+
+; Alternate "struc-like" syntax:
+; STRUCT job_aes2
+; RES_Q .plaintext, 1
+; RES_Q .ciphertext, 1
+; RES_DQ .IV, 1
+; RES_B .nested, _JOB_AES_SIZE, _JOB_AES_ALIGN
+; RES_U .union, size1, align1, \
+; size2, align2, \
+; ...
+; ENDSTRUCT
+; ; Following only needed if nesting
+; %assign job_aes2_size _FIELD_OFFSET
+; %assign job_aes2_align _STRUCT_ALIGN
+;
+; RES_* macros take a name, a count and an optional alignment.
+; The count in in terms of the base size of the macro, and the
+; default alignment is the base size.
+; The macros are:
+; Macro Base size
+; RES_B 1
+; RES_W 2
+; RES_D 4
+; RES_Q 8
+; RES_DQ 16
+; RES_Y 32
+; RES_Z 64
+;
+; RES_U defines a union. It's arguments are a name and two or more
+; pairs of "size, alignment"
+;
+; The two assigns are only needed if this structure is being nested
+; within another. Even if the assigns are not done, one can still use
+; STRUCT_NAME_size as the size of the structure.
+;
+; Note that for nesting, you still need to assign to STRUCT_NAME_size.
+;
+; The differences between this and using "struc" directly are that each
+; type is implicitly aligned to its natural length (although this can be
+; over-ridden with an explicit third parameter), and that the structure
+; is padded at the end to its overall alignment.
