When we are performing unaligned stack accesses in the 32-64B window we have to do a read-modify-write cycle. E.g. for reading 8 bytes from address 17: 0: tmp = stack[16] 1: gprLo = tmp >> 8 2: tmp = stack[20] 3: gprLo |= tmp << 24 4: tmp = stack[20] 5: gprHi = tmp >> 8 6: tmp = stack[24] 7: gprHi |= tmp << 24 The load on line 4 is unnecessary, because tmp already contains data from stack[20]. For write we can optimize both loads and writebacks away.
