Hi, list

what does mean annotate.show_nr_jumps ?


If I configure 'annotate.show_nr_jumps' with a boolean 'false'
The output is as below..

         │1382:   movb   $0x1,-0x270(%rbp)
         │          ↑ jmpq   1223
         │            xchg   %ax,%ax
3.51 │1390:   mov    -0x210(%rbp),%rax
         │            movslq %r15d,%rsi
         │            mov    0x68(%rax),%rax
         │            testb  $0x10,0x1(%rax,%rsi,2)
7.89 │         ↑ je     be6
2.63 │13a9:   mov    %r9,%rbx

========================================================

And If I set 'true' to it, the output is as below

         │    1 1382:   movb   $0x1,-0x270(%rbp)
         │                 ↑ jmpq   1223
         │                   xchg   %ax,%ax
3.51 │    1 1390:   mov    -0x210(%rbp),%rax
         │                   movslq %r15d,%rsi
         │                   mov    0x68(%rax),%rax
         │                   testb  $0x10,0x1(%rax,%rsi,2)
7.89 │                 ↑ je     be6
2.63 │    1 13a9:   mov    %r9,%rbx

What does mean the number '1' in front of address such as  " 1 13a9: " ?


Thanks,
Taeung
