Subject: [PATCH] tools build: Fix test-clang.cpp with Clang 8+
Date: Sat, 28 Dec 2019 18:13:13 +0100	[thread overview]
Message-ID: <20191228171314.946469-1-mail@maciej.szmigiero.name> (raw)

LLVM rL344140 (included in Clang 8+) moved VFS from Clang to LLVM, so paths
to its include files have changed.
This broke the Clang test in tools/build - let's fix it.
