//Try to thrash ! used godbolt!

// Cache ways 1,2,3 do not have SelFlush = 0
|
|
// To make SelFlush = 0 we must evict lines from ways 1,2,3
|
|
// Will load 4 words with same tags, filling 4 ways of cache
|
|
// edit and store these words so that dirty bit is set ( is this necessary?)
|
|
// Will then load 4 more words, evicting the previous 4 words
|
|
// will make SelFlush = 0 for all 4 ways.
|
|
|
|
// Load code to initialize stack, handle interrupts, terminate
