/*
 * fmsize:  Array used to determine what size the the structures
 *	    are (for memory image & file image).
 *
 * x32:  Translation routines - to file & to memory.
 *
 * What must be done when adding a new type for conversion:
 *
 * The first question is whether you need a new ELF_T_* type
 * to be created.  If you've introduced a new structure - then
 * it will need to be described - this is done by:
 *
 * o adding a new type ELF_T_* to usr/src/head/libelf.h
 * o Create a new macro to define the bytes contained in the structure. Take a
 *   look at the 'Syminfo_1' macro defined below.  The declarations describe
 *   the structure based off of the field size of each element of the structure.
 * o Add a entry to the fmsize table for the new ELF_T_* type.
 * o Create a <newtype>_11_tof macro.  Take a look at 'syminfo_11_tof'.
 * o Create a <newtype>_11_tom macro.  Take a look at 'syminfo_11_tom'.
 * o The <newtype>_11_tof & <newtype>_11_tom results in conversion routines
 *   <newtype>_2L11_tof, <newtype>_2L11_tom, <newtype>_2M11_tof,
 *   <newtype>_2M11_tom being created in xlate.c.  These routines
 *   need to be added to the 'x32[]' array.
 * o Add entries to getdata.c::align32[] and getdata.c::align64[].  These
 *   tables define what the alignment requirements for a data type are.
 *
 * In order to tie a section header type (SHT_*) to a data
 * structure you need to update elf32_mtype() so that it can
 * make the association.  If you are introducing a new section built
 * on a basic datatype (SHT_INIT_ARRAY) then this is all the updating
 * that needs to be done.
 *
 *
 * ELF translation routines
 *	These routines make a subtle implicit assumption.
 *	The file representations of all structures are "packed,"
 *	meaning no implicit padding bytes occur.  This might not
 *	be the case for the memory representations.  Consequently,
 *	the memory representations ALWAYS contain at least as many
 *	bytes as the file representations.  Otherwise, the memory
 *	structures would lose information, meaning they're not
 *	implemented properly.
 *
 *	The words above apply to structures with the same members.
 *	If a future version changes the number of members, the
 *	relative structure sizes for different version must be
 *	tested with the compiler.

 *	tof*() macros must move a multi-byte value into a temporary

 *	tom*() macros compute an expression value from the source
 *	without touching the destination; so they're safe.
