Subject[PATCH 05/10] perf, tool: Split out PE_VALUE_SYM parsing token to SW and HW tokens
Date
Spliting PE_VALUE_SYM token to PE_VALUE_SYM_HW and PE_VALUE_SYM_SW
tokens to separate hardware and software symbols.

This will be usefull in upcomming patch where we want to be able
to parse out only hardware events.
