This function will not annotate anything, it will just disassembly the given map->dso and symbol. It currently does this by parsing the output of 'objdump --disassemble', but this could conceivably be done using a library or an offshot of the kernel's instruction decoder (arch/x86/lib/inat.c), etc. Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/n/tip-2xpfl4bfnrd6x584b390qok7@git.kernel.orgSigned-off-by: NArnaldo Carvalho de Melo <acme@redhat.com>

The perf_config() infrastructure we inherited from git calls die() when the provided config callback returns -1, meaning some key in a config section is unexpected, that seems ok for a stdio based tool, but in --tui we end up messing up the output, so just tell the user about the error, wait for a keystroke and return 0, being more resilient and proceeding with what we managed to parse.

Compute the IPC and the basic block cycles for the annotate display. IPC is computed by counting the instructions, and then dividing the accounted cycles by that count. The actual IPC computation can only be done at annotate time, because we need to parse the objdump output first to know the number of instructions in the basic block. The cycles/IPC are also put into the perf function annotation so that the display code can show them. Again basic block overlaps are not handled, with the longest winning, but there are some heuristics to hide the IPC when the longest is not the most common. v2: Compute IPC correctly.

It was inconvenient that perf cannot be quit with SIGINT during processing samples on TUI especially for large data files. This was because the first argument of SLang_init_tty(), abort_char, being 0. The manual says it's the ascii value of the control character that will be used to generate the interrupt signal [1]. Passing -1 means to use the default value (Ctrl-C). However, after processing samples, Ctrl-C was used to in other cases as well - like stepping back from annotate. So recover the original behavior after processing.

With srcline key/sort'ing it's useful to have line numbers in the annotate window. This patch implements this. Use objdump -l to request the line numbers and save them in the line structure. Then the browser displays them for source lines. The line numbers are not displayed by default, but can be toggled on with 'k' There is one unfortunate problem with this setup. For lines not containing source and which are outside functions objdump -l reports line numbers off by a few: it always reports the first line number in the next function even for lines that are outside the function. I haven't found a nice way to detect/correct this. Probably objdump has to be fixed. See https://sourceware.org/bugzilla/show_bug.cgi?id=16433 The line numbers are still useful even with these problems, as most are correct and the ones which are not are nearby. v2: Fix help text. Handle (discriminator...) output in objdump. Left align the line numbers.

Currently various hist browser functions receive 3 arguments for refreshing histogram but only used from a few places. Also it's only for perf top command so that it can be NULL for other (and probably most) cases. Pack them into a struct in order to reduce number of those unused arguments. This is a mechanical change and does not intend a functional change.

Integrate the script browser into annotation, users can press function key 'r' to list all perf scripts and select one of them to run that script, the output will be shown in a separate browser.

perf defines both __used and __unused variables to use for marking unused variables. The variable __used is defined to __attribute__((__unused__)), which contradicts the kernel definition to __attribute__((__used__)) for new gcc versions. On Android, __used is also defined in system headers and this leads to warnings like: warning: '__used__' attribute ignored __unused is not defined in the kernel and is not a standard definition. If __unused is included everywhere instead of __used, this leads to conflicts with glibc headers, since glibc has a variables with this name in its headers. The best approach is to use __maybe_unused, the definition used in the kernel for __attribute__((unused)). In this way there is only one definition in perf sources (instead of 2 definitions that point to the same thing: __used and __unused) and it works on both Linux and Android. This patch simply replaces all instances of __used and __unused with __maybe_unused.

So that when navigating to another function from a call site or when going to another annotation browser thru the main report/top browser the options (hide source code, jump arrows, jumpy lines, etc) remains the last ones selected.

When hide_src_view is true we can't use browser_disasm_line->idx, that takes into account also non asm lines, we must use browser_disasm_line->idx_asm instead, otherwise we may end up with an index after the number of entries, oops, fix it.
