|
|
This command reads the input file and displays an annotated version of the
|
|
|
|
|
code. If the object file has debug symbols then the source code will be
|
|
|
|
|
displayed alongside assembly code.
|
|
|
|
|
|
|
|
|
|
If there is no debug info in the object, then annotated assembly is displayed.

perf annotate: Add basic support to event group view
Add --group option to enable event grouping. When enabled, all the
group members information will be shown with the leader so skip
non-leader events.
It only supports --stdio output currently. Later patches will extend
additional features.
