Hi Sylvestre, F.Y.I.

However it's llvm-7 support is still under development and is not likely to be merged by the stable 1.0.X series. I may have to port some patches from llvm-7 to Debian's llvm-6 for julia 1.0.X, if upstream doesn't release julia 1.1 before Buster release, which would support llvm-7. > * Remove everything but 6 & 7 from the archive to release with only > two llvm versions. (maybe one if we are very lucky? :) IIRC Julia 1.0.X FTBFS with llvm-7. Sorry for the bad news :( If upstream can release 1.1.X before Buster freeze, julia won't block llvm-6 removal.
