Hello,
This is a new attempt to implement cumulative hist period report.
This work begins from Arun's SORT_INCLUSIVE patch [1] but I completely
rewrote it from scratch.
While testing this patch series, we found error messages which look like
this:
Out of bounds address found:
Addr: 10370
DSO: /usr/local/lib/libgcc_s.so.1 d
Map: 7f1b0c953000-7f1b0c968000
Symbol: 102d0-102e9 g _Unwind_DeleteException

Kernel: 3.10.23+

Not all samples will be on the annotation output.

I first suspected it to be caused by this patch series, but I'm able to
reproduce without these patches as of this commit:
a51e87c perf tools: Remove unused simple_strtoul() function
gdb attributes 0x10370 to a different/known symbol.
(gdb) x /i 0x10370
0x10370 <get_cie_encoding+160>: cmp $0x4c,%dl
Is this known? Could this possibly be caused by stale histogram entries
from unmapped/remapped shared libs?
