tools build: Add feature detection for g++ (2016-10-05 19:59:35 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
- Intel PT timestamp fixes (Adrian Hunter)
- Fix Intel JSON fixed counter conversions (Andi Kleen)
- Sync memcpy, cpufeatures and bpf headers with the kernel (Arnaldo Carvalho de Melo)
- Add some more tool tips (Donghyun Kim, Kim SeonYoung, Nambong Ha)
- Fix libtraceevent's kbuffer_read_at_offset() handling of offsets before or
equal the first event (Namhyung Kim)
- Fix uretprobe probe placement on ppc64le (Ravi Bangoria)
- Support building C++ source files and add feature detection for g++,
prep work for supporting a builtin clang/llvm, to remove the need for having
that toolchain installed to automagically build BPF scriptlets that then
gets uploaded to the kernel via sys_bpf() (Wang Nan)

#, v4.3+, Arnaldo Carvalho de Melo
From: Adrian Hunter <adrian.hunter@intel.com>
In cycle-accurate mode, timestamps can be calculated from CYC packets.
The decoder also estimates timestamps based on the number of
instructions since the last timestamp. For that to work in
cycle-accurate mode, the instruction count needs to be reset to zero
when a timestamp is calculated from a CYC packet, but that wasn't
happening, so fix it.

#, v4.3+, Arnaldo Carvalho de Melo
From: Adrian Hunter <adrian.hunter@intel.com>
The MTC packet provides a 8-bit slice of CTC which is related to TSC by
the TMA packet, however the TMA packet only provides the lower 16 bits
of CTC. If mtc_shift > 8 then some of the MTC bits are not in the CTC
provided by the TMA packet. Fix-up the last_mtc calculated from the TMA
packet by copying the missing bits from the current MTC assuming the
least difference between the two, and that the current MTC comes after
last_mtc.
