perf tools: Make flex/bison calls honour V=1 (2015-05-14 19:27:47 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Add --range option to show a variable's location range in 'perf probe',
helping in collecting variables in probes when there is a mismatch
between assembly and source code (He Kuang)
- Show better error message when failed to find variable in 'perf probe' (He Kuang)
- Fix 'perf report --thread' handling and document it better (Namhyung Kim)
Infrastructure:
- Fix to get negative exit codes in 'perf test' test routines (He Kuang)
- Make flex/bison calls honour V=1 (Jiri Olsa)
- Ignore tail calls to probed functions in 'perf probe' (Naveen N. Rao)
- Fix refcount expectations in map_group share 'perf test' (Arnaldo Carvalho de Melo)
Build Fixes:
- Fix 'perf kmem' build due to compiler thinking uninitialized var is
being accessed (Arnaldo Carvalho de Melo)
- Provide le16toh if not defined, to fix the libtraceevent build on
older distros (Arnaldo Carvalho de Melo)
- Fix 'perf trace' build on older distros by providing some CLOEXEC, NONBLOCK
defines (Arnaldo Carvalho de Melo)
Signed-off-by: Arnaldo Carvalho de Melo <acme@...hat.com>
----------------------------------------------------------------
Arnaldo Carvalho de Melo (6):
perf kmem: Fix compiler warning about may be accessing uninitialized variable
perf tests: Show refcounting broken expectations in thread-mg-share test
perf machine: No need to keep a refcnt for last_match
perf tests: Fix map_groups refcount test
tools lib traceevent: Provide le16toh define for older systems
perf trace: Fix the build on older distros
He Kuang (5):
perf trace: Removed duplicated NULL test
perf probe: Remove length limitation for showing available variables
perf probe: Add --range option to show a variable's location range
perf probe: Show better error message when failed to find variable
perf tests: Fix to get negative exit codes
Jiri Olsa (1):
perf tools: Make flex/bison calls honour V=1
Namhyung Kim (4):
perf tools: Document relation of per-thread event count feature
perf report: Force tty output if -T/--thread option is given
perf report: Do not restrict -T option by other options
perf report: Fix some option handling on --stdio
Naveen N. Rao (1):
perf probe: Ignore tail calls to probed functions
