Kaj de Vos Posted July 11, 2021 Share Posted July 11, 2021 Previous program here My new programming language now has an extra backend that generates 6502 machine code directly, without generating C and going through CC65. One of the benefits is that I have been able to implement the special, relocatable program format of SpartaDOS X. Here is the Rainbow demo that I posted earlier, now compiled for SDX: https://language.meta.frl/examples/platforms/Atari/8-bit/SpartaDOS-X/RAINBOW.COM The program file is only 29 bytes. SpartaDOS X loads it wherever MEMLO happens to be and runs it from there. The program code is here: The new backend produces simple listings of the generated code, which are mostly its internal data structures: https://language.meta.frl/examples/platforms/Atari/8-bit/SpartaDOS-X/rainbow.list The backend doesn't support as much of the language yet as the CC65 backend. This is a lot of work and will happen over time. I believe this is the first compiled programming language that supports SpartaDOS X, beyond assembler and the interpreted SDX batch language. I am very happy how it is turning out. It's the fulfilment of everything I wanted to do three decades ago. ? 2 2 Quote Link to comment Share on other sites More sharing options...
