Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

- LLVM-MOS 6502 Compiler Backend: Having a Blast in the Past
-
I'm sorry honey, it's just not working out. Our relationship worked when we were younger, but we're both older now and we've grown apart. This issue is to fully eliminate LLVM, Clang, and LLD libraries from the Zig project.
Too late: https://github.com/llvm-mos/llvm-mos

Explaining my fast 6502 code generator

How can I compile rust for 16bit x86 (Intel 8086)?
You could look at LLVM-MOS, the port of LLVM to the 6502. It might give you some ideas around the problems to solve https://llvm-mos.org/wiki/Welcome https://github.com/llvm-mos/llvm-mos

The Rise of Rust, the ‘Viral’ Secure Programming Language That’s Taking Over Tech
The MEGA 65 doesn't appear to have shipped yet. The best data I could find is the MEGA 65 is based on a "GS4510". The "GS4510" is compatible with a "4502", which in turn is compatible with the 65CE02. The 65CE02 uses a different manufacturing process but the same ISA as the 6502, which is supported by rust-mos and lvm-mos](https://github.com/llvm-mos/llvm-mos).

A Graphical OS for the Atari 8-bit
It really is a cool project. https://github.com/cc65/cc65
It provides some template configuration files describing different memory layouts. And provides common libraries for input/output.
There's also a LLVM fork for MOS: https://github.com/llvm-mos/llvm-mos
They've got some interesting hacks with ZeroPage memory and register allocation: https://llvm-mos.org/wiki/Code_generation_overview
Interesting if you geek out on that kind of research.

Can you write for the Commodore 64 in Rust? Why yes, yes you can!
Using llvm-mos, rust-mos, a lot of time compiling compilers and support from Mariusz (the rust-mos author), I was finally able to program like it was 1982...

rust gcc backend was officially accepted into the compiler
SNES: 65C816 derivative, may eventually be supported by https://github.com/llvm-mos/llvm-mos

Building GCC 1.27 (first GCC with x86 support) (2019)
Mainstream GCC has never supported 16-bit code on x86, only 32-bit
However, there is (at least one) fork which adds 16-bit code support, see https://github.com/tkchia/gcc-ia16
I don't think the GCC maintainers have ever or will ever want to support 16-bit x86, because it is so limited, and adds a lot of messy corner cases, and nowadays is really only of hobbyist/retrocomputing interest.
Maybe there is some 16-bit x86 embedded system still being maintained–there were military spec versions of the 8086, and possibly some weapons system, aircraft, satellite, etc, still in use contains one. But I doubt they'd have any interest in adopting a 16-bit GCC – they'd already have some proprietary compiler they'd been using for decades, switching now would add a lot of risk, very late in the life of a legacy system, for no tangible benefit

Djgpp
These days there is also a 16-bit GCC port to DOS (https://github.com/tkchia/gcc-ia16). I never encountered one of those back in the day? I think the compiler itself does not run in 16-bit DOS though.
Anyone interested in compiling for DOS (32-bit or 16-bit) should also check out Free Pascal.
-
Rust is Boring
My advice is, when you feel you need that challenge, install DOSBox or DOSBox-X and Open Watcom C/C++, DJGPP, or gcc-ia16 and do some retro-programming. You'll also get the fun of being able to do low-level hardware twiddling and rely on DOS being so simple that it's effectively an RTOS.

Writing FreeDOS Programs in C
Looking at part 1 and some of the videos, it looks like this doesn't actually use OpenWatcom, but i16gcc from the FreeDOS distribution, which looks to be a port of gcc that targets 16-bit x86.

"My Reaction to Dr. Stroustrup’s Recent Memory Safety Comments"
And, if that surprises you, gcc-ia16 is a thing that has come into existence not only over a decade after DJGPP but also after Open Watcom already existed.

How can I compile rust for 16bit x86 (Intel 8086)?
or GCC IA 16 (https://github.com/tkchia/gcc-ia16) gets someday mainlined (also a multi month/years project) and then gccrs can maybe use it as backend
-
Tools and/or tutorials for making a roguelike in DOS?
There is a 16-bit port of GCC these days as well included together with DJGPP if you install FreeDOS, but available separately as well (I think it can cross-compile from other systems like DJGPP can too?) https://github.com/tkchia/gcc-ia16

How FreeDOS Grew Up and Became a Modern DOS
TK Chia and others have been working on adding DOS C/C++ compiler-isms to GCC as well as improving the the codegen to make it more hospitable for DOS apps. So far, the FreeDOS kernel compilable by gcc-ia16.

how to get started programming a game/program for dos?
There is a more recent fork of gcc/DJGPP to make 16-bit DOS applications that I also never tried, but that might be worth using (and I think it is bundled in the latest FreeDOS, so it might be very easy to set up by just installing that in a virtual machine?): https://github.com/tkchia/gcc-ia16
