It's good to be coming back to the llvm-dev list... from the time of
LLVM 3.x releases :).
We have added these as Collective Knowledge packages, and tested on
both armv7a (Odroid XU3) and aarch64 (Linaro HiKey960).
You can check them (on Linux, Windows and MacOS; with x86 or arm) as follows:
$ sudo python -m pip install ck
$ ck pull repo:ck-env
$ ck pull repo:ctuning-programs
$ ck install package:compiler-llvm-6.0.1-universal
$ ck install package:compiler-llvm-7.0.0-universal
$ ck virtual env --tags=compiler,llvm
$ ck compile program:cbench-automotive-susan
$ ck run program:cbench-automotive-susan
Cheers,
Anton.
