MinGW-w64

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
Configured with: ../gcc44-svn/configure –host=x86_64-w64-mingw32 –target=x86_6
4-w64-mingw32 –disable-multilib –enable-checking=release –prefix=/mingw64 –w
ith-sysroot=/mingw64 –enable-languages=c,c++,fortran,objc,obj-c++ –enable-libg
omp –with-gmp=/mingw64 –with-mpfr=/mingw64 –disable-nls –disable-win32-regis
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!

Windows XP x64 - dungeon

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 updates on the 4.2BSD project thing

I updated the website after 2+ years of stagnation… lol

http://bsd42.sourceforge.net/

I know its sad, and mostly all licensing… Anyways I’m in the process of moving so no major updates in the next week to two… But once I’m settled up in New York, I’ll crank out another set of releases to include working cursor control for games, and a loaded version of Uwisc BSD with all the fun stuff ready to roll… I’m also going to do a “HP” install of Reno so it won’t be an 80Mb download anymore… I figure if people are actually using them, they can modify the configs, add more disks etc etc….

Which reminds me if there is a online 1st edition copy of the “Unix System Administration Handbook”.. That’d be cool, but otherwise, I’d recommend people to get a copy of the 1st edition as it covers the tail end of the VAX era BSD’s.

Update for HACK

I just found out that hack will run properly if it’s built with the default compiler PCC (cc). However there is a single file that will not build, but gcc can be used to build the single file, and the build process can continue as normal.

Here is a quick log:

myname# make
cc -g -c hack.Decl.c
cc -g -c hack.apply.c
cc -g -c hack.bones.c
cc -g -c hack.c
hack.c: 799: missing endif
*** Error code 1

Stop.
myname# gcc -g -c hack.c
myname# make
cc -g -c hack.cmd.c

cc -g -c rnd.c
cc -g -c alloc.c
Loading …
myname# size hack

myname# strip hack
myname# ls -l hack
-rwxrwxr-x 1 root 206848 May 10 10:23 hack

And with that being said, it seems just about any version of GCC will do… from 1.27 to 2.45. I’ve test played it, and you get the tombstone when you die, not a core dump. This applies to 4.2 BSD and all the 4.3 BSD’s. I’ve updated the sourceforge binary packages that I have made for Hack to include this hybrid exe that seems to work just fine.

Happy hacking!

Hack

 

Hack is the precursor to NetHack, and the follower of rogue. It’s a fun game, however I thought it would be a great addition to my 4.2 BSD project stuff. Thanks to the awesome site NetHackWiki I was able to quickly find Hack 1.0.3, download it, convert it into a tape for SIMH, and get it compiled. In it’s present state it does core dump when exiting, I’m not all that sure as to why, and to be honest I’m not all that good with adb. Perhaps a project for another time.

At any rate, the game is somewhat playable.

GCC is required to compile the source, pcc chokes when trying to build. I have made minor modifications to the source with regards to some variables, and renaming variables called ‘inline’..

If the COMPAT_42 is built with any later BSD it should run the binary otherwise producing your own ought to be trivial.

The binary is located here.

The modified source is here.

I’m sure there are all kinds of mods like PC hack to run it under DOSBOX or some kind of Windows thing, but it’s more fun running it under a VAX 11/780 emulator…

Pointless update of the day (iPhone fun!)

I got a used iPhone while on vacation, and I managed to jailbreak it, and load up the CLI tools, including gcc onto it… It feels VERY unixy now with the 2.0 os, all the good stuff like screen, lynx, vi .. So I decided to build SIMH on it. It takes FOREVER to build anything… But then I don’t think the iPhone was built to compile.. -O2 seems to break so sadly it’s without optimizations but it runs!

For the heck of it, I copied in my 4.2 BSD disk image, and rebuilt SIMH with SLiRP support, and now I have a hand held VAX!

It’s cool, and pointless at the same time… I’ll probably make some binaries available on sourceforge later.. I guess as iPhones eventually get phased out (1st gen ones for sure) it’d be cool to let them become servers or something useful along those lines…

Here is a screen shot for the curious…

And yes, you can telnet into it, via the magic of SLiRP… I’ve tried building some irc clients, really old stuff does build and “work” but I think the server protocol has drifted as it cannot join any rooms…. So close & yet so far away.. I’ll probably have to move to 4.3 BSD..

I also should add that the iPhone VAX feels like an 11/780.. In that it takes several minutes to boot… Don’t expect a FAST machine…!

Yet another update! networking for 4.2 BSD

4.2BSD telnetI have released yet another interim update to my VAX BSD on Windows installer package.

I redid the 4.2BSD package, so anyone that has downloaded, will want to download again (there were 2 downloads… )

Anyways I found a source tree of 4.2 BSD with the if_de.c and the same fix for the 4.3 BSD’s worked fine for this one as well. Now you can telnet into 4.2 BSD!

You can download it from here:

https://sourceforge.net/project/showfiles.php?group_id=204974&package_id=245145

It is worth noting that I didn’t even look at the TCP/IP stack so it’s possible that you could be hit with issues with negative numbers in the TCP sequencing, and other weird 4.2 to 4.3 bugs.

Also attempting to fix locore.s to allow more then 8mb of ram seems to have a kernel that hangs right after mounting the root partition.. If anyone remembers what to do to fix it, I’d appreciate it. I see in google’s usenet cache, they had the same issue at Nova University, but I didn’t see any follow up for a fix.

This update now brings all of the 4BSD packages on Windows up to a network operational level. Also please note that they all use the same user mode mapping ports (ie 42323 to 23 into the VM) so you currently cannot operate all of them at the same time. If that is an issue for anyone you can regen the exe’s from the SIMH project page:

https://sourceforge.net/project/showfiles.php?group_id=154308&package_id=244757

Otherwise you can just contact me.

 

Updates on my sourceforge BSD/SIMH packages

On my project page I have made some new packages for 4.3BSD & 4.2BSD. Both of which can be downloaded here.

The updates include:
-moving to 3.8-1 of SIMH
-turning off unnecessary services in BSD
-moving from putty to Tera Term
-fixing PDF documentation links..

While not a major update, I figure since people are still downloading the 4.3 BSD RENO version as of TODAY I figure an update for these people wouldn’t be such a bad thing…

As before they are windows install packages, although I guess if you were so motivated you could extract them on some kind of *nix box..
