perf annotate: Fix missing number of samples for source_line_samplesperf-core-for-mingo-4.12-20170404
The option 'show-total-period' works fine without a option '-l'. But if
running 'perf annotate --stdio -l --show-total-period', you can see a
problem showing only zero '0' for number of samples.
Before:
$ perf annotate --stdio -l --show-total-period
...
0 : 400816: push %rbp
0 : 400817: mov %rsp,%rbp
0 : 40081a: mov %edi,-0x24(%rbp)
0 : 40081d: mov %rsi,-0x30(%rbp)
0 : 400821: mov -0x24(%rbp),%eax
0 : 400824: mov -0x30(%rbp),%rdx
0 : 400828: mov (%rdx),%esi
0 : 40082a: mov $0x0,%edx
...
The reason is it was missed to set number of samples of
source_line_samples, so set it ordinarily.
After:
$ perf annotate --stdio -l --show-total-period
...
3 : 400816: push %rbp
4 : 400817: mov %rsp,%rbp
0 : 40081a: mov %edi,-0x24(%rbp)
0 : 40081d: mov %rsi,-0x30(%rbp)
1 : 400821: mov -0x24(%rbp),%eax
2 : 400824: mov -0x30(%rbp),%rdx
0 : 400828: mov (%rdx),%esi
1 : 40082a: mov $0x0,%edx
...
