; -- All loads/stores from parameters aligned by one must be done one
;    byte at a time.
; -- Notes:
;   -- There are two fields of interest in the packed part of the struct, one
;      with a proper offset and one without. The former should be loaded or
;      stored as a whole, and the latter by bytes.
;   -- Only loading and storing the said fields are checked in the following
;      series of tests so that they are more concise.
