tools: Copy lib/hweight.c from the kernel sources

2015-07-09T19:29:56Z

Instead of accessing it directly, as it uses EXPORT_SYMBOL, that has no meaning in tools/perf and because we removed the stubs for it, i.e. we removed the tools/include/linux/export.h file. This fixes the build for the detached tarball sources cases and removes one more source of entanglement with the kernel sources.

tools: Copy lib/rbtree.c to tools/lib/

2015-07-06T01:48:21Z

So that we can remove kernel specific stuff we've been stubbing out via a tools/include/linux/export.h that gets removed in this patch and to avoid breakages in the future like the one fixed recently where rcupdate.h started being used in rbtree.h.

tools lib traceevent: Export dynamic symbols used by traceevent plugins

2015-06-08T13:30:31Z

Traceevent plugins need dynamic symbols exported from libtraceevent.a, otherwise a dlopen error will occur during plugins loading. This patch uses dynamic-list-file to export dynamic symbols which will be used in plugins to perf executable. The problem is covered up if feature-libpython is enabled, because PYTHON_EMBED_LDOPTS contains '-Xlinker --export-dynamic' which adds all symbols to the dynamic symbol table. So we should reproduce the problem by setting NO_LIBPYTHON=1.

tools lib traceevent: Install libtraceevent.a into libdir

2015-05-18T15:36:25Z

Before this patch, 'make install' installs libraries into bindir: $ make install DESTDIR=./tree INSTALL trace_plugins INSTALL libtraceevent.a INSTALL libtraceevent.so $ find ./tree ./tree/ ./tree/usr ./tree/usr/local ./tree/usr/local/bin ./tree/usr/local/bin/libtraceevent.a ./tree/usr/local/bin/libtraceevent.so ... /usr/local/lib( or lib64) should be a better place. This patch replaces 'bin' with libdir. For __LP64__ building, libraries are installed to /usr/local/lib64. For other building, to /usr/local/lib instead. After applying this patch: $ make install DESTDIR=./tree INSTALL trace_plugins INSTALL libtraceevent.a INSTALL libtraceevent.so $ find ./tree ./tree ./tree/usr ./tree/usr/local ./tree/usr/local/lib64 ./tree/usr/local/lib64/libtraceevent.a ./tree/usr/local/lib64/traceevent ./tree/usr/local/lib64/traceevent/plugins ./tree/usr/local/lib64/traceevent/plugins/plugin_mac80211.so ./tree/usr/local/lib64/traceevent/plugins/plugin_hrtimer.so ... ./tree/usr/local/lib64/libtraceevent.so Signed-off-by: Wang Nan Acked-by: Jiri Olsa Acked-by: Steven Rostedt Cc: Alexei Starovoitov Cc: Brendan Gregg Cc: Daniel Borkmann Cc: David Ahern Cc: Masami Hiramatsu Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Cc: pi3orama@163.com Cc: Zefan Li Link: http://lkml.kernel.org/r/1431860222-61636-4-git-send-email-wangnan0@huawei.com Signed-off-by: Arnaldo Carvalho de Melo

Where such macro is not present, so just copy its definition from glibc's endian.h and define it if not already.
