perf test: Enhance the LLVM tests: add kbuild test
This patch adds a kbuild testcase to check whether kernel headers can be correctly found. For example: # mv /lib/modules/4.3.0-rc5{,.bak} # perf test LLVM 38: Test LLVM searching and compiling : Skip # perf test -v LLVM ... <stdin>:11:10: fatal error: 'uapi/linux/fs.h' file not found #include <uapi/linux/fs.h> ^ 1 error generated. ERROR: unable to compile - Hint: Check error message shown above. Hint: You can also pre-compile it into .o using: clang -target bpf -O2 -c - with proper -I and -D options. Failed to compile test case: 'Test kbuild searching' test child finished with -2 Signed-off-by: Wang Nan <wangnan0@huawei.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Zefan Li <lizefan@huawei.com> Cc: pi3orama@163.com Link: http://lkml.kernel.org/r/1446817783-86722-7-git-send-email-wangnan0@huawei.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
