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.
