perf tools: Introduce llvm config options
This patch introduces [llvm] config section with 5 options. Following patches will use then to config llvm dynamica compiling. 'llvm-utils.[ch]' is introduced in this patch for holding all llvm/clang related stuffs. Example: [llvm] # Path to clang. If omit, search it from $PATH. clang-path = "/path/to/clang" # Cmdline template. Following line shows its default value. # Environment variable is used to passing options. # # *NOTE*: -D__KERNEL__ MUST appears before $CLANG_OPTIONS, # so user have a chance to use -U__KERNEL__ in $CLANG_OPTIONS # to cancel it. clang-bpf-cmd-template = "$CLANG_EXEC -D__KERNEL__ $CLANG_OPTIONS \ $KERNEL_INC_OPTIONS -Wno-unused-value \ -Wno-pointer-sign -working-directory \ $WORKING_DIR -c $CLANG_SOURCE -target \ bpf -O2 -o -" # Options passed to clang, will be passed to cmdline by # $CLANG_OPTIONS. clang-opt = "-Wno-unused-value -Wno-pointer-sign" # kbuild directory. If not set, use /lib/modules/`uname -r`/build. # If set to "" deliberately, skip kernel header auto-detector. kbuild-dir = "/path/to/kernel/build" # Options passed to 'make' when detecting kernel header options. kbuild-opts = "ARCH=x86_64" Signed-off-by: Wang Nan <wangnan0@huawei.com> Acked-by: Alexei Starovoitov <ast@plumgrid.com> Cc: Brendan Gregg <brendan.d.gregg@gmail.com> Cc: Daniel Borkmann <daniel@iogearbox.net> Cc: David Ahern <dsahern@gmail.com> Cc: He Kuang <hekuang@huawei.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kaixu Xia <xiakaixu@huawei.com> Cc: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Zefan Li <lizefan@huawei.com> Cc: pi3orama@163.com Link: http://lkml.kernel.org/r/1437477214-149684-1-git-send-email-wangnan0@huawei.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
