Do you know if the 6502 LLVM backend has floating point support ? A big problem with CC65 is the lack of floating point support.

EDIT: The answer is no:

What kind of stuff do you want to do on a 6502 that requires emulated floating point support?

It is nice to have, most BASIC versions that run on 6502 micros had floating point support.

The "floating point" support that's in 6502 BASIC ROMs is not real IEEE 754 floating point though, see https://en.wikipedia.org/wiki/Microsoft_Binary_Format So it shouldn't be used to replace that, though of course one can use it for other purposes with some care. (It goes without saying that this is not hardware floating point, so the only potential gain from piggybacking on these ROM routines will be some saving in code size.)

I wouldnt mind generating lookup tables at run time rather than my present system of exporting them via python etc... the algs could be more dynamic!

So maybe someday we could do rust for the c64?

The people old enough to want to program on the c64 are not the same group of younger hipster who want to rustify the world. It would take someone to bridge these groups.

Yup, it's fun to think that the rust_embedded ecosystem could be repurposed with comparable ease to support bare-metal retro programming. Similar to how Rust itself bridges the "low-level C/C++" and "hipster high level language" worlds.

I guess I'm an old hipster that wants to rustify the world? I started on c64 basic as a tiny kid.
