H A D | parse-branch-options.c | diff 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.

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.
