2018-08-08perf annotate: Switch struct annotation_data::percent to arrayJiri Olsa
So we can hold multiple percent values for annotation line. The first member of this array is current local hits percent value (PERCENT_HITS_LOCAL index), so no functional change is expected. Adding annotation_data__percent function to return requested percent value from struct annotation_data.

2018-08-08perf annotate: Rename struct annotation_line::samples* to data*Jiri Olsa
The name 'samples*' is little confusing because we have nested 'struct sym_hist_entry' under annotation_line struct, which holds 'nr_samples' as well. Also the holding struct name is 'annotation_data' so the 'data' name fits better.

2018-08-08perf annotate: Get rid of annotation__scnprintf_samples_period()Jiri Olsa
We have more current function tto get the title for annotation, which is hists__scnprintf_title. They both have same output as far as the annotation's header line goes. They differ in counting of the nr_samples, hists__scnprintf_title provides more accurate number based on the setup of the symbol_conf.filter_relative variable. Plus it also displays any uid/thread/dso/socket filters/zooms if there are set any, which annotation__scnprintf_samples_period does not.

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.

2018-03-05perf annotate browser: Be more robust when drawing jump arrowsArnaldo Carvalho de Melo
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.

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.
