Christian Eggers 502794d432 Fix several mix up between octets and bytes in ELF program headers
When converting between addresses in ELF headers [octets] and bfd
LMA/VMA [bytes], the number of octets per byte needs to be
incorporated.

In ld, the SIZEOF_HEADERS linker script statement must be resolved to
bytes instead of octets.

include/
	* elf/internal.h (struct elf_internal_phdr): Add unit (octets)
	to several member field comments.
	(Elf_Internal_Shdr): likewise.
bfd/
	* elf.c (_bfd_elf_make_section_from_shdr): Introduce new temp
	opb.  Divide Elf_Internal_Shdr::sh_addr by opb when setting
	section LMA/VMA.
	(_bfd_elf_make_section_from_phdr): Similarly.
	(elf_fake_sections): Fix calculation of
	Elf_Internal_shdr::sh_addr from section VMA.
	(_bfd_elf_map_sections_to_segments): Fix mixup between octets
	and bytes.
	(assign_file_positions_for_load_sections): Fix calculations of
	Elf_Internal_shdr::p_vaddr and p_paddr from section LMA/VMA.  Fix
	comparison between program header address and section LMA.
	(assign_file_positions_for_non_load_sections): Likewise.
	(rewrite_elf_program_header): Likewise.  Introduce new temp opb.
	(IS_CONTAINED_BY_VMA): Add parameter opb.
	(IS_CONTAINED_BY_LMA,IS_SECTION_IN_INPUT_SEGMENT,
	INCLUDE_SECTION_IN_SEGMENT): Likewise.
	(copy_elf_program_header): Update call to ELF_SECTION_IN_SEGMENT.
	Fix calculations of p_addr_valid and p_vaddr_offset.
	* elflink.c (elf_link_add_object_symbols): Multiply section VMA
	with octets per byte when comparing against p_vaddr.
ld/
	* ldexp.c (fold_name): Return SIZEOF_HEADERS in bytes.

		   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.
