  perf dso: Fix dso comparison (2020-03-24 10:57:38 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf report/top:

  Jin Yao:

  - Support annotation of unresolved symbols, just using its addresses.

  - Print addr_location.al_addr when finding a map but not a symbol, so
    that we have the address relative to the map which is what objdump
    produces, then we can match the output of perf and objdump for such
    unresolved addresses.

  - Allow sorting by non-group leaders when working with multiple events,
    be it in a explicit group, i.e. an event list surrounded by {} (e.g.
    'perf record -e '{cycles,instructions,cache-misses}', or without,
    using --group in 'perf report', e.g.:

        perf record -e cycles,instructions,cache-misses
	perf report --group --group-sort-idx 1

     That '1' will ask for the output to be sorted by 'instructions', not
     the default 'cycles'.

  - Add hotkeys to interactively resort the output when using multiple
    events, '0', '1', ... '9' to resort by the nth event, just like when
    using --group-sort-idx, as explained above.

perf stat:

  Jin Yao:

  - Align the output for interval aggregation mode.

event parsing:

  Ian Rogers:

  - Fix 3 use after frees found with clang ASAN.

perf tools:

  Jiri Olsa:

  - Unify a bit the build directory output.

perf tests:

  John Garry:

  - Add PMU events tests, checking that JSON files are properly parsed.

perf stat:

  Kajol Jain:

  - Fix printing event names of metric group with multiple events incase of overlapping events.

perf symbols:

  Leo Yan:

  - Consolidate symbol fixup issue.

vendor events AMD:

  Vijay Thakkar:

  - Restrict model detection for zen1 based processors

  - Add Zen2 events.

  - Update Zen1 events to V2.

perf cpumap:

  Christophe JAILLET:

 - Fix snprintf overflow check

DSOs:

  Ravi Bangoria:

  - Fix dso comparison wrt IDs (maj, min, etc), that had made 'perf archive'
    stop working when build-ids were not being collected.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Ubuntu 19.10 is failing when linking against libllvm, which isn't the default,
needs to be investigated, haven't tested with CC=gcc, but should be the same
problem:

+ make ARCH= CROSS_COMPILE= EXTRA_CFLAGS= LIBCLANGLLVM=1 -C /git/linux/tools/perf O=/tmp/build/perf CC=clang

  It builds ok with the default set of options.
