perf annotate: Introduce ->free() method in ins_ops

2012-05-12T16:26:20+00:00

So that we don't special case disasm_line__free, allowing each
instruction class to provide an specialized destructor, like is needed
for 'lock'.

perf annotate: Augment lock instruction output

2012-05-12T16:15:34+00:00

It just chops off the 'lock' and uses the ins__find, etc machinery to
call instruction specific parsers/beautifiers.

perf annotate: Resolve symbols using objdump comment

2012-05-11T20:19:20+00:00

This:

     mov    0x95bbb6(%rip),%ecx        # ffffffff81ae8d04 

Becomes:

     mov    d_hash_shift,%ecx

Ditto for many more instructions that take two operands.

perf annotate browser: Do raw printing in 'o'ffset in a single place

2012-05-07T21:54:16+00:00

Instead of doing the same in all ins scnprintf methods.

perf annotate: Mark jump instructions with no offset

2012-04-25T17:16:03+00:00

I.e. jumps that go to code outside the current function, that is denoted
in objdump -dS as:

   399f877a9f: jne    399f87bcf4 <_L_lock_5154>

I.e. without the + after the name of the current function, like in:

   399f877aa5: jmp    399f877ab2 <_int_free+0x412>

The browser will use that info to avoid drawing connectors to the start
of the function, since ops.target.addr was zero.

perf annotate: Disambiguage offsets and addresses in operands

2012-04-25T11:00:23+00:00

We were using ins_ops->target for callq addresses and jump offsets,
disambiguate by having ins_ops->target.addr and ins_ops->target.offset.

For jumps we'll need both to fixup lines that don't have an offset on
the <> part.

perf annotate browser: Suppress the callq address

2012-04-20T18:26:47+00:00

    0.00 |       callq  ffffffff8112f190 <__mod_zone_page_state>

Becomes:

    0.00 |       callq  __mod_zone_page_state

But if you press 'o' it gets verbose, i.e. as in objdump -dS:

    0.00 | ffffffff8116bdda:  callq  ffffffff8112f190 <__mod_zone_page_state>

perf annotate: Group operands members

2012-04-20T17:38:46+00:00

So that the ins_ops can handle them in a single place, instead of adding
more and more functions or ins_ops parameters.

perf annotate: Introduce scnprintf ins_ops method

2012-04-19T13:16:27+00:00

And implement the jump one, where if the operands string is not passed,
a compact form that uses just the target address is used.

Right now this is toggled via the 'o' option in the annotate browser,
switching from:

    0.00 :         ffffffff811661e8:       je     ffffffff81166204 
    0.00 :         ffffffff811661ea:       cmp    $0xb,%esi
    0.00 :         ffffffff811661ed:       je     ffffffff811661f8 

To:

    0.00 :         28:       je     44
    0.00 :         2a:       cmp    $0xb,%esi
    0.00 :         2d:       je     38

2012-04-18T19:07:38+00:00

No need to do it everytime the user presses enter/-> on a call
instruction.
