This patch provides helper routines to support new columns for block
info output.
The new columns are:
Sampled Cycles%
Sampled Cycles
Avg Cycles%
Avg Cycles
[Program Block Range]
Shared Object
v5:
---
1. Move more block related functions from builtin-report.c to
block-info.c
2. Set ms (map+sym) in block hist_entry. Because this info
is needed for reporting the block range (i.e. source line)
Committer notes:
Remove unused set_fmt() function, some build were not completing with:
util/block-info.c:396:20: error: unused function 'set_fmt' [-Werror,-Wunused-function]
static inline void set_fmt(struct block_fmt *block_fmt,
^
1 error generated.
