Hi,
While running perf on some function-heavy code I noticed the ETM return stack isn't enabled (TRCCONFIGR bit 9). I know that it can easily be enabled with retstack=1, but have we considered making this the default as we move to simplification of perf options? It could lead to more efficient profiles and shouldn't be any more difficult to decode than ETM normally is.
