[Pkg-julia-devel] Bug#919593: julia: Please use LLVM 6.0 packages

[M. Zhou]

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.

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

Recently in discussions with ginggs we reached an agreement to ignore
the NEON code problem on armhf ... and I've found no solution for it.
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.
