perf clang: Add builtin clang support ant test case
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)
