  Compiler for the stack-based Whitespace language with LLVM back end. (by thaliaarchi)

I built an AOT compiler for Whitespace with its own SSA-form intermediate representation that lowers to LLVM IR. Whitespace is very similar to a minimal Forth, except, well, syntax. Since StoneKnifeForth has no filesystem access, only stdin and stdout, the principles could be easily adapted for Whitespace.

• PropForth5.5

  PropForthV5.5 is Forth progamming environment for Parallax Propeller P8X32A microcontroller created by Sal Sanci

>If you want to counter Ken Thompson’s “Trusting Trust” attack, you would want to start with a minimal compiler on a minimal chip; StoneKnifeForth might be a good approach.

Some people have been working on fairly good Forths for different, minimal hardware including the Parallax boards.

There's also Chuck Moore's GreenArrays GA144 if you want a high performance Forth machine which includes a proto area on the board.

• tokthr

  2 35 0.0

  tiny token-threaded bytecode interpreter in x86 assembly

SKF's predecessor tokthr was derived from Jonesforth: https://github.com/kragen/tokthr/blob/master/tokthr.S

IIRC the reason I only allowed single-byte identifiers was to simplify the symbol table, which is implemented by these four lines of code:

    : Type Four* header 6144 + + ; ( Table of definition Types: 1=code, 2=data )

Thanks, SOD32 looks interesting. It also led me to find this: https://github.com/kt97679/relf
