[cfe-dev] How to deal with new build failures due to new warning? Was: Re: buildbot failure in LLVM on clang-with-lto-ubuntu

[Roman Lebedev via cfe-dev]

Hi everyone.

In D33102, -Wcast-qual was implemented for C++,
so naturally it now produces warnings for clang codebase.

That specific warning
(cast from 'a' to 'b' must have all intermediate pointers const
qualified to be safe)
is clang-specific, i'm pretty sure gcc does not produce it.

To be perfectly honest, i did not thought about trying
to build llvm/clang with the clang with that warning beforehand.

So here is the question: how to proceed?
Revert? Disable that diagnostic? Etc?

Roman.
