[PATCH] perf report: Fix no branch type statistics report issue
From: Jin Yao
Date: Fri Mar 13 2020 - 09:46:40 EST
Previously we could get the report of branch type statistics.
For example,
perf record -j any,save_type ...
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.
Fixes: 40c39e304641 ("perf report: Fix a no annotate browser displayed issue")
