Adding support to add field(s) to default sort order via using the '+'
prefix, like for report:
$ perf report
Samples: 2K of event 'cycles', Event count (approx.): 882172583
Overhead Command Shared Object Symbol
7.39% swapper [kernel.kallsyms] [k] intel_idle
1.97% firefox libpthread-2.17.so [.] pthread_mutex_lock
1.39% firefox [snd_hda_intel] [k] azx_get_position
1.11% firefox libpthread-2.17.so [.] pthread_mutex_unlock
$ perf report -s +cpu
Samples: 2K of event 'cycles', Event count (approx.): 882172583
Overhead Command Shared Object Symbol CPU
2.89% swapper [kernel.kallsyms] [k] intel_idle 000
2.61% swapper [kernel.kallsyms] [k] intel_idle 002
1.20% swapper [kernel.kallsyms] [k] intel_idle 001
0.82% firefox libpthread-2.17.so [.] pthread_mutex_lock 002
Works in general for commands using --sort option.
v2 with changes suggested:
- Use dynamic memory instead static buffer
- Fix error message typo
