-# 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

-# 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.

-### name size align
-#FIELD _plaintext, 8, 8 # pointer to plaintext
-#FIELD _ciphertext, 8, 8 # pointer to ciphertext
-#FIELD _IV, 16, 8 # IV
-#FIELD _keys, 8, 8 # pointer to keys
-#FIELD _len, 4, 4 # length in bytes
-#FIELD _status, 4, 4 # status enumeration
-#FIELD _user_data, 8, 8 # pointer to user data
-#UNION _union, size1, align1, \
-# size2, align2, \
-# size3, align3, \
-# ...
-#END_FIELDS
-#%assign _JOB_AES_size _FIELD_OFFSET
-#%assign _JOB_AES_align _STRUCT_ALIGN
-
-#########################################################################
-
-# 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.

-# 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.
