When build with 'make ARCH=x86' and dwarf unwind is on, there is a compiling error: CC /home/wn/perf/arch/x86/util/unwind-libdw.o CC /home/wn/perf/arch/x86/tests/regs_load.o arch/x86/tests/regs_load.S: Assembler messages: arch/x86/tests/regs_load.S:65: Error: operand type mismatch for `push' arch/x86/tests/regs_load.S:72: Error: operand type mismatch for `pop' make[1]: *** [/home/wn/perf/arch/x86/tests/regs_load.o] Error 1 make[1]: INTERNAL: Exiting with 25 jobserver tokens available; should be 24! make: *** [all] Error 2 ... Which is caused by incorrectly undefine macro HAVE_ARCH_X86_64_SUPPORT. 'config/Makefile.arch' tests __x86_64__ only when 'ARCH=x86_64'. However, when building x86_64 kernel, ARCH=x86 is valid and commonly used. Build systems, such as yocto, uses x86_64 compiler with 'ARCH=x86' to build x86_64 perf, which causes mismatching. As __LP64__ is defined for x86_64 as well, we can consolidate the __x86_64__ check to the __LP64__ check and get rid of the IS_X86_64 IMHO. (This patch is made by Namhyung Kim when replying my v1 patch: https://lkml.org/lkml/2015/1/7/17 I modified the code to remove dependency on RAW_ARCH: https://lkml.org/lkml/2015/1/7/865 Namhyung Kim didn't provide his SOB in his original email.

Current EXTLIBS contains -lelf by default and removes it when libelf is not detected.

According to PEP 394 recommendation [1], it's more portable to use python2 rather than plain python to refer python binary version 2. Since there're distros using python3 by default like Arch, and we don't support python3 (yet), it'd be better using python2 explicitly. But older versions (prior to 2.7) seem not to provide python2 but just python. Given that it's only old version, try python2 first and then fallback to python. It'll ensure that it always points to python 2.x. I tested (compiles and perf script runs) with the combinations: 1) python -> python2.x, python-config -> python2.x-config python2 N/A, python2-config N/A 2) python -> python3.x, python-config -> python3.x-config python2 -> python2.x, python2-config -> python2.x-config 3) python -> python2.x, python-config -> python2.x-config python2 -> python2.x, python2-config -> python2.x-config 4) python -> python2.x, python-config -> python2.x-config python2 -> python2.x, python2-config N/A Based on / replaces the patch 2/2 by Namhyung Kim.

Thomas reported that make PYTHON=python2 is not work on some systems. I can reproduce it on my ArchLinux box too. This is because it's overridden by config/feature-checks/Makefile regardless of PYTHON setting. I guess it's a bug slipped into during the feature checking change. Actually, we don't need to check python-config in the feature-checks. We can just pass appropriate FEATURE_CHECK_*FLAGS.

When saving the callchain on Power, the kernel conservatively saves excess entries in the callchain. A few of these entries are needed in some cases but not others. We should use the DWARF debug information to determine when the entries are needed. Eg: the value in the link register (LR) is needed only when it holds the return address of a function. At other times it must be ignored. If the unnecessary entries are not ignored, we end up with duplicate arcs in the call-graphs. Use the DWARF debug information to determine if any callchain entries should be ignored when building call-graphs. Callgraph before the patch: 14.67% 2234 sprintft libc-2.18.so [.] __random | --- __random | |--61.12%-- __random | | | |--97.15%-- rand | | do_my_sprintf | | main | | generic_start_main.isra.0 | | __libc_start_main | | 0x0 | | | --2.85%-- do_my_sprintf | main | generic_start_main.isra.0 | __libc_start_main | 0x0 | --38.88%-- rand | |--94.01%-- rand | do_my_sprintf | main | generic_start_main.isra.0 | __libc_start_main | 0x0 | --5.99%-- do_my_sprintf main generic_start_main.isra.0 __libc_start_main 0x0 Callgraph after the patch: 14.67% 2234 sprintft libc-2.18.so [.] __random | --- __random | |--95.93%-- rand | do_my_sprintf | main | generic_start_main.isra.0 | __libc_start_main | 0x0 | --4.07%-- do_my_sprintf main generic_start_main.isra.0 __libc_start_main 0x0 TODO: For split-debug info objects like glibc, we can only determine the call-frame-address only when both .eh_frame and .debug_info sections are available.

Currently 'make help' message has such hint: use "make prefix=<path> <install target>" to install to a particular path like make prefix=/usr/local install install-doc But this is misleading, when I specify "prefix=/usr/local", it has got no respect at all. This is because that, "DESTDIR" is considered first. In this case, "DESTDIR" has an empty value, so "prefix" is honored. However, "prefix" is unconditionally assigned to $HOME, regardless of what it is set to from command line. So our "prefix" setting got no respect and the actual destination falls back to $HOME. This patch fixes this issue and corrects the help message.

arch/x86/tests/regs_load.S is missing the linker note about the stack requirements, therefore making the linker fall back to an executable stack. As this object gets linked against the final perf binary, it'll needlessly end up with an executable stack. Fix this by adding the appropriate linker note. Also add a global linker flag to prevent future regressions, as suggested by Jiri. This way perf won't get an executable stack even if we fail to add the .GNU-stack linker note to future assembler files. Though, doing so might create regressions the other way around, when (statically) linking against libraries needing an executable stack. But, apparently, regressing in that direction is wanted as it is an indicator of poor code quality -- or just missing linker notes.
