[cfe-dev] VS2017: LLVM Compiler Toolchain Plugin

[Zachary Turner via cfe-dev]

I hadn’t seen that blog post, thanks!

I don’t have a particularly strong opinion on the stdout option, but
several other project members do. Can you elaborate on why you think it
should be on by default (and separately, why it should not be possible to
disable)? The thinking on our side is that this is a task better handled by
the build system, and presently most build systems today just end up
filtering this out anyway.

My current idea for how to implement this is to have clang detect the
presence of a magical undocumented environment variable, and have the
MSBuild integration just set this variable.
