* Ok. Following are the relocation information macros. If your
|
|
* system should not be able to use the default set (below), you must
|
|
* define the following:
|
|
|
|
* relocation_info: This must be typedef'd (or #define'd) to the type
|
|
* of structure that is stored in the relocation info section of your
|
|
* a.out files. Often this is defined in the a.out.h for your system.
|
|
*
|
|
* RELOC_ADDRESS (rval): Offset into the current section of the
|
|
* <whatever> to be relocated. *Must be an lvalue*.
|
|
*
|
|
* RELOC_EXTERN_P (rval): Is this relocation entry based on an
|
|
* external symbol (1), or was it fully resolved upon entering the
|
|
* loader (0) in which case some combination of the value in memory
|
|
* (if RELOC_MEMORY_ADD_P) and the extra (if RELOC_ADD_EXTRA) contains
|
|
* what the value of the relocation actually was. *Must be an lvalue*.
|
|
*
|
|
* RELOC_TYPE (rval): If this entry was fully resolved upon
|
|
* entering the loader, what type should it be relocated as?
|
|
*
|
|
* RELOC_SYMBOL (rval): If this entry was not fully resolved upon
|
|
* entering the loader, what is the index of it's symbol in the symbol
|
|
* table? *Must be a lvalue*.
|
|
*
|
|
* RELOC_MEMORY_ADD_P (rval): This should return true if the final
|
|
* relocation value output here should be added to memory, or if the
|
|
* section of memory described should simply be set to the relocation
|
|
* value.
|
|
*
|
|
* RELOC_ADD_EXTRA (rval): (Optional) This macro, if defined, gives
|
|
* an extra value to be added to the relocation value based on the
|
|
* individual relocation entry. *Must be an lvalue if defined*.
|
|
*
|
|
* RELOC_PCREL_P (rval): True if the relocation value described is
|
|
* pc relative.
|
|
*
|
|
* RELOC_VALUE_RIGHTSHIFT (rval): Number of bits right to shift the
|
|
* final relocation value before putting it where it belongs.
|
|
*
|
|
* RELOC_TARGET_SIZE (rval): log to the base 2 of the number of
|
|
* bytes of size this relocation entry describes; 1 byte == 0; 2 bytes
|
|
* == 1; 4 bytes == 2, and etc. This is somewhat redundant (we could
|
|
* do everything in terms of the bit operators below), but having this
|
|
* macro could end up producing better code on machines without fancy
|
|
* bit twiddling. Also, it's easier to understand/code big/little
|
|
* endian distinctions with this macro.
|
|
*
|
|
* RELOC_TARGET_BITPOS (rval): The starting bit position within the
|
|
* object described in RELOC_TARGET_SIZE in which the relocation value
|
|
* will go.
|
|
*
|
|
* RELOC_TARGET_BITSIZE (rval): How many bits are to be replaced
|
|
* with the bits of the relocation value. It may be assumed by the
|
|
* code that the relocation value will fit into this many bits. This
|
|
* may be larger than RELOC_TARGET_SIZE if such be useful.
|
|
*
|
|
*
|
|
* Things I haven't implemented
|
|
* ----------------------------
|
|
*
|
|
* Values for RELOC_TARGET_SIZE other than 0, 1, or 2.
|
|
*
|

/* If a this type of symbol is encountered, its name is a warning

|
|
|
|
This feature may be used to allow backwards compatibility with
|
|
certain functions (eg. gets) but to discourage programmers from
|
|
their use.
|
|
|
|
So if, for example, you wanted to have ld print a warning whenever
|
|
the function "gets" was used in their C program, you would add the
|
|
following to the assembler file in which gets is defined:
|
|
|
|
.stabs "Obsolete function \"gets\" referenced",30,0,0,0
|
|
.stabs "_gets",1,0,0,0
|
|
|
|
These .stabs do not necessarily have to be in the same file as the
|
|
gets function, they simply must exist somewhere in the compilation. */

/* The following type indicates the definition of a symbol as being

an indirect reference to another symbol. The other symbol

appears as an undefined reference, immediately following this symbol.
|

|
|
Indirection is asymmetrical. The other symbol's value will be used
|
|
to satisfy requests for the indirect symbol, but not vice versa.
|
|
If the other symbol does not have a definition, libraries will
|
|
be searched to find a definition.
|
|
|
|
So, for example, the following two lines placed in an assembler
|
|
input file would result in an object file which would direct gnu ld
|
|
to resolve all references to symbol "foo" as references to symbol
|
|
"bar".

/* The following symbols refer to set elements. These are expected
|
|
only in input to the loader; they should not appear in loader
|
|
output (unless relocatable output is requested). To be recognized
|
|
by the loader, the input symbols must have their N_EXT bit set.
|
|
All the N_SET[ATDB] symbols with the same name form one set. The
|
|
loader collects all of these elements at load time and outputs a
|
|
vector for each name.
|
|
Space (an array of 32 bit words) is allocated for the set in the
|
|
data section, and the n_value field of each set element value is
|
|
stored into one word of the array.
|
|
The first word of the array is the length of the set (number of
|
|
elements). The last word of the vector is set to zero for possible
|
|
use by incremental loaders. The array is ordered by the linkage
|
|
order; the first symbols which the linker encounters will be first
|
|
in the array.
|
|
|
|
In C syntax this looks like:
|
|
|
|
struct set_vector {
|
|
unsigned int length;
|
|
unsigned int vector[length];
|
|
unsigned int always_zero;
|
|
};
|
|
|
|
Before being placed into the array, each element is relocated
|
|
according to its type. This allows the loader to create an array
|
|
of pointers to objects automatically. N_SETA type symbols will not
|
|
be relocated.
|
|
|
|
The address of the set is made into an N_SETV symbol
|
|
whose name is the same as the name of the set.
|
|
This symbol acts like a N_DATA global symbol
|
|
in that it can satisfy undefined external references.
|
|
|
|
For the purposes of determining whether or not to load in a library
|
|
file, set element definitions are not considered "real
|
|
definitions"; they will not cause the loading of a library
|
|
member.
|
|
|
|
If relocatable output is requested, none of this processing is
|
|
done. The symbols are simply relocated and passed through to the
|
|
output file.
|
|
|
|
So, for example, the following three lines of assembler code
|
|
(whether in one file or scattered between several different ones)
|
|
will produce a three element vector (total length is five words;
|
|
see above), referenced by the symbol "_xyzzy", which will have the
|
|
addresses of the routines _init1, _init2, and _init3.
|
|
|
|
*NOTE*: If symbolic addresses are used in the n_value field of the
|
|
defining .stabs, those symbols must be defined in the same file as
|
|
that containing the .stabs.
|
|
|
|
.stabs "_xyzzy",23,0,0,_init1
|
|
.stabs "_xyzzy",23,0,0,_init2
|
|
.stabs "_xyzzy",23,0,0,_init3
|
|
|
|
Note that (23 == (N_SETT | N_EXT)). */
