File perf-report-fix-no-branch-type-statistics-report-issue.patch of Package perf.16341
From: Jin Yao <yao.jin@linux.intel.com> Date: Fri, 13 Mar 2020 21:46:07 +0800 Subject: perf report: Fix no branch type statistics report issue Git-commit: c3b10649a80e9da2892c1fd3038c53abd57588f6 Patch-mainline: v5.7-rc1 References: git-fixes X-Info: adjust context, no 32dcd021d0040 Previously we could get the report of branch type statistics. For example: # perf record -j any,save_type ... # t perf report --stdio # # Branch Statistics: # COND_FWD: 40.6% COND_BWD: 4.1% CROSS_4K: 24.7% CROSS_2M: 12.3% COND: 44.7% UNCOND: 0.0% IND: 6.1% CALL: 24.5% RET: 24.7% But now for the recent perf, it can't report the branch type statistics. It's a regression issue caused by commit 40c39e304641 ("perf report: Fix a no annotate browser displayed issue"), which only counts the branch type statistics for browser mode. This patch moves the branch_type_count() outside of ui__has_annotation() checking, then branch type statistics can work for stdio mode.
