ll: Linux_Logo in assembly language

latest version is 0.36

20 Architectures, Smallest Linux executable is 905 bytes! (on crisv32)

NEWS:

I released version 0.36 on 3 March 2009. It removed some extraneous unneeded files from the distribution.
I released version 0.35 on 13 February 2009. Added z80 support.
I released version 0.34 on 28 January 2009. Added pdp-11 support.
I released version 0.33 on 21 January 2009. Added m88k support.
I released version 0.32 on 7 January 2009. Added crisv32 support.
I released version 0.31 on 9 September 2007. Added 6502 support.

BACKGROUND:

This is a port of my linux_logo program to use raw assembly language. By using assembly and syscalls, you can have extremely fast and small binaries that don't use libc at all!

So far I have 6502, alpha, arm, arm_thumb, avr32, crisv32, ia64, m68k, m88k, mips, parisc, pdp-11, ppc, s390, sh3, sparc, vax, x86, x86_64, and z80 versions.

If you have an unsupported architecture and will be willing to give me a shell account on your machine, let me know. It would be great if every Linux-supported architecture had its own assembly version of linux_logo.

Linux assembly source files for your viewing pleasure:

Non-linux versions:

Read the m88k OpenBSD assembly source.

8 and 16-bit versions:

Read the 6502 source for the Apple ][
Read the PDP-11 source for a PDP-11 running UNIX v7.
Read the z80 source for CP/M
Read the RiSC source for the research-only 16-bit RiSC archirecture

Here is a comparison of the size of the binaries after having sstrip run on them:

Architecture	Size
pdp-11	890 bytes
crisv32	905 bytes
avr32	914 bytes
z80	920 bytes
x86	976 bytes
arm_thumb	989 bytes
sh3	994 bytes
vax	1010 bytes
m68k	1014 bytes
x86_64	1036 bytes
s390	1096 bytes
PowerPC	1206 bytes
arm	1218 bytes
m88k	1240 bytes
MIPS	1292 bytes
6502	1394 bytes
SPARC	1397 bytes
PA-RISC	1400 bytes
alpha	1957 bytes
itanium	2874 bytes

For a bit of commentary on why the sizes end up the way they do, see the README

You might ask if all the above works? Yes. Written and tested on:

alpha: "bmul", our dual 21264. Also original thanks to the (now defunct) Compaq testdrive.
arm: "lindt", my gumstix system.
avr32: I have an Atmel NGW100.
crisv32: I used qemu.
ia64: "itanium", our creatively named ia64 machines. Also, original thanks to the (now defunct) Compaq testdrive.
m68k: the aranym emulator, emulating an Atari running Linux.
mips: "perugina", a debian SGI Indy we have at work.
parisc: "feodora", an HP-PARISC machine we have at work.
ppc: "henparma" my 2001 iBook
s390: the Hercules emulator. Also, originally thanks to IBM zSeries Testdrive
sh3: qemu-sh4, and eventually on a dreamcast
sparc: "valor" a 24 processor niagara server we have at work.
vax: simh simulator
x86: "hal" my aging K6-2+ FIC PA-2007 machine
x86_64: domori cluster at work

Non-Linux versions:

m88k: Used the GXemul simulator
pdp-11: (Screenshot) Used the simh simulator
6502: (Screenshot) I have a few Apple II machines, but most development was done on the yae emulator.
z80: Used the Yaze simulator (Screenshot)

Yet to come:

Non Linux: amd29k, att92k (crisp/hobbit)
All other known Linux architectures: thumb2, sh4, blackfin, frv, h8300, i960, m32r, v850, xtensa, microblaze (in progress), mn10300, s+core, trimedia
