Symbol offset is one of the fields that can be requested in perf-script.
Currently you do not get that data when requested. e.g.,
perf script -f comm,tid,pid,time,cpu,sym,symoff,ip
...
gcc 6201/6201 [006] 762250.617897:
ffffffff81090d95 update_curr
ffffffff810911b8 dequeue_entity
ffffffff81091825 dequeue_task_fair
ffffffff81087163 dequeue_task
ffffffff81087c03 deactivate_task
...
With this patch you get the offset:
...
gcc 6201/6201 [006] 762250.617897:
ffffffff81090d95 update_curr+0x1c5
ffffffff810911b8 dequeue_entity+0x28

ffffffff81087163 dequeue_task+0x93
ffffffff81087c03 deactivate_task+0x23
