When using the Linux "perf" tool to do system profiling, symbol names of running Java methods cannot be decoded. Considering that perf can read a simple text file format describing the mapping between address ranges and symbol names for a particular process, it will be very convenient if Hotspot could write this file directly using a diagnostic command.
