46 * fmsize:  Array used to determine what size the the structures
47 *	    are (for memory image & file image).
48 *
49 * x32:  Translation routines - to file & to memory.
50 *
51 * What must be done when adding a new type for conversion:
52 *
53 * The first question is whether you need a new ELF_T_* type
54 * to be created.  If you've introduced a new structure - then
55 * it will need to be described - this is done by:
56 *
57 * o adding a new type ELF_T_* to usr/src/head/libelf.h
58 * o Create a new macro to define the bytes contained in the structure. Take a
59 *   look at the 'Syminfo_1' macro defined below.  The declarations describe
60 *   the structure based off of the field size of each element of the structure.
61 * o Add a entry to the fmsize table for the new ELF_T_* type.
62 * o Create a <newtype>_11_tof macro.  Take a look at 'syminfo_11_tof'.
63 * o Create a <newtype>_11_tom macro.  Take a look at 'syminfo_11_tom'.
64 * o The <newtype>_11_tof & <newtype>_11_tom results in conversion routines
65 *   <newtype>_2L11_tof, <newtype>_2L11_tom, <newtype>_2M11_tof,
66 *   <newtype>_2M11_tom being created in xlate.c.  These routines
67 *   need to be added to the 'x32[]' array.
68 * o Add entries to getdata.c::align32[] and getdata.c::align64[].  These
69 *   tables define what the alignment requirements for a data type are.
70 *
71 * In order to tie a section header type (SHT_*) to a data
72 * structure you need to update elf32_mtype() so that it can
73 * make the association.  If you are introducing a new section built
74 * on a basic datatype (SHT_INIT_ARRAY) then this is all the updating
75 * that needs to be done.
76 *
77 *
78 * ELF translation routines
79 *	These routines make a subtle implicit assumption.
80 *	The file representations of all structures are "packed,"
81 *	meaning no implicit padding bytes occur.  This might not
82 *	be the case for the memory representations.  Consequently,
83 *	the memory representations ALWAYS contain at least as many
84 *	bytes as the file representations.  Otherwise, the memory
85 *	structures would lose information, meaning they're not
86 *	implemented properly.
87 *
88 *	The words above apply to structures with the same members.
89 *	If a future version changes the number of members, the
90 *	relative structure sizes for different version must be
91 *	tested with the compiler.

129 *	tomw(s,n)	xlate word n from file s to expression value
130 *	toml(s,n)	xlate Lword n from file s to expression value
131 *
132 *	tof*() macros must move a multi-byte value into a temporary
133 *	because ``in place'' conversions are allowed.  If a temp is not
134 *	used for multi-byte objects, storing an initial destination byte
135 *	may clobber a source byte not yet examined.
136 *
137 *	tom*() macros compute an expression value from the source
138 *	without touching the destination; so they're safe.
