Hi all,
This patchset implements event group view on perf annotate. It's
basically a rebased version and major difference to prior version is
the GTK annotation browser support.
Here goes an example:
$ perf annotate --group --stdio

Pass evsel instead of evidx. This is a preparation for supporting
event group view in annotation and no functional change is intended.

The symbol__parse_objdump_line() parses result of the objdump run but
it's hard to follow if one doesn't know the output format of the
objdump. Add a head comment on the function to help her.

Factor out calculation of histogram of a symbol into
disasm__calc_percent. It'll be used for later changes.

The loop end condition is calculated from next disasm_line or the
symbol size if it's the last disasm_line. But it doesn't need to be
calculated at every iteration. Moving it out of the function can
simplify code a bit. Also the src_line doesn't need to be checked in
every time.

Add --group option to enable event grouping. When enabled, all the
group members information will be shown with the leader so skip
non-leader events.
It only supports --stdio output currently. Later patches will extend
additional features.

The perf_evsel__is_group_event function is for checking whether given
evsel needs event group view support or not. Please note that it's
different to the existing perf_evsel__is_group_leader() which checks
only the given evsel is a leader or a standalone (i.e. non-group)
event regardless of event group feature.

The source_line_percent struct contains percentage value of the symbol
histogram. This is a preparation of event group view change.

Dynamically allocate source_line_percent according to a number of
group members and save nr_pcnt to the struct source_line. This
way we can handle multiple events in a general manner.
However since the size of struct source_line is not fixed anymore,
iterating whole source_line should care about its size.
$ perf annotate --group --stdio --print-line

Make percent field of struct browser_disasm_line an array and
move it to the last. This is a preparation of event group view
feature.

The disasm_line__calc_percent() which was used by annotate browser
code almost duplicates disasm__calc_percent. Let's get rid of the
code duplication.

Dynamically allocate browser_disasm_line according to a number of
group members and save nr_pcnt to the struct. This way we can
handle multiple events in a general manner.

I applied this series minus the TUI enabling one, as it is not working,
so right now my perf/core has --group --stdio and --group --gtk working,
please take a look at --group --tui.
I need to go thru this more thoroughly, as at least one thing caught my
attention, in some cases ->nr_pcnt is used and in others
evsel->nr_members, do we need both?

Thanks, I took a look at the TUI code and found some missing pieces and
bugs. Those code were in the original version but seems to get lost
during the cherry-picking and I tested wrong version. :(

Probably not. I was thought keeping an array and its length together is
better. But it's rather a waste to save the same information to every
date structure so I move it to the struct annotate_browser->nr_events.
For evsel->nr_members, current code sets it only for grouping is enabled
so the individual events will have value of 0. Also it's not pass the
evsel to every function need it. But if you think it should really be
fixed that way I can make the change to pass and use evsel->nr_members.
Anyway, below is a fixed version that could survived my testing.

Subject: [PATCH] perf annotate browser: Support event group view on TUI
Dynamically allocate browser_disasm_line according to a number of
group members. This way we can handle multiple events in a general
manner.

This can be left for later, my point here is that we should try to avoid
the various UIs from diverging too much, i.e. the code for --gtk,
--stdio and --tui should be as close and using the same abstractions as
possible.
> Anyway, below is a fixed version that could survived my testing.
indeed, works, compared the output of --stdio --group with --tui --group
and it matches.
While looking at it I noticed that the stdio output wastes the initial
columns, at some point we may want to make the hist_entry lines match
the TUI ones, so that going back and forth on two xterm tabs shows no
differences.
Anyway, thanks, applied!

perf annotate: Pass evsel instead of evidx on annotation functions
Pass evsel instead of evidx. This is a preparation for supporting event
group view in annotation and no functional change is intended.

perf annotate: Add a comment on the symbol__parse_objdump_line()
The symbol__parse_objdump_line() parses result of the objdump run but
it's hard to follow if one doesn't know the output format of the
objdump. Add a head comment on the function to help her.

perf annotate: Cleanup disasm__calc_percent()
The loop end condition is calculated from next disasm_line or the symbol
size if it's the last disasm_line. But it doesn't need to be calculated
at every iteration. Moving it out of the function can simplify code a
bit. Also the src_line doesn't need to be checked in every time.

Add --group option to enable event grouping. When enabled, all the
group members information will be shown with the leader so skip
non-leader events.
It only supports --stdio output currently. Later patches will extend
additional features.

perf evsel: Introduce perf_evsel__is_group_event() helper
The perf_evsel__is_group_event function is for checking whether given
evsel needs event group view support or not. Please note that it's
different to the existing perf_evsel__is_group_leader() which checks
only the given evsel is a leader or a standalone (i.e. non-group) event
regardless of event group feature.

perf annotate: Support event group view for --print-line
Dynamically allocate source_line_percent according to a number of group
members and save nr_pcnt to the struct source_line. This way we can
handle multiple events in a general manner.
However since the size of struct source_line is not fixed anymore,
iterating whole source_line should care about its size.
$ perf annotate --group --stdio --print-line

perf annotate browser: Make browser_disasm_line->percent an array
Make percent field of struct browser_disasm_line an array and move it to
the last. This is a preparation of event group view feature.

perf annotate browser: Use disasm__calc_percent()
The disasm_line__calc_percent() which was used by annotate browser code
almost duplicates disasm__calc_percent. Let's get rid of the code
duplication.
