I looked recently in this code and wondered, how the lse_cas works for
8, and 16 bit values. CAS It does a load with 32 or 64 bits and compares
these bits. The upper 16 or 24 bits may not be equal and the CAS will
In short: lse_cas does not work on 8 and 16 bit values.
Please correct me if I am wrong.
