[llvm-dev] Clang 3.9.1 fails to build LLVM 11.0.0

[Issam E. Maghni via llvm-dev]

Hi folks. It’s my first time in this mailing list, and definitely not
the last :)

Recently, I’ve been into bootstrapping compilers. I’ve encountered
several issues, and will start with this one.

The doc claims that Clang >= 3.5 is required to build LLVM 11.0.0 [1].
So I built LLVM+Clang 3.9.1, then tried to build LLVM 11.0.0. Doing so,
I faced this error:
> no matching constructor for initialization of
> 'llvm::ValueEnumerator::MDRange'
(full log here [2])

Don’t worry, I’ve done my job. For a minimal reproducible example, here
[3] is a script that you should execute on a new Debian 10 system, most
likely a VM.

PS: a feedback too about how I report bugs would be awesome!
