Hi Ingo,
This was ready already before my short vacations, and get things
building on the recently released fedora 27 and make 'perf test' pass
all entries, so please consider pulling,
- Arnaldo
Test results at the end of this message, as usual.
The following changes since commit 34c9ca37aaec2e307b837bb099d3b44f0ea04ddc:
tooling/headers: Synchronize updated s390 and x86 UAPI headers (2017-12-06 22:45:24 +0100)

x86/asm: Allow again using asm.h when building for the 'bpf' clang target (2017-12-15 12:30:16 -0300)
----------------------------------------------------------------
perf/urgent fixes:
- Fix up build in hardened environments, such as fedora 27 (Jiri Olsa)
- Do not include header files from the kernel sources for the s/390 arch,
fixing the detached tarball building (Arnaldo Carvalho de Melo)
- Allow again using asm.h when building for the 'bpf' clang target,
guarding x86 specific bits under ifndef __BPF__ (Arnaldo Carvalho de Melo)
- Generate correct debug information for inlined code when generating
ELF images for JITted java programs (Ben Gainey)

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.
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.

Using the shell function for perl CFLAGS retrieval instead of back
quotes (``). Both execute shell with the command, but the latter is more
explicit and seems to be the preferred way.
Also we don't have any other use of the back quotes in perf Makefiles.

On Fedora systems the perl and python CFLAGS/LDFLAGS include the
hardened specs from redhat-rpm-config package. We apply them only for
perl/python objects, which makes them not compatible with the rest of
the objects and the build fails with:
/usr/bin/ld: perf-in.o: relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -f
+PIC
/usr/bin/ld: libperf.a(libperf-in.o): relocation R_X86_64_32S against `.text' can not be used when making a shared object; recompile w
+ith -fPIC
/usr/bin/ld: final link failed: Nonrepresentable section on output
collect2: error: ld returned 1 exit status
make[2]: *** [Makefile.perf:507: perf] Error 1
make[1]: *** [Makefile.perf:210: sub-make] Error 2
make: *** [Makefile:69: all] Error 2
Mainly it's caused by perl/python objects being compiled with:
-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1
which prevent the final link impossible, because it will check
for 'proper' objects with following option:
-specs=/usr/lib/rpm/redhat/redhat-hardened-ld

tools/perf/jvmti is broken in so far as it generates incorrect debug
information. Specifically it attributes all debug lines to the original
method being output even in the case that some code is being inlined
from elsewhere. This patch fixes the issue.
To test (from within linux/tools/perf):
export JDIR=/usr/lib/jvm/java-8-openjdk-amd64/
make
cat << __EOF > Test.java
public class Test
{
private StringBuilder b = new StringBuilder();
private void loop(int i, String... args)

Before this patch, Test.java line numbers get reported that are greater
than the number of lines in the Test.java file. They come from the
source file of the inlined function, e.g. java/lang/String.java:1085.
For further validation one can examine those lines in the JDK source
distribution and confirm that they map to inlined functions called by
Test.java.
After this patch, the filename of the inlined function is output
rather than the incorrect original source filename.

From: Arnaldo Carvalho de Melo <acme@redhat.com>
Long ago we decided to be verbotten including files in the kernel git
sources from tools/ living source code, to avoid disturbing kernel
development (and perf's and other tools/) when, say, a kernel hacker
adds something, tests everything but tools/ and have tools/ build
broken.
This got broken recently by s/390, fix it by copying
arch/s390/include/uapi/asm/perf_regs.h to tools/arch/s390/include/uapi/asm/,
making this one be used by means of <asm/perf_regs.h> and updating
tools/perf/check_headers.sh to make sure we are notified when the
original changes, so that we can check if anything is needed on the
tooling side.
This would have been caught by the 'tarkpg' test entry in:
$ make -C tools/perf build-test
When run on a s/390 build system or container.

Up to f5caf621ee35 ("x86/asm: Fix inline asm call constraints for Clang")
we were able to use x86 headers to build to the 'bpf' clang target, as
done by the BPF code in tools/perf/.
With that commit, we ended up with following failure for 'perf test LLVM', this
is because "clang ... -target bpf ..." fails since 4.0 does not have bpf inline
asm support and 6.0 does not recognize the register 'esp', fix it by guarding
that part with an #ifndef __BPF__, that is defined by clang when building to
the "bpf" target.

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.

Hi Ingo,
Please consider pulling, just to get the build without warnings
and finishing successfully in all my test environments,

perf tools: Fix the build on the alpine:edge distro (2018-07-30 13:15:03 -0300)
----------------------------------------------------------------
perf/urgent fixes: (Arnaldo Carvalho de Melo)
- Update the tools copy of several files, including perf_event.h,
powerpc's asm/unistd.h (new io_pgetevents syscall), bpf.h and
x86's memcpy_64.s (used in 'perf bench mem'), silencing the
respective warnings during the perf tools build.
- Fix the build on the alpine:edge distro.

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.

perf record: Use unmapped IP for inline callchain cursors (2018-10-05 11:18:09 -0300)
----------------------------------------------------------------
perf/urgent fixes:
- Fix the build on Clear Linux, coping with redundant declarations of
function prototypes in python3 header files by adding
-Wno-redundant-decls to build with PYTHON=python3 (Arnaldo Carvalho de Melo)
- Fixes for processing inline frames in backtraces using DWARF based
unwinding (Milian Wolff)
- Cope with bad DWARF info for function names for inline frames,not
trying to demangle this symbol. Problem reported with rust but
reproduced as well with C++. Problem reported to the libbpf
maintainers (Milian Wolff)
- Fix python export to postgresql and sqlite code (Adrian Hunter)
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

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.
The Clear Linux container is building with NO_CLANG=1, the problem preventing
its use when building for python3 has been identified and the next builds will
build in ClearLinux with both gcc and clang. This time around only gcc was
used.
