Bug#912790: llvmlite: Please switch to llvm-toolchain-7

0.27 uses LLVM 7, although 0.27.0~rc1 doesn't build cleanly yet:

Upstream needs some time to adapt, v0.26.0rc1 (released recently):

"LLVM 7 support was originally slated for this release, but had to be delayed
after some issues arose in testing.  LLVM 6 is still required for llvmlite."

Bug#912790: llvmlite: Please switch to llvm-toolchain-7

[Sylvestre Ledru]

Source: llvmlite
Severity: normal

Hello,

llvm-toolchain-7 is now the default version in Debian.

As part of the effort to keep the number of llvm-toolchain versions under
control, it would be great if you could update to llvm-toolchain-7.

Thanks,
Sylvestre
