perf annotate browser: Bandaid offsets/jump label objdump ambiguity
We need to cope with things like: $ objdump -d --no-show-raw -S -C /lib/modules/3.4.0-rc2+/build/vmlinux <SNIP> ffffffff8125ec60 <copy_user_generic_unrolled>: * Output: * eax uncopied bytes or 0 if successful. */ ENTRY(copy_user_generic_unrolled) CFI_STARTPROC cmpl $8,%edx ffffffff8125ec60: cmp $0x8,%edx jb 20f /* less then 8 bytes, go to byte copy loop */ ffffffff8125ec63: jb ffffffff8125ecf5 <copy_user_generic_unrolled+0x95> ALIGN_DESTINATION <SNIP> ffffffff8125ec8d: je ffffffff8125ecd9 <copy_user_generic_unrolled+0x79> 1: movq (%rsi),%r8 ffffffff8125ec8f: mov (%rsi),%r8 2: movq 1*8(%rsi),%r9 ffffffff8125ec92: mov 0x8(%rsi),%r9 3: movq 2*8(%rsi),%r10 ffffffff8125ec96: mov 0x10(%rsi),%r10 4: movq 3*8(%rsi),%r11 <SNIP> Probably expect that the length of the addr field be the same... Lazy move for now, back to supporting suppressing the address on callq lines...
