled (-b), a range is added after each read-
		ahead loop.
		Experimenting with using the physical program counter sample
		data (implemented 20070608) together with the "translatable
		range" information, to figure out which physical address ranges
		would be worth translating to native code (if the number of
		samples falling within a range is above a certain threshold).
20070618	Adding automagic building of .index comment files for
		src/file/, src/promemul/, src src/useremul/ as well.
		Adding a "has been translated" bit to the ranges, so that only
		not-yet-translated ranges will be sampled.
20070619	Moving src/cpu.c and src/memory_rw.c into src/cpus/,
		src/device.c into src/devices/, and src/machine.c into
		Creating a skeleton cc/ld native backend module; beginning on
		the function which will detect cc command line, etc.
20070620	Continuing on the native code generation infrastructure.
20070621	Moving src/x11.c and src/console.c into a new src/console/
		subdir (for everything that is console or framebuffer related).
		Moving src/symbol*.c into a new src/symbol/, which should
		contain anything that is symbol handling related.
20070624	Making the program counter sampling threshold a "settings
		variable" (sampling_threshold), i.e. it can now be changed
		during runtime.
		Switching the RELEASE notes format from plain text to HTML.
		If the TMPDIR environment variable is set, it is used instead
		of "/tmp" for temporary files.
		Continuing on the cc/ld backend: simple .c code is generated,
		the compiler and linker are called, etc.
		Adding detection of host architecture to the configure script
		(again), and adding icache invalidation support (only
		implemented for Alpha hosts so far).
20070625	Simplifying the program counter sampling mechanism.
20070626	Removing the cc/ld native code generation stuff, program
		counter sampling, etc; it would not have worked well in the
		general case.
20070627	Removing everything related to native code generation.
20070629	Removing the (practically unusable) support for multiple
		emulations. (The single emulation allowed now still supports
		multiple simultaneous machines, as before.)
		Beginning on PCCTWO and M88K interrupts.
20070723	Adding a dummy skeleton for emulation of M32R processors.
20070901	Fixing a warning found by "gcc version 4.3.0 20070817
		(experimental)" on amd64.
20070905	Removing some more traces of the old "multiple emulations"
		Also looking in /usr/local/include and /usr/local/lib for
		X11 libs, when running configure.
20070909	Minor updates to the guest OS install instructions, in
		preparation for the NetBSD 4.0 release.
20070918	More testing of NetBSD 4.0 RC1.

14     <h2>Release notes for GXemul</h2>
16     <p><i>Copyright (C) 2003-2007 Anders Gavare</i>
19     <p><br>GXemul is a framework for full-system computer architecture emulation.
20     Several processor architectures and machine types have been implemented.
21     It is working well enough to allow <a href="doc/guestoses.html">unmodified
22     "guest" operating systems to run inside the emulator</a>,
23     as if they were running on real hardware.
25     <p>The emulator emulates (networks of) real machines. The machines may
26     consist of ARM, MIPS, PowerPC, and SuperH processors, and various
27     surrounding hardware components such as framebuffers, busses, interrupt
28     controllers, ethernet controllers, disk controllers, and serial port
29     controllers.
31     <p>The <a href="doc/index.html">documentation</a> lists the machines and
32     guest operating systems that
33     can be regarded as "working" in GXemul. The best working guest operating
34     systems are <a href="doc/guestoses.html#netbsdpmaxinstall">NetBSD/pmax</a>
35     and <a href="doc/guestoses.html#netbsdcatsinstall">NetBSD/cats</a>.
38     <p><br>The changes between release 0.4.6 and include:
40     <ul>
42     <li>NetBSD 4.0 has been released. The installation instructions
43     in GXemul's documentation have been updated to reflect this.
45     <p><ul>
46     <li>In most cases this simply means that NetBSD 4.0 is now
47     supported instead of NetBSD 3.1.
48     </ul>
50     <p>Some specifics worth mentioning are:
52     <p><ul>
53     <li>For NetBSD/pmax, the change from 3.1 to 4.0 means that
54     X Windows is now working again out-of-the-box. (Simply
55     run <tt>startx</tt> as root to start X.)
56     <li>For NetBSD/arc, the supported version has jumped from
57     1.6.2 to 4.0.
58     <li>NetBSD/prep is unfortunately still at 2.0.
59     </ul>
61     </ul>
63     <p>Please read the <a href="HISTORY">HISTORY</a> file for more details.

80     <p>To build the emulator, run the <tt>configure</tt> script, and then run
81     <tt>make</tt>. This should work on most Unix-like systems, with few or no
82     modifications to the source code.

85     these are written by me, the rest are from other sources (such as NetBSD).
86     The license text says that "All advertising materials mentioning features

88     <i>not</i> feel that I mention features or use of the header files (the
