-Subject: [PATCH 3/3] Fix DynamicLibrary to build with musl libc
-
-stdin/out/err is part of the libc and not the kernel so we check for the
-specific libc that does the unexpected instead of linux.
-
-This is needed for making it build with musl libc.

user/clang/0008-Fix-ClangConfig-cmake-LLVM-path.patch

+From: Adeel <adeelbm@outlook.com>
+Date: Sun, 6 May 2018 10:22:00 +0200
+Subject: [PATCH] Fix ClangConfig.cmake to look for LLVM-Config.cmake in correct location
+
+This results in the following change in the generated ClangConfig.cmake:
+
+     find_package(LLVM REQUIRED CONFIG
+    -             HINTS "${CLANG_INSTALL_PREFIX}/lib/cmake/llvm")
+    +             HINTS "/usr/lib/llvm5/lib/cmake/llvm")
+
+This is needed e.g. for building lldb.
+
+See https://github.com/alpinelinux/aports/pull/2342 for more information.
