  perf tests: Add dwarf unwind test for powerpc (2016-09-29 11:18:21 -0300)


perf/core improvements and fixes:

User visible:
-

New features:

- Add support for using symbols in address filters with Intel PT and ARM
  CoreSight (hardware assisted tracing facilities) (Adrian Hunter, Mathieu 
Poirier)

Fixes:

- Fix MMAP event synthesis for pre-existing threads when no hugetlbfs
  mount is in place (Adrian Hunter)

- Don't ignore kernel idle symbols in 'perf script' (Adrian Hunter)

- Assorted Intel PT fixes (Adrian Hunter)

Improvements:

- Fix handling of C++ symbols in 'perf probe' (Masami Hiramatsu)

- Beautify sched_[gs]et_attr return value in 'perf trace' (Arnaldo Carvalho de 
Melo)

Infrastructure:
---

New features:

- Add dwarf unwind 'perf test' for powerpc (Ravi Bangoria)

Fixes:

- Fix error paths in 'perf record' (Adrian Hunter)

Documentation:

- Update documentation info about quipper, a C++ parser for converting
  to/from perf.data/chromium profiling format (Simon Que)

Build Fixes:

  Fix building in 32 bit platform with libbabeltrace (Wang Nan)
