Jan W. Jagersma 4d095f5b5e coff-go32-exe: support variable-length stubs
The stub size in GO32 executables has historically been fixed at 2048
bytes, due to hardcoded limitations in bfd.  Recent patches to djgpp by
Stas Sergeev (CC'd) have pushed the stub right up to this limit, so if
any further expansion is desired, this must first be patched in bfd.

This series includes three patches:  The first changes the meaning of
the bfd->origin field slightly, so that target code can use this to
specify an offset into the file where the actual bfd is located.
The second patch then uses this to enable support for variable-sized
stubs in the coff-go32-exe format.
The final patch is only a cleanup, it normalizes function and variable
names in coff-stgo32.c so that they all begin with the same prefix.

bfd	* bfdio.c (bfd_bread, bfd_tell, bfd_seek, bfd_mmap): Always add
	bfd->origin to file offset.
	* bfdwin.c (bfd_get_file_window): Likewise.
	* bfd.c: Clarify the use of the bfd->origin field.
	* bfd-in2.h: Regenerate.
	* coff-i386.c: Don't include go32exe.h. Allow overriding
	coff_write_object_contents via COFF_WRITE_CONTENTS.
	* coff-stgo32.c (go32exe_cleanup, go32exe_mkobject)
	(go32exe_write_object_contents): New functions.
	(go32exe_temp_stub, go32exe_temp_stub_size): New static globals.
	(COFF_WRITE_CONTENTS, GO32EXE_DEFAULT_STUB_SIZE): Define.
	(create_go32_stub): Remove check for 2k size limit.  Read stub
	from go32exe_temp_stub if present.
	(go32_stubbed_coff_bfd_copy_private_bfd_data): Allocate and
	copy variable-length stub.
	(go32_check_format): Read stub to go32exe_temp_stub, set
	origin, return go32exe_cleanup.
	(adjust_filehdr_in_post, adjust_filehdr_out_pre)
	(adjust_filehdr_out_post, adjust_scnhdr_in_post)
	(adjust_scnhdr_out_pre, adjust_scnhdr_out_post)
	(adjust_aux_in_post, adjust_aux_out_pre, adjust_aux_out_post):
	Remove functions and their associated #defines.
	* coffcode.h (coff_mkobject_hook): Remove stub copying code.
	* libcoff-in.h: (struct coff_tdata): New field stub_size.
	Rename field go32stub to stub.
	* libcoff.h: Regenerate.
	* coff-stgo32.c (go32_check_format): Rename to...
	(go32exe_check_format): ...this.
	(go32_stubbed_coff_bfd_copy_private_bfd_data): Rename to...
	(go32exe_copy_private_bfd_data): ...this.
	(stub_bytes): Rename to...
	(go32exe_default_stub): ...this.
	(create_go32_stub): Rename to...
	(go32exe_create_stub): ...this.
	* coff-stgo32.c (go32exe_copy_private_bfd_data): Avoid realloc
	when possible.

include	* coff/go32exe.h: Remove file.
	* coff/internal.h (struct internal_filehdr): Remove field
	go32stub.  Remove flag F_GO32STUB.

README

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
