H A Dparse-branch-options.cdiff 5b68164d Thu May 14 15:10:00 MDT 2015 Stephane Eranian <eranian@google.com> perf record: Add support for sampling indirect jumps

This patch adds a new branch sampling type support for indirect jumps:

perf record -j ind_jmp .......

It enables analysis of indirect jumps targets. It requires kernel and
possibly hardware support to operate correctly.

H A Dperf_event.hdiff c9fdfa14 Thu May 14 15:09:58 MDT 2015 Stephane Eranian <eranian@google.com> perf: add new PERF_SAMPLE_BRANCH_IND_JUMP branch sample type

This patch adds a new branch_sample_type flag to enable
filtering branch sampling to indirect jumps. The support
is subject to hardware or kernel software support on each
architecture.

Filtering on indirect jump is useful to study the targets
of the jump.
