Subject: [PATCH v1 0/4] perf annotate: Create a new '--tui-dump' option

There is a requirement to let perf annotate support displaying the IPC/Cycle.
In previous patch, this is supported in TUI mode. While it's not convenient
for users since they have to take screen shots and copy/paste data.

This patch series introduces a new option '--tui-dump' in perf annotate to
dump the TUI output to stdio.

User can easily use the command line like:
'perf annotate --tui-dump > /tmp/log.txt' 
 
For example:
    $ perf annotate compute_flag --tui-dump

    Percent  IPC Cycle

                            Disassembly of section .text:

                            0000000000400640 <compute_flag>:
                            compute_flag():
                            volatile int count;
                            static unsigned int s_randseed;

                            __attribute__((noinline))
                            int compute_flag()
                            {
     23.00  1.16              sub    $0x8,%rsp
                                    int i;

                                    i = rand() % 2;
     23.06  1.16     1        callq  rand@plt

                                    return i;
     27.01  3.38              mov    %eax,%edx
                            }
            3.38              add    $0x8,%rsp
                            {
                                    int i;

                                    i = rand() % 2;

                                    return i;
            3.38              shr    $0x1f,%edx
            3.38              add    %edx,%eax
            3.38              and    $0x1,%eax
            3.38              sub    %edx,%eax
                            }
     26.93  3.38     2        retq

The '--stdio' option is still kept now. Maybe in future, we can only
maintain the TUI routines and drop the lagacy stdio code. But right
now we'd better keep it until the '--tui-dump' option is good enough.

Jin Yao (4):
  perf browser: Add a new 'dump' flag
  perf browser: bypass ui_init if in tui dump mode
  perf annotate: Process the new switch flag tui_dump
  perf annotate: Enable the '--tui-dump' mode
