Violating architecture baseline is a serious bug, I don't think you get to just ignore it. Please don't ignore the context. That's NOT baseline violation, but just wrong CPU detection by LLVM, and Sylvestre is fixing it. Adrian fixed it already in the vcs I will upload it once I cherry-picked the most important patches Sylvestre

If you have any issue with the current llvm packages, please open bugs and we will adress them. Why are you asking us to use the LLVM 6.0 packages when you are already filing bugs [1][2] against other packages asking them to switch to LLVM 7? Well, if you can use llvm-7, this would be indeed better. The llvm-toolchain-6.0 source package already has a removal bug [3] filed against it! Which doesn't mean it will happen in time for Buster... This is just a meta bug to keep track of the remaining work? Sylvestre

Julia ships embedded LLVM because we want to apply all the upstream patches (although I don't care about the portion of patches for windows). I've filed an bug against LLVM 6 and pointed out the location of upstream patches. Could you share this bug number? Another issue we encountered about LLVM is it's emitting NEON code on armv7, which resulted in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=919183 We can fix this one. S

Hi Sylvestre, Thanks for offering help. Julia ships embedded LLVM because we want to apply all the upstream patches (although I don't care about the portion of patches for windows). I've filed an bug against LLVM 6 and pointed out the location of upstream patches.

Upstream encountered similar problem long time ago[1], but I think we don't have to completely disable NEON now ... since julia compiles multiple code branches.
