In particular, we require VS 2015 or above, which doesn't support anything older than Server 2008 anyway (including Vista and XP), and I doubt we'd have anyone using Server 2008.
For llvm itself, yes, but this is for the runtimes. Or does the policy cover that as well?

Mingw upstream still(!) default to supporting xp onwards, while I'm configuring my own setups to default to vista. I guess making that 7 wouldn't be too much of an issue though.

FWIW, I included a corresponding change for ASAN here: https://reviews.llvm.org/rCRT343074, in adding a `append_list_if(MINGW psapi ASAN_DYNAMIC_LIBS)` in compiler-rt/trunk/lib/asan/CMakeLists.txt.
