The goal of this change is to achieve consistent output for symbol address.
Before this, the raw ip is printed for non-callchain and dso offset for
callchain. Mostly what we expect is the raw ip.
This patch does two changes:
- Always print raw ip for resolved symbols.
- Add a new 'dsoff' field if we really need the dso offset, and the
offset is appended to dso name.
v2:
o split into two patches.
o do not print offset for unresolved symbols.
Changbin Du (2):
perf script: print raw ip instead of binary offset for callchain
perf: script: add new output field 'dsoff' to print dso offset
