swapping functions into coffswap.h for ECOFF use. Moved

relocation functions, only used by h8300 and z8k, into reloc16.c.

FUNCTION
|
||||
The bfd_get_size function
|
||||
|
||||
SYNOPSIS
|
||||
long bfd_get_size(bfd *);
|
||||
|
||||
DESCRIPTION
|
||||
Return file size (as read from file system) for the file
|
||||
associated with a bfd.
|
||||
|
||||
Note that the initial motivation for, and use of, this routine is not
|
||||
so we can get the exact size of the object the bfd applies to, since
|
||||
that might not be generally possible (archive members for example?).
|
||||
Although it would be ideal if someone could eventually modify
|
||||
it so that such results were guaranteed.
|
||||
|
||||
Instead, we want to ask questions like "is this NNN byte sized
|
||||
object I'm about to try read from file offset YYY reasonable?"
|
||||
As as example of where we might want to do this, some object formats
|
||||
use string tables for which the first sizeof(long) bytes of the table
|
||||
contain the size of the table itself, including the size bytes.
|
||||
If an application tries to read what it thinks is one of these
|
||||
string tables, without some way to validate the size, and for
|
||||
some reason the size is wrong (byte swapping error, wrong location
|
||||
for the string table, etc), the only clue is likely to be a read
|
||||
error when it tries to read the table, or a "virtual memory
|
||||
exhausted" error when it tries to allocated 15 bazillon bytes
|
||||
of space for the 15 bazillon byte table it is about to read.
|
||||
This function at least allows us to answer the quesion, "is the
|
||||
size reasonable?".
