[llvm-dev] Linker error while building a new back end in the latest LLVM from GitHub

Hello.
     I am trying to build against the latest LLVM source from GitHub (from Jan
23 2021) my
Connex processor back end, which is mostly inspired from the BPF and Mips back
end.
     I did my best to correct all the errors that appeared, but I now get a
rather strange
linker error that I don't know exactly how to solve (maybe somebody is more
experienced
than me on this). Maybe I have an error in lib/Target/Connex/CMakeLists.txt.

    The error I get while building LLVM is:

[llvm-dev] Linker error while building a new back end in the latest LLVM from GitHub

Hello.
     I would like to come back to this message.
     It seems the reason of these linker errors are some changes performed in
LLVM itself
in the last 2 years, since I am able to run my back end in an older LLVM build
downloaded
from the source repository in Mar 2019. I apologize for being a bit in the haze
- I didn't
follow closely the changes performed to LLVM lately.

     If interested please find my main CMakeLists.txt for my Connex LLVM back
end:
