[Pkg-julia-devel] julia and llvm11

[Norbert Preining]

Hi all,

it seems that we have at least managed to build armhf now, good to hear.

You might have seen the bug report that just came in asking for
switching to llvm11. I thought I try it out, but the build failed - not
completely unsurprisingly.

I searched a bit in the julia git/github, and it *should* work

[LLVM] upgrade to LLVM 11
https://github.com/JuliaLang/julia/pull/37842

LLVM11 Compatibility
https://github.com/JuliaLang/julia/pull/35112

but still, the build fails for me. First there are a lot of deprecation
warnings concerning llvm::VectorType*, and then there is an error in
codegen:

Any ideas or insights?
