/*
* 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.
*/
/*
* These macros create indexes for accessing the bytes of
* words and halfwords for ELFCLASS32 data representations
* (currently ELFDATA2LSB and ELFDATA2MSB). In all cases,
*
* w = (((((X_3 << 8) + X_2) << 8) + X_1) << 8) + X_0
* h = (X_1 << 8) + X_0
*
* These assume the file representations for Addr, Off,
* Sword, and Word use 4 bytes, but the memory def's for
* the types may differ.
*
* Naming convention:
* ..._L ELFDATA2LSB
* ..._M ELFDATA2MSB
*
* enuma_*(n) define enum names for addr n
* enumb_*(n) define enum names for byte n
* enumh_*(n) define enum names for half n
* enumo_*(n) define enum names for off n
* enumw_*(n) define enum names for word n
* enuml_*(n) define enum names for Lword n
* tofa(d,s,n) xlate addr n from mem s to file d
* tofb(d,s,n) xlate byte n from mem s to file d
* tofh(d,s,n) xlate half n from mem s to file d
* tofo(d,s,n) xlate off n from mem s to file d
* tofw(d,s,n) xlate word n from mem s to file d
* tofl(d,s,n) xlate Lword n from mem s to file d
* toma(s,n) xlate addr n from file s to expression value
* tomb(s,n) xlate byte n from file s to expression value
* tomh(s,n) xlate half n from file s to expression value
* tomo(s,n) xlate off n from file s to expression value
* tomw(s,n) xlate word n from file s to expression value
* toml(s,n) xlate Lword n from file s to expression value
*
* tof*() macros must move a multi-byte value into a temporary
* because ``in place'' conversions are allowed. If a temp is not
* used for multi-byte objects, storing an initial destination byte
* may clobber a source byte not yet examined.
*
* tom*() macros compute an expression value from the source
* without touching the destination; so they're safe.
