Full circle, there's also djgpp and openwatcom for semi-modern retro development. https://www.delorie.com/djgpp https://openwatcom.org I collect retro compilers, programming books, software, and hardware. - Source: Hacker News / about 1 year ago
  • I want to start learning how to program DOS games
    I recommend using Open Watcom, particularly the Open Watcom V2 fork, to target 32-bit protected mode DOS, rather than 16-bit real mode. Source: almost 2 years ago

    'Computer Architeture: A Quantitative Apporach" and/or more specific design types (mips, arm, etc) can be found under the Morgan Kaufmann Series in Computer Architeture and Design.

  • Programming from Top to Bottom - Parsing
    You can never mistake type_declaration with an identifier, otherwise the program will not work. Aside from that constraint, you are free to name them whatever you like, there is no one standard, and each parser has it own naming conventions, unless you are planning to use something like LLVM. If you are interested, you can see examples of naming in different language parsers in the AST Explorer. - Source: dev.to / 3 months ago

    C++ compiler which compiles the Rust as if it were C++ (LLVM). Source: 5 months ago
  • Bring garbage collected programming languages efficiently to WebAssembly
    LLVM isn't a virtual machine, but WASM is. That's obviously a common misconception given the name -- LLVM was meant to be a VM early in its life, but never was, and isn't now. It's clarified in the first sentence of a home page - https://llvm.org/ It's basically a bunch of C++ libraries that implements an IR that changes over time, which help you write compilers. Curiously, I think a decade or more ago there was... - Source: Hacker News / 6 months ago
  • I'm wanting to write my first compiler, but getting a little bit mixed up in general.
    This will be much easier using tools like LLVM, but this is the basic outline of creating a compiler. Source: 11 months ago
