Hi Arnaldo,

Thanks for your reply.

I profiled a few applications and here are the results.

What do you think of these results ?
Should there be a selectable mode specified in .perfconfig ?
I will investigate in reducing the size of the file as well. As, we only need the link register in theory.

Also for the compilation on different platforms
What do you think of this fix ?

I've tested this patchset on a few different applications and have seen it significantly improve
quality of frame pointer stacks on aarch64. For example with GDB 10 and default build options,
'bfd_calc_gnu_debuglink_crc32' is a leaf function, and its caller 'gdb_bfd_crc' is ommitted,
but with the patchset it is included. I've also confirmed that this is correct from looking at
the source code.

There is a question about whether the overhead of recording all the registers is acceptable, for
filesize and time. We could make it a manual step, at the cost of not showing better frame pointer
stacks by default.

Can someone quantify this, i.e. how much space per perf.data for a
typical scenario? But anyway, I'm applying it as is now, we can change
it if needed, its not like files with the extra registers won't be
valid if/when we decide not to collect it by default in the future.

If we decide to make this selectable, we should have it as a .perfconfig
knob as well, so that one can set it and change the default, etc.

This is unconditionally asking for asm/perf_regs.h and it is not available
everywhere, so I think this has to be abstracted away, maybe using a weak
function that arm provides a replacement for?

Is this for doing cross-platform analysis? I.e. record a perf.data file
on arm64 and then do a perf-report on it on a x86_64 machine? Yeah, that
is expected to work, but then:
