Hi,

Yeah one would assume something like that exists, I mean there's llvm-mos so why not llvm-dos?

I think I have mentioned this project before:
https://github.com/jayschwa/dos.zig

It's not much, but it's something. It generates a COFF image which can then be run in DOS with some help from CWSDPMI.
(Yes I've tried the demo, seems to work fine in DOSBox).
Zig is/was originally based on llvm and it can compile C/C++ code, to the extent that it can be used as a make replacement.

There's also another option: If you can generate a win9x binary, some of those can be run in DOS via HX.
This is somewhat limited too, so it really depends on what it is you want to achieve.

Hey, thanks for the link.

Basically I was hoping to find a clang/llvm replacement for Watcom. As much as I love Watcom, it’s missing a lot of modern comforts (auto, constexpr, lambdas, stuff like that).

I’m actually a little bit surprised that there isn’t a fork out there that adds DOS 32bit support to clang/llvm. 😀

You already considered and eliminated DJGPP?

Prebuilt djgpp toolchains for Linux, Windows and Mac:

It's up to GCC 12.2 at the moment, so pretty recent. Not sure what more features clang/llvm will give you than that for Dos?

I haven’t and didn’t, that’s a very good point!
