perf symbols: Remove symbol_filter_t machinery

2016-09-05T14:14:50+00:00

We're not using it anymore, few users were, but we really could do
without it, simplify lots of functions by removing it.

perf annotate: Introduce strerror for handling symbol__disassemble() errors

2016-08-01T21:18:16+00:00

We were just using pr_error() which makes it difficult for non stdio UIs
to provide errors using its widgets, as they need to somehow catch what
was passed to pr_error().

Fix it by introducing a __strerror() interface like the ones used
elsewhere, for instance target__strerror().

This is just the initial step, more work will be done, but first some
error handling bugs noticed while working on this need to be dealt with.

perf annotate: Rename symbolannotate() to symboldisassemble()

2016-08-01T20:06:46+00:00

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.

perf annotate: Generalize handling of 'ret' instructions

2016-06-27T17:25:05+00:00

Introduce helper to detect 'ret' instructions and use the same in the TUI.
A helper is needed since some architectures such as powerpc have more
than one return instruction.

perf config: Move config declarations from util/cache.h to util/config.h

2016-06-23T11:51:41+00:00

Lately util/config.h has been added but util/cache.h has declarations of
functions and a global variable for config features.

To manage codes about configuration at one spot, move them to
util/config.h and let source files that need config features include
config.h And if the source files that included previous cache.h need
only config.h, remove including cache.h.

perf annotate: Rename 'colors.code' to 'colors.jump_arrows'

2016-01-26T14:52:46+00:00

USe 'jump_arrows' config name instead of 'code' on 'colors' section.
'colors.code' config is only for jump arrows on assembly code listings
i.e.

    │     ┌──jmp    1333
    │     │  xchg   %ax,%ax
    │     │  mov    %r15,%r10
    │     └─→cmp    %r15,%r14

But this config name seems unfit.

 'jump_arrows' is more descriptive than 'code'.

perf annotate: Don't die() when finding an invalid config option

2015-10-22T21:10:52+00:00

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.

That die() needs to die, tho :-)

perf annotate: Fix 'annotate.use_offset' config variable usage

2015-10-22T19:34:29+00:00

The annotate__configs should be sorted so that it can use bsearch(3).

However commit 0c4a5bcea460 ("perf annotate: Display total number of
samples with --show-total-period") added a new config item at the end.
This resulted in the 'annotate.use_offset' config variable cannot be
found and perf terminated like below:

They were repurposed for horizontal scrolling, so use just ENTER/ESC in
