v5: --- Mainly the v5 patch series are updated according to comments from Jiri Olsa <jolsa@redhat.com>.
The kernel part doesn't have functional change. It just solve the merge issue.
In userspace, the functions of branch type counting and branch type name resolving are moved to the new files: util/branch.c, util/branch.h.
And refactor the branch info printing code for better maintenance.
Not changed (or just fix merge issue): perf/core: Define the common branch type classification perf/x86/intel: Record branch type perf record: Create a new option save_type in --branch-filter
New patches: perf report: Refactor the branch info printing code perf util: Create branch.c/.h for common branch functions
Changed: perf report: Show branch type statistics for stdio mode perf report: Show branch type in callchain entry
v4: --- 1. Describe the major changes in patch description. Thanks for Peter Zijlstra's reminding.
2. Initialize branch type to 0 in intel_pmu_lbr_read_32 and intel_pmu_lbr_read_64. Remove the invalid else code in intel_pmu_lbr_filter.
v3: --- 1. Move the JCC forward/backward and cross page computing from kernel to userspace.
2. Use lookup table to replace original switch/case processing.
Changed: perf/core: Define the common branch type classification perf/x86/intel: Record branch type perf report: Show branch type statistics for stdio mode perf report: Show branch type in callchain entry
Not changed: perf record: Create a new option save_type in --branch-filter
v2: --- 1. Use 4 bits in perf_branch_entry to record branch type.
2. Pull out some common branch types from FAR_BRANCH. Now the branch types defined in perf_event.h:
