Subject: Building RTEMS with LLVM toolchains,

Good evening,

I'm writing to this list to let you know that there is currently project underway (LLVM for space Applications)
done between Frontgrade Gaisler, N7Space and Spacebel under ESA that aims to improve LEON5 and NOEL-V software support. One of the activities currently done by Gaisler is adding support for those CPUs to LLVM project, in parallel
N7Space is adapting RTEMS and RSB for building LLVM based toolchains for RTEMS and adapting RTEMS to compile
with those. 

Some of the work will be published shortly, as of now we adapted RSB to build LLVM-based toolchains for sparc and riscv architectures and RTEMS itself can be compiled with those. 

What is the acceptable format of the contributions to RTEMS project? Sending patches for RSB and RTEMS to this list, or is it managed in some other way?   

?Best regards/Pozdrawiam

Hi Daniel,

This sounds great. We prefer contributions through our GitLab:
https://gitlab.rtems.org/

We have some documentation about that in a few places:
* https://docs.rtems.org/docs/main/user/support/contrib.html
* https://docs.rtems.org/docs/main/eng/vc-users.html

This email list is probably not well monitored these days. You may get
better responsiveness on our discord ( https://www.rtems.org/discord )
or in our User's Forum discourse ( https://users.rtems.org/ ).
