# This test is targeting stores
# Access pattern: A, A, A, C, C, E, E, G, I, K, M, O, A
# Each letter represents a 64-byte address range.

# The [] indicate two different sets, and each set has four ways.
# [set0way0, set0way1, set0way2, set0way3],
# [set1way0, set1way1, set1way2, set1way3],
# If you have a 512B cache with 4-way associativity,
# and each cache line is 64B. This test can be used to test the correctness
# of RRIP replacement policy. More specifically, with RRIP replacement
# policy, you will observe: m, h, h, m, h, m, h, m, m, m, m, m, h
# where 'm' means miss, and 'h' means hit.

# Explanation of this result:
# After three A access, two C accesses, 2 E accesses and one G access,
# the cache stores ([A0, C1, E1, G2],[ , , ,]).
# The number following each letter is the RRPV for that address range.
# I searches a victim and selects G. Now the cache stores ([A1, C2, E2, I2],[ , , ,]).
# K searches a victim and selects C. Now the cache stores ([A2, K2, E3, I3],[ , , ,]).
# M searches a victim and selects E. Now the cache stores ([A2, K2, M2, I3],[ , , ,]).
# O searches a victim and selects I. NOW the cache stores ([A2, K2, M2, O2],[ , , ,]).
# A hits.
