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 alpha, arm, arm_thumb, avr32, ia64, m68k, mips, parisc, ppc, s390, sh3, sparc, vax, x86 and x86_64 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.

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.
• 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:

• 6502: (Screenshot of results) I have a few Apple II machines, but most development was done on the yae emulator.

Yet to come:

• pdp-11: ???
• All other known Linux architectures: thumb2, sh4, blackfin, cris, frv, h8300, i960, m32r, v850, xtensa
