the speed up is for DWARF unwind report, which is not yet
supported on s390x perf.. still it should compile ;-)
I'll try to get some s

Hi Jiri,

I'm not familiar with the code base, so probably silly questions: Where
does the speed up come from?
Caching registers value into an array. Got about 4% speed up
of perf_reg_value function for report command processing
dwarf unwind stacks.
Output from report over 1.5 GB data with DWARF unwind stacks:
(TODO fix perf diff)
current code:
6.81% perf.old perf.old [.] perf_reg
