To simplify the passing of arguments, the --stdio2 code will have to set
all the fields with operations printing to stdout.

We pass some more callbacks and all of annotate_browser__write() seems
to be free of TUI code (except for some arrow constants, will fix).

For the --tui and --stdio2 cases using callbacks for print() and
set_percent_color() end up being the easiest path, real GUI remains as
an exercise.

That does all the extended boilerplate the TUI browser did, leaving the
symbol__annotate() function to be used by the old --stdio output mode.
Now the upcoming --stdio2 output mode should just use this one to set
things up.

For the TUI, that is interactive, its interesting to have a
configuration that one can go on changing and then when moving from one
symbol annotation to another symbol, the options set while browsing the
first symbol to be kept.
But since we're trying to make this code reusable by a --stdio
formatter, we better have a pointer in struct annotation and in the TUI
case set it to the global, but use something else for other cases, such
as --stdio2.

This is to pave the way to have more functions shared between TUI, stdio
and the upcoming stdio2 formatting, that will use the __scnprintf
functions used by --tui in a --stdio fashion.
This partially addresses the comments added in cset 30e863bb6f70 ("perf
annotate: Compute IPC and basic block cycles"):
/*
* This should probably be in util/annotate.c to share with the tty
* annotate, but right now we need the per byte offsets arrays,
* which are only here.
*/
The following patches will address the rest.

This will be useful when making parts of the TUI browser generic enough
to be used for a new stdio mode, available even when the TUI is not
built in, for explicit user decision or when the necessary library devel
files, for the slang library currently, are not available in the build
system.

When recently using 'perf report --stat' it was not clear to me from the
output whether a particular statistics field (LOST_SAMPLES) was not
present, or just zero:
fomalhaut:~> perf report --stat
Aggregated stats:
TOTAL events: 495984
MMAP events: 85
COMM events: 3389
EXIT events: 1605
THROTTLE events: 2
UNTHROTTLE events: 2
FORK events: 3377
SAMPLE events: 472629
MMAP2 events: 14753
FINISHED_ROUND events: 139
THREAD_MAP events: 1
CPU_MAP events: 1
TIME_CONV events: 1
I had to check the output several times to ascertain that I'm not
misreading the output, that the field didn't change and that I didn't
misremember the name. In fact I had to look into the perf source to make
sure that zero fields are indeed not shown.
With the patch applied:
fomalhaut:~> perf report --stat
Aggregated stats:
TOTAL events: 495984
MMAP events: 85
LOST events: 0
COMM events: 3389
EXIT events: 1605
THROTTLE events: 2
UNTHROTTLE events: 2
FORK events: 3377
READ events: 0
SAMPLE events: 472629
MMAP2 events: 14753
AUX events: 0
ITRACE_START events: 0
LOST_SAMPLES events: 0
SWITCH events: 0
SWITCH_CPU_WIDE events: 0
NAMESPACES events: 0
ATTR events: 0
EVENT_TYPE events: 0
TRACING_DATA events: 0
BUILD_ID events: 0
FINISHED_ROUND events: 139
ID_INDEX events: 0
AUXTRACE_INFO events: 0
AUXTRACE events: 0
AUXTRACE_ERROR events: 0
THREAD_MAP events: 1
CPU_MAP events: 1
STAT_CONFIG events: 0
STAT events: 0
STAT_ROUND events: 0
EVENT_UPDATE events: 0
TIME_CONV events: 1
FEATURE events: 0
It's pretty clear at a glance that LOST_SAMPLES is present but zero.
The original output can still be gotten via:
fomalhaut:~> perf report --stat | grep -vw 0
Aggregated stats:
TOTAL events: 495984
MMAP events: 85
COMM events: 3389
EXIT events: 1605
THROTTLE events: 2
UNTHROTTLE events: 2
FORK events: 3377
SAMPLE events: 472629
MMAP2 events: 14753
FINISHED_ROUND events: 139
THREAD_MAP events: 1
CPU_MAP events: 1
TIME_CONV events: 1
So I don't think there's any real loss in functionality.

This first happened with a gcc function, _cpp_lex_token, that has the
usual jumps:
│1159e6c: ↓ jne 115aa32 <_cpp_lex_token@@Base+0xf92>
I.e. jumps to a label inside that function (_cpp_lex_token), and those
works, but also this kind:
│1159e8b: ↓ jne c469be <cpp_named_operator2name@@Base+0xa72>
I.e. jumps to another function, outside _cpp_lex_token, which are not
being correctly handled generating as a side effect references to
ab->offset[] entries that are set to NULL, so to make this code more
robust, check that here.
A proper fix for will be put in place, looking at the function name
right after the '<' token and probably treating this like a 'call'
instruction.
For now just don't draw the arrow.

The jump arrow in above example is not correct. It should add the
width of IPC and Cycle.
With this patch, the result is:
Percent│ IPC Cycle

1.37 │0.48 1 ┌──je 82
│ │ x += x / y + y / x;
0.00 │0.48 1310 │ movsd (%rsp),%xmm0

28.21 │0.48 17 ↑ jne 38
Committer notes:
Please note that only from LBRv5 (according to Jiri) onwards, i.e. >=
Skylake is that we'll have the cycles counts in each branch record
entry, so to see the Cycles and IPC columns, and be able to test this
patch, one need a capable hardware.
While applying this I first tested it on a Broadwell class machine and
couldn't get those columns, will add code to the annotate browser to
warn the user about that, i.e. you have branch records, but no cycles,
use a more recent hardware to get the cycles and IPC columns.

For overwrite mode, the ringbuffer will be paused. The event lost is

Use struct annotation_line as a browser::selection.
We want to be able to use the annotate_browser for all sorts of source
data, so it needs to be able to work over the generic struct
annotation_line.

Rename disasm_line__browser function to browser_line, because the browser got
generic and is no longer disasm specific.

Rename struct browser_disasm_line to browser_line, because the browser
operates now on generic lines and no longer on disasm lines.

We now keep samples_nr in struct annotation_line, so there's no need to
pass nr_events to disasm_rb_tree__insert function.

We now carry the data in 'struct annotation_line', so using it instead
of samples from 'struct browser_disasm_line' and removing it and its
setup.

annotate_browser__calc_percent()
Remove disasm__calc_percent() from annotate_browser__calc_percent(),
because we already have the data calculated in struct annotation_line.

Changing the way the annotation lines are allocated and adding
annotation_line__(new|delete) functions to deal with this.
Before the allocation schema was as follows:
-----------------------------------------------------------
struct disasm_line | struct annotation_line | private space
-----------------------------------------------------------
Where the private space is used in TUI code to store computed
annotation data for events. The stdio code computes the data
on the fly.
The goal is to compute and store annotation line's data directly
in the struct annotation_line itself, so this patch changes the
line allocation schema as follows:
------------------------------------------------------------
privsize space | struct disasm_line | struct annotation_line
------------------------------------------------------------
Moving struct annotation_line to the end, because in following
changes we will move here the non-fixed length event's data.

Move rb_node to struct annotation_line to make struct annotation_line
the rb tree node for sorted lines used in both stdio and TUI code.
This way we can unite the sorted lines lines codes for both TUI and
stdio in the following patches.
