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
