Subject[PATCH v4 0/6] Fix missing leaf-function callers when recording
Date
(This cset applies on top of [1])

Call-graphs on ARM64 using the option "--call-grah fp" are missing the
callers of the leaf functions. See [PATCH 6/6] for a before and after
after example using this cset.

Changes since v3
- Only record LR register instead of all registers in [PATCH 1/6].
- Introduce [PATCH 5/6] to refactor the SAMPL_REG macro.
- Fix compilation issues on different platforms.

Alexandre Truong (5):
perf tools: record ARM64 LR register automatically
perf tools: add a mechanism to inject stack frames
perf tools: Refactor script__setup_sample_type()
perf tools: enable dwarf_callchain_users on arm64
perf tools: determine if LR is the return address

German Gomez (1):
perf tools: Refactor SMPL_REG macro in perf_regs.h
