Any plans to support 32bit ARM targets

[klvnptr]

Hey. Awesome project. Quick question: Do you have any plans to support 32bit targets? Would be awesome to use bflat with low-cost MCUs. Thanks. Peter

If that's out of reach I wonder if a LLVM target would get you there.

thanks for the feedback @voronoipotato LLVM target would be the best, so ppl could cross-compile to any targets. maybe there is a plan for LLVM IR target ? :)

maybe there's clues in https://github.com/dotnet/runtimelab/tree/feature/NativeAOT-LLVM

ARM32 should be doable, it used to work with NativeAOT but might have bitrotted a bit. dotnet/runtime#69739 (comment) mentions adding this upstream; I don't think there's a dedicated issue.

Once upstream has it, I can pick that up here. Otherwise extending architecture reach beyond what NativeAOT supports is out of scope for bflat. I don't have the kind of time for it (bflat is a side project that I spent ~2 hours a week on for a couple months and I don't plan to increase the commitment beyond that - just keep up with upstream and sometimes add something interesting with a good bang for the buck).

I have ported clrGC to STM32.
It is very difficult to port native aot runtime to STM32.
I implemented “ Try Catch" in bare metal.
