Phoronix: LLVM Introducing JIT Support For OpenMP Offloading

LLVM's GPU/device offloading support continues to advance and this open-source compiler stack has now added basic JIT (Just In Time) compilation support to its OpenMP offloading capabilities...

Is there anything in place that would allow in the future intel arc support as well, or openmp llvm support is completely missing in case of intel?

Distros like Ubuntu have compile support for its packages FOR SOME RECENT architecture and it may happen that 64bit CPUs from 2010 era(although not so much obsolete) its support could be taken down in Ubuntu... I think that Ubuntu should take their advantage from compiler advancement and make possible some environment flags which enable some speedup or something for programs on recent CPUs... If program or snap take some more space(or distilled on snapcraft.io when fetched)...

Some people may think that distros like Gentoo(which support even i586 now, or some SSE,AVX things...???) was research for, but on Gentoo is special one thing: when speculating with its flags like O3 and so on, it became very unstable or compile don't happen... Now we have Github and although in Linux world there is currently only ELF runtime, Google showed that Linux ecosystem is a lot of milestones behind what should be done... And Intel knows this...
