|
||||
|
||||
Merge Per Bothner's changes to modularize BFD a.out a bit.
|
||||
|
||||
* libbfd.h, libbfd.c (bfd_generic_get_section_contents): Add.
|
||||
* ieee.c: Cast enums to int before comparing them, for brain-
|
||||
dead compilers.
|
||||
* coff-code.h: Remove coff_get_section_contents, and use the
|
||||
generic one instead.
|
||||
|
||||
* aout.c: Derive new module from sunos.c, containing generic
|
||||
support code for all kinds of a.out files.
|
||||
|
||||
* sunos.c: Remove all code that goes in aout.c. Split out
|
||||
machine dependent followup in sunos4_object_p into
|
||||
sunos4_callback. Use JUMP_TABLE(aout) for the transver vector,
|
||||
and redefine only the names we CHANGE, not all the names. Drop
|
||||
the little-endian vector, and rename the vector as sunos4 rather
|
||||
than generic.
|
||||
|
||||
* b.out.c: Use aout.c routines for most of the work. Slight
|
||||
changes for the new regime. Remove close_and_cleanup and
|
||||
get_section_contents in favor of generics. New transfer vector
|
||||
regime.
|
||||
|
||||
* newsos.c: New support for Sony NEWS, another a.out format.
|
||||
|
||||
* ecoff.c: Remove close_and_cleanup. New tvec regime.
|
||||
* icoff.c, m88k-bcs.c: Add write_contents to tvec.
|
||||
* ieee.c, oasys.c: Remove close_and_cleanup, add write_contents
|
||||
to tvec.
|
||||
* opncls.c (bfd_close): Call format-dependent write_contents
|
||||
routine, if writing, before calling target-dependent
|
||||
close_and_cleanup routine (which is now always generic, I think).
|
||||
* srec.c: Use bfd_alloc instead of malloc. Remove
|
||||
close_and_cleanup and move code from it to
|
||||
srec_write_object_contents. Add write_contents to tvec.
|
||||
* targets.c: Remove a.out little vector, replace a.out big
|
||||
vector with SunOS vector. FIXME: Need Vax support again now.
|
||||
|
||||
* libbfd.h: Add write_contents format-dependent-vector to the
|
||||
bfd_target vector. Supply a generic close_and_cleanup routine.
|
||||
* liba.out.h: Handle the new aout.c split. Add prototypes for
|
||||
all routines defined in aout.c. Rename "sunos" things to "aout"
|
||||
things. Add a few fields where needed for various formats.
|
||||
* Makefile.in: Add aout.c and newsos.c.
|
||||
|
||||
* archive.c, ieee.c, oasys.c: Lint.

* ecoff.c: Clean up types and such. Remove routines that are
|
||||
not used. Fix up reading and swapping of shorts from files.
|
||||
|
||||
Notes on bfd-0.5.2-patch1a, from Per Bothner:
|
||||
|
||||
* a.out.vax.c: Remove two bogus "static" from prototypes.
|
||||
|
||||
* ecoff.c: Got rid of lots of non-working junk (that had
|
||||
been copied directly from coff-code.h).
|
||||
Updated to be consistent with updates to icoff.c and coff-code.h.
|
||||
|
||||
* libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
|
||||
if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
|
||||
|
||||
* sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
|
||||
but until the target_vector is automatically generated,
|
||||
it's as good as any. Note that the text offset is the only
|
||||
difference between NewsOS and SunOs (including magic numbers).
|
||||
(Most of the sunos_* routines should to renamed bsd_*
|
||||
and move to a bsd.c file. Then (and when the target_vector
|
||||
is automatically generated) it might make sense to create
|
||||
a separate Sony target.)
|
||||
|
||||
* sysdep.h: Don't declare fread and fwrite. Causes trouble
|
||||
on some systems, and doesn't help on others.
|
||||
Similarly, only define X_OK if not already defined.
|
||||
|
||||
* trad-core.c: Don't include sys/stat.h - at least
|
||||
on NewsOS 3, it has already been included.
