Some of the code is inspired from my x86 dynamic translator present in QEMU, but there are important differences because here it is an interpreter. The CPU is close to a 486 compatible x86 without FPU. The lack of FPU is not a problem when running Linux as Operating System because it contains a FPU emulator. In order to be able to run Linux, a complete MMU is implemented. The exact restrictions of the emulated CPU are:

No FPU/MMX/SSE

I compiled a 2.6.20 Linux kernel (I guess any other version would work provided there is still an FPU emulator). The Linux kernel configuration, patch and the source code of the Linux starter (kind of BIOS) are available: linuxstart-20110820.tar.gz.
|
||||
The disk image is just a ram disk image loaded at boot time. It contains a filesystem generated with Buildroot containing BusyBox. I added my toy C compiler TinyCC and my unfinished but usable emacs clone QEmacs. There is also a small MS-DOS .COM launcher I use to test the 16 bit emulation with a tiny .COM program to compute pi and a small self-assembling assembler for MS-DOS.

De-obfuscated JSLinux
|
||||
=========================================================
|
||||
|
||||
I wanted to understand how the amazing [JsLinux][1] worked. However, Mr Bellard seems to have applied a decidedly french proclivity towards obfuscatory algorithmic prose, replete with two-letter variable names and the like...
|
||||
|
||||
So in order to better understand the code, I started transforming all the symbols, which isn't all that hard a thing to do given that it's been built to imitate a very well-specified piece of hardware.
|
||||
|
||||
### Stats
|
||||
|
||||
It's still absolutely ungainly, but not nearly so ungainly as the original. About a third to a half of the variables/function names have been redescribed.
|
||||
|
||||
I highly recommend, by the way, the excellent [JSShaper][2] library for transforming large javascript code bases.
|
||||
|
||||
### Caveat Coder
|
||||
|
||||
This is an artistic reinterpretation of Fabrice Bellard's original code. There's no alteration in the acutal algorithmic content. I do make sure that it still runs. I can't guarantee anything else.
