Thanks for the feedback, the `--show-mmap-events` here is different from the linux `perf script`, here is to show the mmap events paring results, only for debugging use I think.

And in this test, see the directive: `; CHECK-IGNORE-NOT: Mmap: Binary /home/a.out loaded at 0x400000` which means `--show-mmap-events ` won't work with `--ignore-mmap-events`.

I can add a warning here if it's confusing.
