perf unwind: Do not put libunwind-{x86,aarch64} in FEATURE_TESTS_BASIC
As it is not normally available on x86_64 not being tested on test-all.c but being in FEATURE_TESTS_BASIC ends up implying that those features are present, which leads to trying to link with those libraries and a build failure now that test-all.c is finally again building successfully: /usr/bin/ld: cannot find -lunwind-x86 /usr/bin/ld: cannot find -lunwind-aarch64 collect2: error: ld returned 1 exit status make[3]: *** [Makefile:199: /tmp/build/perf/plugin_jbd2.so] Error 1 make[3]: *** Waiting for unfinished jobs.... /usr/bin/ld: cannot find -lunwind-x86 /usr/bin/ld: cannot find -lunwind-aarch64 So remove those features from there and explicitely test them. And then move this patch to just before the last one that allows this to be exposed, so that we keep the tree bisectable. With all this in place we get, at this point: $ ldd /tmp/build/perf/feature/test-libunwind.bin linux-vdso.so.1 (0x00007fffa09c6000) libunwind-x86_64.so.8 => /lib64/libunwind-x86_64.so.8 (0x00007fbcf4451000) libunwind.so.8 => /lib64/libunwind.so.8 (0x00007fbcf4435000) liblzma.so.5 => /lib64/liblzma.so.5 (0x00007fbcf440c000) libelf.so.1 => /lib64/libelf.so.1 (0x00007fbcf43f2000) libc.so.6 => /lib64/libc.so.6 (0x00007fbcf422c000) libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007fbcf4211000) /lib64/ld-linux-x86-64.so.2 (0x00007fbcf4491000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00007fbcf41ed000) libz.so.1 => /lib64/libz.so.1 (0x00007fbcf41d3000) $ cat /tmp/build/perf/feature/test-libunwind-x86.make.output test-libunwind-x86.c:2:10: fatal error: libunwind-x86.h: No such file or directory #include <libunwind-x86.h> ^~~~~~~~~~~~~~~~~ compilation terminated. $ cat /tmp/build/perf/feature/test-libunwind-aarch64.make.output test-libunwind-aarch64.c:2:10: fatal error: libunwind-aarch64.h: No such file or directory #include <libunwind-aarch64.h> ^~~~~~~~~~~~~~~~~~~~~ compilation terminated. $ $ ldd ~/bin/perf | grep unwind libunwind-x86_64.so.8 => /lib64/libunwind-x86_64.so.8 (0x00007f5ceb24b000) libunwind.so.8 => /lib64/libunwind.so.8 (0x00007f5ceb22f000) $ Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: He Kuang <hekuang@huawei.com> Cc: Jean Pihet <jean.pihet@linaro.org> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Cc: Will Deacon <will.deacon@arm.com> Link: https://lkml.kernel.org/n/tip-vs6kwqsvwk7oxhs6z9mq87pp@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
