    perf annotate: Create hotkey 'c' to show min/max cycles · 3e71fc03
    Jin Yao authored
    In the 'perf annotate' view, a new hotkey 'c' is created for showing the
    min/max cycles.
    
    For example, when press 'c', the annotate view is:
    
      Percent│ IPC     Cycle(min/max)
             │
             │
             │                             Disassembly of section .text:
             │
             │                             000000000003aab0 <random@@GLIBC_2.2.5>:
        8.22 │3.92                           sub    $0x18,%rsp
             │3.92                           mov    $0x1,%esi
             │3.92                           xor    %eax,%eax
             │3.92                           cmpl   $0x0,argp_program_version_hook@@G
             │3.92             1(2/1)      ↓ je     20
             │                               lock   cmpxchg %esi,__abort_msg@@GLIBC_P
             │                             ↓ jne    29
             │                             ↓ jmp    43
             │1.10                     20:   cmpxchg %esi,__abort_msg@@GLIBC_PRIVATE+
        8.93 │1.10             1(5/1)      ↓ je     43
    
    When press 'c' again, the annotate view is switched back:
    
      Percent│ IPC Cycle
             │
             │
             │                Disassembly of section .text:
             │
             │                000000000003aab0 <random@@GLIBC_2.2.5>:
        8.22 │3.92              sub    $0x18,%rsp
             │3.92              mov    $0x1,%esi
             │3.92              xor    %eax,%eax
             │3.92              cmpl   $0x0,argp_program_version_hook@@GLIBC_2.2.5+0x
             │3.92     1      ↓ je     20
             │                  lock   cmpxchg %esi,__abort_msg@@GLIBC_PRIVATE+0x8a0
             │                ↓ jne    29
             │                ↓ jmp    43
             │1.10        20:   cmpxchg %esi,__abort_msg@@GLIBC_PRIVATE+0x8a0
        8.93 │1.10     1      ↓ je     43
