Unrelated to this, do you know how SFrame support (ie. in userspace)
is going? This was/is the great hope for fast, low overhead stack
traces without frame pointers, but it's all gone a bit quiet. The
last thing I heard was a talk by Steve Rostedt a few years ago.
I plan to write up a Fedora 43 proposal for that. For realistic
experiments, we need at least one distribution that does not have frame
pointers (otherwise the SFrame data is rather different and not
representative at all of a frame-pointer-less environment), so I plan
to
propose to disable them again in ELN.
Would it make sense to leverage the CentOS ISA SIG instead to run these
experiments? While CentOS Stream 11 is still ways out, it seems
premature to disable frame pointers in ELN now, as my understanding is
that while SFrame is being developed, it is not a viable replacement
yet, and it might be a while till it'll get there.
