When we have a colored line in perf annotate, ie a middle/high overhead one, it's sometimes useful to get the matching line and filename from the source file, especially this path prepares to another subsequent one which will print a sorted summary of midle/high overhead lines in the beginning of the output. Filename:Lines have the same color than the concerned ip lines. It can be slow because it relies on addr2line. We could also use objdump with -l but that implies we would have to bufferize objdump output and parse it to filter the relevant lines since we want to print a sorted summary in the beginning.
