==============  RELEASE 0.3.6  ==============

20051008	The bug was not because of faulty ARM documentation after all,
		but it was related to those parts of the code.
		Fixing the RTC (dev_mc146818) to work with CATS.
20051009	Rewriting the R() function; now there are 8192 automatically
		generated smaller functions doing the same thing, but hopefully
		faster. This also fixes some bugs which were triggered when
		trying to compile GXemul inside itself. :-)
		Adding a dummy dev_lpt.
20051010	Small hack to not update virtual translation tables if memory
		accesses are done with the NO_EXCEPTION flag; a time reduction
		of almost a factor 2 for a full NetBSD/cats install. :-)
20051011	Passing -A as the default boot arg for CATS (works fine with
		OpenBSD/cats).

==============  RELEASE 0.3.6.1  ==============

32     # This is a minimal configure script, hardcoded for GXemul. This script
33     # figures out which compiler flags will work, and creates Makefiles in
34     # sub-directories. A config.h file is also created.
35     #
36     #
37     # ---> FOR NORMAL USE, JUST RUN ./configure WITHOUT OPTIONS!
38     #
39     #
40     # To compile the emulator with profiling (during development), use
41     # CFLAGS="-pg", run the emulator, and then run 'gprof gxemul' and study
42     # the results.
43     #
44     #
45     # The main things that are detected by this script:
46     #
47     # o) special hacks for some OSes
48     # o) which compiler to use (overridden by setting CC)
49     # o) which compiler flags to use (overridden by setting CFLAGS)
50     # o) X11 flags and libraries (TODO: should be possible to override)
51     # o) binary translation (on supported platforms)
52     # o) prefetch capability (TODO: this is assumed on Alpha, but not all
53     # Alphas have it...)
54     #
55 dpavlin 10 # TODO:
56     # o) do not enable prefetch on Alpha ev4 or ev5, only on pca56 and newer
57     # o) X11 libs and includes via command line options?
