    Support probing on offline cross-architecture binary by adding getting
    the target machine arch from ELF and choose correct register string for
    the machine.

    Here is an example:
    -----
    $ perf probe --vmlinux=./vmlinux-arm --definition 'do_sys_open $params'
    p:probe/do_sys_open do_sys_open+0 dfd=%r5:s32 filename=%r1:u32 flags=%r6:s32 mode=%r3:u16
    -----

    Here, we can get probe/do_sys_open from above and append it to to the target
    machine's tracing/kprobe_events file in the tracefs mountput, usually
    /sys/kernel/debug/tracing/kprobe_events (or /sys/kernel/tracing/kprobe_events).

    There is a problem in the dwarf-regs.c files for sh, sparc and x86 where
    it is possible to make an out-of-bounds array access when searching for
    register names.

    This patch fixes it by replacing '

  • 5e8c0fb6a   perf build: Add arch x86 objects building ... Browse Code »

    Move the x86 arch objects building under build framework to be included
    in the libperf build object.

    Adding also arch/$(ARCH)/Build files for the rest of the archs. The
    reason for this is that in arch/Build we now do:

    +libperf-y += $(ARCH)/

    which would make the build to fail on other architectures, because the
    build framework requires 'Build' file in nested directories and this
    patch adds it only for x86.

  • 861e10be0   perf tools: Fix build on non-glibc systems due to libio.h absence ... Browse Code »

    Including libio.h causes build failures on uClibc systems (which lack
    libio.h).

    It appears that libio.h was only included to pull in a definition for
    NULL, so it has been replaced by stddef.h.

    On powerpc, libio.h was conditionally included, but could be removed
    completely as it is unneeded. Also, the included of stdlib.h was changed
    to stddef.h (as again, only NULL is needed).
