perf hists: Rename hists__fprintf_nr_events to events_stats__fprintf

2013-01-24T19:40:11+00:00

As this function deals exclusively with hists->stats.

Preparatory patch for removing the by now needless session->hists, that
should be just session->stats.

perf hists: Introduce perf_hpp__list for period related columns

2012-12-09T11:46:05+00:00

Adding perf_hpp__list list to register and contain all period related
columns the command is interested in.

This way we get rid of static array holding all possible columns and
enable commands to register their own columns.

It'll be handy for diff command in future to process and display data
for multiple files.

perf diff: Add -F option to display formula for computation

2012-10-05T17:13:36+00:00

Adding -F option to display the formula for specified computation.

This is mainly to facilitate debugging, but can be useful anyway.

perf hists: Introduce struct he_stat

2012-10-04T16:34:22+00:00

The struct he_stat is for separating out statistics data of a hist
entry.  It is required for later changes.

It's just a mechanical change and should have no functional differences.

perf diff: Removing the total_period argument from output code

2012-10-04T16:31:30+00:00

The total_period is available in struct hists data via the 'struct
hist_entry::hists' pointer. There's no need to carry it through the
output code path.

Removing 'struct perf_hpp::total_period' pointer, because it's no longer
needed.

perf tools: Removing hists pair argument from output path

2012-10-04T16:29:45+00:00

The hists pointer is now part of the 'struct hist_entry'.

And since the overhead and baseline columns are split now, there's no
reason to pass it through the output path.

perf hists: Separate overhead and baseline columns

2012-10-04T16:28:49+00:00

Currently the overhead and baseline columns are handled within single
function and the distinction is made by 'baseline hists' pointer passed
by 'struct perf_hpp::ptr'.

Since hists pointer is now part of each hist_entry, it's possible to
locate paired hists pointer directly from the passed struct hist_entry
pointer.

Also separating those 2 columns makes the code more obvious.

perf diff: Refactor diff displacement possition info

2012-10-04T16:27:56+00:00

Moving the position calculation into the diff command, so the position
as prepared inside struct hist_entry data and there's no need to compute
in the output display path.

Removing 'displacement' from struct perf_hpp as it is no longer needed.

perf hists: Handle field separator properly

2012-09-08T16:19:55+00:00

When a field separator is given, the output format doesn't need to be
fancy like aligning to column length, coloring the percent value and so
on.  And since there's a slight difference to normal format, fix it not
to break backward compatibility.
