I wanted to test something 64bit on my new Qemu build, and for the heck of it wen to check out AROS.
And much to my amazement, there is a working x86_64 in the nightly build, 20131104!
x86_64 Aros
To me it’s very cool to see a 64bit AROS… It’s the kind of thing we’d only dream about back in 1993.
They blew the 11/11/11 launch date. Â I guess Oracle really just doesn’t care about magical numbers or whatever.
I guess for the two or three people who even run this stuff (no doubt to run Oralce and it’s draconian licensing) you can find out all about it here.
It appears they still keep the Fortran stuff around for it… Â Oh and this release is x86_64 only. Â Sorry 32bit users.
Installing gcc (and I imagine everything else) revolves around the pkg command… In this case ‘pkg install gcc-3’ will download and install gcc 3. Â While ‘pkg install gcc-45’ will install GCC 4!. Â Don’t forget to install system/header or you won’t have things like stdio.h!!
Another GCC tidbit, is that you can build 64bit binaries with GCC 4.5 by supplying the -m64 flag!
While Solaris 11 installs somewhat quickly in VirtualBox (but wow does it take forever to boot), it is bare minimum…
Also for those who want it, here is lynx & ircII for Solaris Oh and a Quake World Server. Â At least wget is in the base, but I don’t see why lynx isn’t.
it doesn’t do much, but it does work!.. I saw it mentioned here, and the source archive can be downloaded here.
So I went through the steps of  building a 64bit cross tool to build it.. Although Qemu won’t boot the kernel directly, and it uses GRUB which isn’t so bad but I haven’t made a transparent boot system for it just yet…  Maybe I can use a CD-ROM ISO image…

The ‘warnings’ are all my fault… As I wanted a string not the 1,2,3,4…
Grub boot flags
And here we are in 64bit long mode!
So for the two or three people who care, my archive is here… I may move crap around, but at the same time building a 64bit cross compiler was a real chore.. More so because that x86_64-elf bare targets didn’t exist until some time around 4.3.2 which… is involved to build.
It’s been a while since I’ve tried to run some 64bit versions of windows so I downloaded some from MSDN, and tried to run some under the latest 0.14.0 build…
First up is Windows XP x64 sp2 (en_win_xp_pro_x64_with_sp2_vl_x13-41611.iso)
I launched it like this:
qemu-system-x86_64.exe -m 1024 -hda six64.disk -L pc-bios -cdrom en_win_xp_pro_x64_with_sp2_vl_x13-41611.iso
And the bootloader loads up, but it hangs transitioning to the kernel. Nothing is logged to the serial port.
Next up is Windows 2003 server, with no service pack.
I’m loading up Qemu like this:
qemu-system-x86_64.exe -m 1024 -hda six64.disk -L pc-bios -cdrom \install\en_ws_2003_std_x64_vl.iso
And again being met with a hung state booting the kernel.
I guess this isn’t surprising as booth 2003 & XP x86_64 both use the same kernel.
Next up, I thought I’d try a longhorn beta…
qemu-system-x86_64.exe -m 1024 -hda six64.disk -L pc-bios -cdrom longhorn-some-random-beta-x86_64.iso
And I get a nice black screen, again transitioning to the kernel…
So let’s try Windows 2008r2 (It’s the same thing as Windows 7).
So this is different, so googling around for the Stop: 0x0000005D (0x0000000078BFBF9,0x0000000000000000,0x0000000000000000,0x0000000000000000 code, led me to some config file for the x86_64 for additional CPU types. It appears that in the arch_init.c file I modified the following line:
const char arch_config_name[] = CONFIG_QEMU_CONFDIR “/target-” TARGET_ARCH “.conf”;
Into:
const char arch_config_name[] = “./target-” TARGET_ARCH “.conf”;
So that way I could pick up the ” -cpu Nehalem ” flag. Sadly it produced…
Bummer.
Meanwhile, much like Novell Netware, it really only works on Qemu 0.9.0
But not so hot for Windows 2008 r2 (AKA Windows 7).
Because then I see something like this come my way as a query from google:
“is there a version of colossal cave adventure that runs on 64 bit systems”
Well I certainly can’t let that one go unanswered.
So whomever you are stranger, here it is. Well for Win64 x86_64 machines.
This is built using f2c on MinGW64. I’ll spare you the details, but it compiled, and fired up and I got lost in the woods… So I assume it is working…..
For those of you not in the know, colossal cave adventure, or sometimes known simply as ‘adventure’ is the grand daddy of all text adventure games.
As mentioned in this timeline of adventure versions, adventure was written by Willie Crowther and expanded by Don Woods. This version, the Kenneth Plotkin version was derived from Kevin Black’s DOS version and Bob Supnik’s Decus versions.
With that said, there is a tonne of INT2 and INT4 casting, which I’ve just removed as I’m passing it through f2c. I suppose I could have seen about fixing the variables, but I just fixed the ones f2c and gcc really complained about. Included in the download is the modified source, and the original source, so anyone can take a look at it.
Naturally Wikipedia has a most excellent article on the history of adventure, check it out.
Colossal Cave in 64bits!
Enjoy!
Well after yesterdays x86_64 excitement, I figured I’d take a look in the windows area to see about the 32bit vs 64bit performance on Windows…
I know this isn’t the ‘best’ test as I’m using VMWare Fusion on OS X and running Windows XP x64 sp2 (the 2007 edition, not the 2003 one).
If anyone wants to know how to get a 64bit gcc on windows, this is the best formula I’ve come up with so far.
First download a build of mingw-w64-bin_x86_64 from sourceforge… Right now I’m using a ‘Personal Build’ from sezero_20101003, because… it’s recent, and I would imagine a personal build has some hope of actually working.
I downloaded that, and extracted to the root of the C drive. Then I renamed the mingw64 to mingw.
Next up, I downloaded and installed MSYS 1.0.11, and installed that. I selected the default options, and of course specified my mingw is installed in
C:/mingw
After that, I install the MSYS DTK 1.0, again with default options.
The final part is some kind of editor, I like VIM but it’s… involved to download as the default package ‘vim-7.2-1-msys-1.0.11-bin.tar.lzma’ is in a 7zip compatible archive that needs a bit of tweaking to get a tar file out of. I can provide it here in gzip format, that you can simply extract within the msys command prompt in the /usr directory.
Now with all that done, you should be in business!
$ gcc -v
Using built-in specs.
Target: x86_64-w64-mingw32

try
Thread model: win32
gcc version 4.4.5 20101001 (release) [svn/rev.164871 – mingw-w64/oz] (GCC)
But will it run Dungeon?
What is also cool, is that this build of mingw includes gfortran, which is a Fortran 95 compiler with various 2003 & 2008 enhancements. So for the heck of it, I’ve rebuilt the makefile from dungeon-2.5.6 and tweaked the machdep.f to at least call the ITIME function to get the current time. The resulting archive runs pretty well!
Yes, it runs! And without a *32 meaning this is a 64bit binary!
Onward with SIMH
So going back to SIMH as my benchmark, here is the vax780 with -O0/-O0
Dhrystone(1.1) time for 500000 passes = 18
This machine benchmarks at 27777 dhrystones/second
Dhrystone(1.1) time for 500000 passes = 20
This machine benchmarks at 25000 dhrystones/second
Dhrystone(1.1) time for 500000 passes = 19
This machine benchmarks at 26315 dhrystones/second
Which comparing it to the native x86_64 build is pretty good considering I’m running this in a VM (VMware Fusion!). Now the same test with -O1/-O1
Dhrystone(1.1) time for 500000 passes = 12
This machine benchmarks at 41666 dhrystones/second
Dhrystone(1.1) time for 500000 passes = 12
This machine benchmarks at 41666 dhrystones/second
Dhrystone(1.1) time for 500000 passes = 12
This machine benchmarks at 41666 dhrystones/second
Which is pretty good! Now for the finally with -O2/-O1
Dhrystone(1.1) time for 500000 passes = 12
This machine benchmarks at 41666 dhrystones/second
Dhrystone(1.1) time for 500000 passes = 12
This machine benchmarks at 41666 dhrystones/second
Dhrystone(1.1) time for 500000 passes = 12
This machine benchmarks at 41666 dhrystones/second
Which is interesting in that there is no appreciable difference in the -O2/-O1 vs the -O1/-O1 build. Although I kind of expect different results on a native machine. If anyone else cares to test, I’m going to make available the whole project here. This includes the source and the pre-built binaries.
Unzip it on a win64/win32 machine and it should be somewhat straightforward to build / run. You can alter the makefile and change the primary CC flags from O0 to O1 or O2 if you so wish… just run make and it’ll generate a vax780.exe . Then in the test directory you can bench your exe like this:

The d0,d1,d2 are the dhyrstone benchmark compiled with -O0, -O1, and -O2 respectively. This gives you a chance to observe various optimizations in the GCC 2.7.2.2 for the VAX.
more etc…
Some of the stuff is getting ironed out, it plays better for sure.
I had to start separating things out to make some older C compilers happy…
I still do not understand how ‘float’ types keep changing sizes between 16bit/32bit compilers…. Was there ever ANY consistent floating point types in C between 16/32bit? It really sucks to have binary data and find out you cannot ‘read’ it…..
Did people just force people to dump their data into ASCII, and reload it into 32bit formats, and tell everyone to ONLY use 32bit?
I know I’m like 15 years late to this party, as everyone is going through the win32 to win64 thing… Although I’m surprised Tradewars C’s win64 version runs happily with a win32 generated data file…….
Oh and ports in this version:
MS-DOS (realmode)
Win16 (QuickC for Windows’s QuickWin)
Win32 (Visual C++ 1.0’s CLI libc.lib exe… )
Win64 (Visual Studio 2008 cli)
Linux (x86 built with debian -static…..)
OS/2 (16 bit built with Microsoft C 6)
Although it supports multiple users, it’s still a single player game… I suppose it shouldn’t be too hard to constantly check the user record & sector record of where they are with stuff changing…..?
Anyways my work is here: https://sourceforge.net/projects/tradewarsc/
Well I screwed up the Proxmox VE thing and I needed to test some x64 stuff… Sadly the VM I used to build the x64 stuff was the proxmox… And I need it now!
So I found this site, which has the new qemu stuff built!
Just unzip it with 7zip.
And you should be good to go..
However for Windows 2003 x64 R2 it seems that those binaries crash on ‘starting windows’, apparently they were compiled with GCC 4 while the ancient qemu 0.90 built with GCC 3 works…
I’ve also found a source ‘fix’ for why 0.91 crashes on vista…:
patch hw/ide.c:
just replace all ‘free(buf)’ in guess_disk_lchs function to ‘qemu_free(buf)’.
Sounds easy enough. I’ll have to get a working toolchian.
