parentperf annotate: Allow printing objdump line addr in different color (diff)
perf ui annotate browser: Allow toggling addr offset view
The lines in objdump have this format: ffffffff8126543f: jne ffffffff81265494 <__list_del_entry+0x84> <SNIP> ffffffff81265494: mov %rdi,%rcx Since we now have objdump_line allowing tools to print the offset independently from the rest of the line, allow toggling a view where just offsets from the start of the function are shown: 2f: jne ffffffff81265494 <__list_del_entry+0x84> <SNIP> 84: mov %rdi,%rcx The offset view will be the default as soon as operations that deal with offsets in a function are handled accodringly, i.e. in offset view the above will become: 2f: jne __list_del_entry+0x84 <SNIP> 84: mov %rdi,%rcx And then a follow up patch will allow navigating thru jumps, just like we handle callq instructions.
