Arnaldo Carvalho de Melo b793a40185 perf annotate browser: Hide non jump target addresses in offset mode
This:

    0.00 :         ffffffff8116bd00:       lock btsl $0x0,(%r12)
  100.00 :         ffffffff8116bd07:       sbb    %eax,%eax
    0.00 :         ffffffff8116bd09:       test   %eax,%eax
    0.00 :         ffffffff8116bd0b:       jne    ffffffff8116bf5f <__mem_cgroup_commit_charge+0x28f>
    0.00 :         ffffffff8116bd11:       mov    (%r12),%rax
    0.00 :         ffffffff8116bd15:       test   $0x2,%al
    0.00 :         ffffffff8116bd17:       jne    ffffffff8116bf6e <__mem_cgroup_commit_charge+0x29e>
    0.00 :         ffffffff8116bd1d:       test   %r9b,%r9b
    0.00 :         ffffffff8116bd20:       jne    ffffffff8116be30 <__mem_cgroup_commit_charge+0x160>
    0.00 :         ffffffff8116bd26:       xor    %eax,%eax
    0.00 :         ffffffff8116bd28:       mov    %r13,0x8(%r12)
    0.00 :         ffffffff8116bd2d:       lock orb $0x2,(%r12)
    0.00 :         ffffffff8116bd33:       test   %r9b,%r9b

Becomes:

    0.00 :         30:       lock btsl $0x0,(%r12)
  100.00 :                   sbb    %eax,%eax
    0.00 :                   test   %eax,%eax
    0.00 :                   jne    28f
    0.00 :                   mov    (%r12),%rax
    0.00 :                   test   $0x2,%al
    0.00 :                   jne    29e
    0.00 :                   test   %r9b,%r9b
    0.00 :                   jne    160
    0.00 :         56:       xor    %eax,%eax
    0.00 :         58:       mov    %r13,0x8(%r12)
    0.00 :                   lock orb $0x2,(%r12)
    0.00 :                   test   %r9b,%r9b
    0.00 :                   je     123

I.e. We trow away all those useless addresses and keep just jump labels.
