45  * This standalone program is used to generate the contents
46  * of the struct_layout_XXX.c files that contain per-archtecture
47  * structure layout information.
48  *
49  * Although not part of elfdump, it is built by the makefile
50  * along with it.
51  * To use it:
52  *
53  *	1) Run it, capturing the output in a file.
54  *	2) If this is a replacement for an existing file,
55  *		diff the new and old copies to ensure only
56  *		the changes you expected are present.
57  *	3) Put the new file in the common directory under the name
58  *		struct_layout_XXX.c, where XXX is the name of
59  *		the architecture (i386, amd64, sparc, sparcv9, etc).
60  *	2) Add any necessary header and copyright comments.
61  *	3) If this is a new architecture:
62  *		- Add an extern statement for struct_layout_XXX()
63  *			to struct_layout.h
64  *		- Add a case for it to the function sl_struct_layout()
65  *			in struct_layout.c.
