# This test is targeting stores.
# Access pattern: A, C, E, G, A, C, I, K, E, G
# 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 with FIFO replacement policy, you will observe:
# m, m, m, m, h, h, m, m, h, h
# where 'm' means miss, and 'h' means hit.

# Explanation of this result:
# A, C, E, G are misses, now the cache stores
# ([A*, C, E, G],[ , , ,]), A marked * as the next entry to be evicted.
# A hits.
# Now the cache stores ([A*, C, E, G],[ , , ,]).
# C hits.
# Now the cache stores ([A*, C, E, G],[ , , ,]).
# I misses, searches for a victim and selects A.
# Now the cache stores ([I, C*, E, G],[ , , ,]).
# K misses, searches for a victim and selects C.
# Now the cache stores ([I, K, E*, G],[ , , ,]).
# E hits.
# Now the cache stores ([I, K, E*, G],[ , , ,]).
# G hits
# Now the cache stores ([I, K, E*, G],[ , , ,]).
