perf tests clang: Fix function name for clang IR test
As stated in tests/llvm-src-base.c, the name of the bpf function should be "bpf_func__SyS_epoll_pwait" but this clang test fails as it tries to lookup "bpf_func__SyS_epoll_wait". Before applying patch: 55: builtin clang support : 55.1: builtin clang compile C source to IR : FAILED! 55.2: builtin clang compile C source to ELF object : Skip After applying patch: 55: builtin clang support : 55.1: builtin clang compile C source to IR : Ok 55.2: builtin clang compile C source to ELF object : Ok Signed-off-by: Sandipan Das <sandipan@linux.vnet.ibm.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Naveen N.
