Clang/LLVM support for Epiphany?

[ByeByeFlyGuy]

Forgive me if this is a FAQ but searching the forums for LLVM gives nothing but an error. Is there currently support for compiling code to run on the Epiphany processor using Clang/LLVM? If not, is anyone working on this?

The reason I am interested is that the Rust compiler from mozilla (http://www.rust-lang.org/) uses LLVM for its backend code generation, suggesting to me that it might be (relatively) straight forward to allow rust programs to run on the Epiphany processor.

There was some preliminary work a while ago but I think the guy doing the work got busy and didn't have time to continue - viewforum.php?f=24

I too would love LLVM for Epiphany to utilise Python Numba http://numba.pydata.org/ on Parallella but I'm not smart enough to make it work so it's a matter of waiting until someone with skills and interest is able to do something then support them with bug reports/testing when they are ready for it.

Doh - a whole topic hiding below the fold. Thanks for the pointer.

Looks like no-one's touched that for a year or so. One more to add to the list of things to dig into

you can get the latest code (a year old as of now) here: https://github.com/Hoernchen/Epiphany

I think LLVM support will be very interesting, because it'll allow to make use of the very good LLVM API to write epiphany-specific optimization passes. However, I very much doubt that frontends like numba generate code that works very well on the epiphany, since for "normal" super computers size of code and data locality is not as much of an issue.
