"The instruction can take an optional align attribute. The alignment must be a power of two greater or equal to the size of the <value> type. If unspecified, the alignment is assumed to be equal to the size of the ‘<value>’ type. Note that this default alignment assumption is different from the alignment used for the load/store instructions when align isn’t specified." |
