[PATCH RFC 0/3] perf script: Add callindent option

From: Adrian Hunter
Date: Thu Jun 16 2016 - 08:38:48 EST


Andi Kleen sent a couple of patches to add a callindent option to
perf script. If Andi is agreeable, I would like to propose an
alternative implementation.

While there are some differences in the resulting output, the main
differences are:

1. Tell the decoder to feed branches to the thread stack, which has the
advantage that it happens before branch filtering and so can be used
with different itrace options (e.g. it still works when only showing
calls, even though the thread stack needs to see calls and returns). Also
it does not conflict with using the thread stack to get callchains.

2. Print "call" or "ret" instead of using a different event

perf auxtrace: Add option to feed branches to the thread stack
