Hi,
I'm trying to use 'perf record' to find the hotspot inside a function.
The results I'm seeing are confusing. 'annotate' claims that a simple
'add' instruction is the main CPU time consumer"
0.00 : 408246: mov 0x8(%rbp),%rsi
0.31 :
40824a: mov 0x10(%rbp),%rcx
0.00 : 40824e:
lea 0x4(%rcx),%rdi
0.81 : 408252: mov
0x6(%rbx),%rbx
0.00 : 408256: mov
0x18(%rbx,%rax,8),%r8
---> 27.58 : 40825b: add $0x20,%rbp
0.00 : 40825f: jmpq 408338 <Main_zdwpolyzugo_info>
0.00 : 408264:
mov $0x7b9609,%ebx
0.00 : 408269: add
$0x20,%rbp
0.00 : 40826d: jmpq *0x0(%rbp)
5.41 : 408270: mov 0xd(%rbx),%rax
How shall I interpret this? Is it really the following jump that is to blame?
