Merge tag 'perf-core-for-mingo-4.11-20170215' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/core clang fixes from Arnaldo Carvalho de Melo:
Changes to make tools/{perf,lib/{bpf,traceevent,api}} build with
CC=clang, to, for instance, take advantage of warnings (Arnaldo Carvalho de Melo):
- Conditionally request some warning options not available on clang
- Set the maximum optimization level to -O3 when using CC=clang, leave
the previous setting of -O6 otherwise.
- Make it an error to pass a signed value to OPTION_UINTEGER, so that
we can remove abs(unsigned int) calls in 'perf bench futex'.
- Make sure dprintf() is not defined before using that name in 'perf bench numa'
- Avoid using field after variable sized type, its a GNU extension, use
equivalent code.
- Fix some bugs where some variables could be used unitialized,
something not caught by gcc.
- Fix some spots where we were testing struct->array[] members against
NULL, it will always evaluate to 'true'.
- Add missing parse_events_error() prototype in the bison file.
There are still one problem when trying to build the python support, but
this are the 'size' outputs for 'make -C tools/perf NO_LIBPYTHON' for
gcc and clang builds:
