2012-04-18perf annotate: Parse call targets earlierArnaldo Carvalho de Melo1-0/+1
No need to do it everytime the user presses enter/-> on a call instruction.

2012-04-18perf annotate: Disassembler instruction parsingArnaldo Carvalho de Melo1-0/+13
So that at disassembly time we parse targets, etc. Supporting jump instructions initially, call functions are next.

2012-04-16perf annotate: Parse instructionArnaldo Carvalho de Melo1-0/+3
For lines with instructions find the name and operands, breaking those tokens for consumption by the browser.

2012-04-16perf annotate: Rename objdump_line to disasm_lineArnaldo Carvalho de Melo1-6/+5
We want to move away from using 'objdump -dS' as the only disassembler supported.

2011-11-28perf symbols: Add nr_events to symbol_confArnaldo Carvalho de Melo1-3/+2
Since symbol__alloc_hists need it, to avoid passing it around in many functions have it in the symbol_conf struct.

2011-10-07perf annotate browser: Allow navigation to called functionsArnaldo Carvalho de Melo1-1/+1
I.e. when in the annotate TUI window, if Enter is pressed over an assembly line with a 'callq' it will try to open another TUI window with that symbol. This is just a proof of concept and works only on x86_64, more work is needed to support kernel modules, userland, other arches, etc, but should already be useful as-is.

2011-10-07perf browsers: Add live mode to the hists, annotate browsersArnaldo Carvalho de Melo1-2/+5
This allows passing a timer to be run periodically, which will update the hists tree that then gers refreshed on the screen, just like the Live mode (symbol entries, annotation) we already have in 'perf top --tui'. Will be used by the new hist_entry/hists based 'top' tool.

2011-09-29perf: Support setting the disassembler styleAndi Kleen1-0/+2
Add -M option to report/annotate to pass directly to objdump. This allows to use -M intel for intel style disassembler syntax, which is useful for people who are very used to the Intel syntax.

2011-02-22perf top: Live TUI AnnotationArnaldo Carvalho de Melo1-2/+4
Now one has just to press the right key, 'a' or Enter on the main 'perf top --tui' screen to live annotate the symbol under the cursor. The annotate window starts centered on the hottest line (the one with most samples so far) then TAB and shift+TAB can be used to go to the prev/next hot line. Pressing 'H' at any point will center again the screen on the hottest line.

2011-02-08perf annotate: Fix annotate context lines regressionArnaldo Carvalho de Melo1-1/+2
The live annotation done in 'perf top' needs to limit the context before lines that aren't filtered out by the min percent filter, if we don't do that, the screen in a tty often is not enough for showing what is interesting: lines with hits and a few source code lines before it.

2011-02-08perf annotate: Move locking to struct annotationArnaldo Carvalho de Melo1-14/+20
Since we'll need it when implementing the live annotate TUI browser. This also simplifies things a bit by having the list head for the source code to be in the dynamicly allocated part of struct annotation, that way we don't have to pass it around, it can be found from the struct symbol that is passed everywhere.

2011-02-06perf annotate: Separate objdump parsing from actual screen renderingArnaldo Carvalho de Melo1-0/+4
Because in 'perf top' we'll need to parse just once and then, as samples come, render multiple times with evolving counter values.

2011-02-05perf annotate: Support multiple histograms in annotationArnaldo Carvalho de Melo1-5/+24
The perf annotate tool continues aggregating everything on just one histograms, but to support the top model add support for one histogram perf evsel in the evlist.

2011-02-05perf annotate: Move annotate functions to util/Arnaldo Carvalho de Melo1-0/+65
They will be used by perf top, so that we have just one set of routines to do annotation. Rename "struct sym_priv" to "struct annotation", etc, to clarify this code a bit. Rename "struct sym_ext" to "struct source_line", to give it a meaningful name, that clarifies that it is a the result of an addr2line call, that is sorted by percentage one particular source code line appeared in the annotation. And since we're moving things around also rename 'sym_hist->ip' to 'sym_hist->addr' as we want to do data structure annotation at some point.
