syms.c (asymbol): Added new field "app_data", for data particular to the
application. Some of the linker flags ought to get moved to this field someday. archures.c (bfd_default_scan): Recognize a few more numbers: 80486, 80960, and 960. bfd-in.h, bfd.c, targets.c, coffcode.h, coff-mips.c, other targets: Moved COFF swap table to backend data. hosts/i386linux.h: Include unistd.h. aoutx.h, libaout.h, stab-syms.c: stab names are now in constant storage. trad-core.c: Fixed some `PARAMS' uses that were missing parentheses. aoutx.h, archive.c, archures.c, coffcode.h, ctor.c, reloc.c, syms.c: Doc fixes.

* hosts/i386linux.h: Include unistd.h.
|

* aoutx.h (print_symbol): aout_stab_name returns a constant
|
||||
string.
|

* libaout.h (aout_stab_name): Fix prototype.
|
||||
* stab-syms.c (aout_stab_names): Array is now const.
|

(aout_stab_name): Return value is now pointer to const.

80486, 80960, and 960.
|
||||
|
||||
* bfd-in.h (COFF_SWAP_TABLE): New is just address of
|
||||
bfd_coff_std_swap_table, cast to PTR.
|
||||
* bfd.c (bfd_coff_swap_*): Deleted macros.
|
||||
* targets.c (struct bfd_target): Deleted COFF-specific swapping
|
||||
routine pointers.
|
||||
* coffcode.h (type bfd_coff_backend_data): New structure type,
|
||||
contains pointers to the COFF-specific swapping routines.
|
||||
(bfd_coff_std_swap_table): New data structure, to be used when
|
||||
NO_COFF_SYMBOLS and NO_COFF_LINENOS are not defined.
|
||||
(bfd_coff_swap_*): New macros.
|
||||
* coff-mips.c (mips_coff_swap_table): New data structure.
|
||||
(ecoff_big_vec): Use it.
|
||||
* All COFF targets: Moved COFF_SWAP_TABLE to target-specific data.
|
||||
* All other targets: Deleted coff-specific vector entries.
|
||||
|
||||
* trad-core.c: Fixed some `PARAMS' uses that were missing

parentheses.

DESCRIPTION
|
||||
This function is called with an a symbol describing the
|
||||
function to be called, an string which descibes the xtor type,
|
||||
eg something like "CTOR" or "DTOR" would be fine. And the bfd
|
||||
e.g., something like "CTOR" or "DTOR" would be fine. And the bfd
|
||||
which owns the function. Its duty is to create a section
|
||||
called "CTOR" or "DTOR" or whatever if the bfd doesn't already
|
||||
have one, and grow a relocation table for the entry points as
