/* This file performs the following test: start, stop and timer functionality for 
   PAPI_L1_TCM derived event

   - They are counted in the default counting domain and default
     granularity, depending on the platform. Usually this is
     the user domain (PAPI_DOM_USER) and thread context (PAPI_GRN_THR).
   - Get us.
   - Start counters
   - Do flops
   - Stop and read counters
   - Get us.
