[PATCH 17/52] perf c2c report: Add stores related dimension keys

Arnaldo Carvalho de Melo
2016-10-20T15:18:04Z

Add 5 stores related dimension key wrappers.

First 3 are to be displayed in the main cachelines overall output:

stores, stores_l1hit, stores_l1miss

The latter 2 are to be displayed within single cacheline output:

cl_stores_l1hit, cl_stores_l1miss

They all display bare numbers of stores for cacheline or its related
offsets.
