Haswell supports reporting the data address for a range of PEBS events, including: UOPS_RETIRED.ALL MEM_UOPS_RETIRED.STLB_MISS_LOADS MEM_UOPS_RETIRED.STLB_MISS_STORES MEM_UOPS_RETIRED.LOCK_LOADS MEM_UOPS_RETIRED.SPLIT_LOADS MEM_UOPS_RETIRED.SPLIT_STORES MEM_UOPS_RETIRED.ALL_LOADS MEM_UOPS_RETIRED.ALL_STORES MEM_LOAD_UOPS_RETIRED.L1_HIT MEM_LOAD_UOPS_RETIRED.L2_HIT MEM_LOAD_UOPS_RETIRED.L3_HIT MEM_LOAD_UOPS_RETIRED.L1_MISS MEM_LOAD_UOPS_RETIRED.L2_MISS MEM_LOAD_UOPS_RETIRED.L3_MISS MEM_LOAD_UOPS_RETIRED.HIT_LFB MEM_LOAD_UOPS_L3_HIT_RETIRED.XSNP_MISS MEM_LOAD_UOPS_L3_HIT_RETIRED.XSNP_HIT MEM_LOAD_UOPS_L3_HIT_RETIRED.XSNP_HITM MEM_LOAD_UOPS_L3_HIT_RETIRED.XSNP_NONE MEM_LOAD_UOPS_L3_MISS_RETIRED.LOCAL_DRAM This facility was already enabled earlier with the original Haswell perf changes. However these addresses were always reports as stores by perf, which is wrong, as they could be loads too. The hardware does not distinguish loads and stores for these instructions, so there's no (cheap) way for the profiler to find out. Change the type to PERF_MEM_OP_NA instead.
