[PATCH v3 0/4] perf tools: Add support for some spe events and precise ip

Hi Jirka,

Thanks for the feedback. I've made the following changes:

Removed the arm_spe_synth_opts struct and added the new types into
itrace_synth_opts. I could re-use branch but the other ones are new.
And the --trace argument documentation has been updated accordingly.

I've removed the processing of the evlist from perf_evlist__splice_list_tail
and put it in a weak function "auxtrace__preprocess_evlist" that is
only built on Arm.

For the 2 patches about the hang on termination, I have removed them
because I haven't been able to reproduce it and everything is working
ok for me. @Wei Li, are you able to post steps required to reproduce?

Thanks
James
