perf annotate: Fix parsing aarch64 branch instructions after objdump update (2018-08-30 15:51:54 -0300)
----------------------------------------------------------------
perf/urgent fixes:
Kernel:
- Modify breakpoint fixes (Jiri Olsa)
perf annotate:
- Fix parsing aarch64 branch instructions after objdump update (Kim Phillips)
- Fix parsing indirect calls in 'perf annotate' (Martin Liška)
perf probe:
- Ignore SyS symbols irrespective of endianness on PowerPC (Sandipan Das)
perf trace:
- Fix include path for asm-generic/unistd.h on arm64 (Kim Phillips)
Core libraries:
- Fix potential null pointer dereference in perf_evsel__new_idx() (Hisao Tanabe)
- Use fixed size string for comms instead of scanf("%m"), that is
not present in the bionic libc and leads to a crash (Chris Phlipot)
- Fix bad memory access in trace info on 32-bit systems, we were reading
8 bytes from a 4-byte long variable when saving the command line in the
perf.data file. (Chris Phlipot)
Build system:
- Streamline bpf examples and headers installation, clarifying
some install messages. (Arnaldo Carvalho de Melo)

Test results:
The first ones are container (docker) 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.
Test "x86 bp modify" fails because this is a distro kernel that doesn't have
the underlying kernel feature fixed.
