Allow to run standard perf script with useful default options too. - Normal perf script - perf script with assembler (needs xed installed) - perf script with source code output (needs debuginfo) - perf script with custom arguments Then we automatically select the right options to display the information in the perf.data file. For example with -b display branch contexts. It's not easily possible to check for xed's existence in advance. perf script usually gives sensible error messages when it's not available.
