Add basic clang support in clang.cpp and test__clang() testcase. The first testcase checks if builtin clang is able to generate LLVM IR. tests/clang.c is a proxy. Real testcase resides in utils/c++/clang-test.cpp in c++ and exports C interface to perf test subsystem. Test result: $ perf test -v clang 51: builtin clang support : 51.1: Test builtin clang compile C source to IR : --- start --- test child forked, pid 13215 test child finished with 0 ---- end ---- Test builtin clang support subtest 0: Ok Committer note: Make sure you've enabled CLANG and LLVM builtin support by setting the LIBCLANGLLVM variable on the make command line, e.g.: make LIBCLANGLLVM=1 O=/tmp/build/perf -C tools/perf install-bin Otherwise you'll get this when trying to do the 'perf test' call above: # perf test clang 51: builtin clang support : Skip (not compiled in) # Signed-off-by: Wang Nan <wangnan0@huawei.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexei Starovoitov <ast@fb.com> Cc: He Kuang <hekuang@huawei.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Joe Stringer <joe@ovn.org> Cc: Zefan Li <lizefan@huawei.com> Cc: pi3orama@163.com Link: http://lkml.kernel.org/r/20161126070354.141764-11-wangnan0@huawei.com [ Removed "Test" from descriptions, redundant and already removed from all the other entries ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
