[RFC v2 0/4] perf tools: Add support for some spe events and precise ip

[Tan Xiaojun]

After the commit ffd3d18c20b8 ("perf tools: Add ARM Statistical
Profiling Extensions (SPE) support") is merged, "perf record" and
"perf report --dump-raw-trace" have been supported. However, the
raw data that is dumped cannot be used without parsing.

This patchset is to improve the "perf report" support for spe, and
further process the data. Currently, support for the three events
of llc-miss, tlb-miss, and branch-miss is added.

And through the spe to support the precise ip of the branch-misses
event, like "branch-misses:pp".

v1->v2:
Some cleanup and bugfix fixes were made, and support for the precise
ip of branch-misses was added. Thanks for the suggestions of Jeremy
and James.

Tan Xiaojun (4):
  perf tools: Move arm-spe-pkt-decoder.h/c to the new dir
  perf tools: Add support for "report" for some spe events
  perf report: Add --spe options for arm-spe
  perf tools: Support "branch-misses:pp" on arm64
