2021-09-18perf annotate: Fix fused instr logic for assembly functionsRavi Bangoria
Some x86 microarchitectures fuse a subset of cmp/test/ALU instructions with branch instructions, and thus perf annotate highlight such valid pairs as fused. When annotated with source, perf uses struct disasm_line to contain either source or instruction line from objdump output. Usually, a C statement generates multiple instructions which include such cmp/test/ALU + branch instruction pairs. But in case of assembly function, each individual assembly source line generate one instruction. The 'perf annotate' instruction fusion logic assumes the previous disasm_line as the previous instruction line, which is wrong because, for assembly function, previous disasm_line contains source line. And thus perf fails to highlight valid fused instruction pairs for assembly functions. Fix it by searching backward until we find an instruction line and consider that disasm_line as fused with current branch instruction.

2021-08-03perf annotate: Re-add annotate_warned functionalityJames Clark
Setting annotate_warned to true on errors was removed in commit ee51d851392e ("perf annotate: Introduce strerror for handling symbol__disassemble() errors") which means when 'perf annotate --skip-missing' is used warnings are shown multiple times for the same DSO. Setting this again restores the original behavior of only one warning each.

2021-07-07perf annotate: Fix 's' on source line when disasm is emptyRiccardo Mancini
If the disasm is empty, 's' should fail. Instead it seemingly works, hiding the empty lines and causing an assertion error on the next time annotate is called (from within perf report). The problem is caused by a buffer overflow, caused by a wrong exit condition in annotate_browser__find_next_asm_line, which checks browser->b.top instead of browser->b.entries. This patch fixes the issue, making annotate_browser__toggle_source fail if the disasm is empty (nothing happens to the user).

2021-07-01perf annotate: Allow 's' on source code linesRiccardo Mancini
In perf annotate, when 's' is pressed on a line containing source code, it shows the message "Only available for assembly lines". This patch gets rid of the error, moving the cursr to the next available asm line (or the closest previous one if no asm line is found moving forwards), before hiding source code lines. Changes in v2: - handle case of no asm line found in annotate_browser__find_next_asm_line by returning NULL and handling error in caller.

2020-02-27perf annotate: Fix --show-nr-samples for tui/stdio2Ravi Bangoria
perf annotate --show-nr-samples does not really show number of samples. The reason is we have two separate variables for the same purpose. One is in symbol_conf.show_nr_samples and another is annotation_options.show_nr_samples. We save command line option in symbol_conf.show_nr_samples but uses annotation_option.show_nr_samples while rendering tui/stdio2 browser. Though, we copy symbol_conf.show_nr_samples to annotation__default_options.show_nr_samples but that is not really effective as we don't use annotation__default_options once we copy default options to dynamic variable annotate.opts in cmd_annotate(). Instead of all these complication, keep only one variable and use it all over. symbol_conf.show_nr_samples is used by perf report/top as well. So let's kill annotation_options.show_nr_samples. On a side note, I've kept annotation_options.show_nr_samples definition because it's still used by perf-config code. Follow up patch to fix perf-config for annotate will remove annotation_options.show_nr_samples.

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.
