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 ,
- ARM libdw integration ,
and on the changes from the branch for:
- libdw AARCH64 unwinding support .
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
