Hi,
The linux perf tool has some basic support for annotating
AArch32 branch instructions when displaying assembly. This
patchset refactors the annotation support to have a cleaner
separation between architectures, and then adds support for
annotating AArch64 instructions.
Comments very welcome, thanks.
Chris.

How about annotating a perf.data file collected on ARM on a x86_64 machine? I think we should have this keyed by the arch name and have all the tables available, using the one we get from the perf.data header. Look at the "[PATCH v4 2/6] perf tools: Promote proper messages for cross-platform unwind " patch, it has the bits you need to get the arch from the perf.data file header (session->machines->machine->env->arch) I applied the first patch. - Arnaldo > Signed-off-by: Chris Ryder <chris.ryder@arm.com> > Acked-by: Pawel Moll <pawel.moll@arm.com> > Cc: Peter Zijlstra
