[PATCH 0/3] perf tools: Add libdw DWARF post unwind support for ARM64

by Jean Pihet

Adding libdw DWARF post unwind support, which is part of elfutils-devel/libdw-dev package from version 0.158. Also includes the test suite for dwarf unwinding, by adding the arch specific test code and the perf_regs_load function. This series depends on the following kernel patches series: - AARCH64 unwinding support [1], - ARM libdw integration [2], and on the changes from the branch for: - libdw AARCH64 unwinding support [3]. [1] http://www.spinics.net/lists/arm-kernel/msg304483.html [2] http://www.spinics.net/lists/arm-kernel/msg312423.html [3] https://git.fedorahosted.org/cgit/elfutils.git/log/?h=mjw/aarch64-unwind Jean Pihet (3): perf tests: Introduce perf_regs_load function on ARM64 perf tests: Add dwarf unwind test on ARM64 perf tools: Add libdw DWARF post unwind support for ARM64 tools/perf/Makefile.perf | 2 +- tools/perf/arch/arm64/Makefile | 7 ++++ tools/perf/arch/arm64/include/perf_regs.h | 5 +++ tools/perf/arch/arm64/tests/dwarf-unwind.c | 59 ++++++++++++++++++++++++++++++ tools/perf/arch/arm64/tests/regs_load.S | 39 ++++++++++++++++++++ tools/perf/arch/arm64/util/unwind-libdw.c | 53 +++++++++++++++++++++++++++ tools/perf/tests/builtin-test.c | 3 +- tools/perf/tests/tests.h | 3 +- 8 files changed, 168 insertions(+), 3 deletions(-) create mode 100644 tools/perf/arch/arm64/tests/dwarf-unwind.c create mode 100644 tools/perf/arch/arm64/tests/regs_load.S create mode 100644 tools/perf/arch/arm64/util/unwind-libdw.c --- - Rebased on latest acme/perf/core git tree, - Tested on the ARMv8 Foundation emulator. -- 1.7.11.7
