First of all, in order to build with clang at all, one must first apply Valentin Obst's build fix for LLVM [1]. Once that is done, then when building with clang, via:
make LLVM=1 -C tools/testing/selftests...the following error occurs:
clang: error: cannot specify -o when generating multiple output files
This is because clang, unlike gcc, won't accept invocations of this form:
clang file1.c header2.hFix this by using selftests/lib.mk facilities for tracking local header file dependencies: add them to LOCAL_HDRS, leaving only the .c files to be passed to the compiler.
