Andrew Burgess bac13f5a4c AVR/ld: Use .avr.prop data during linker relaxation.
Make use of the data held within the .avr.prop section during linker
relaxation in order to maintain the properties of the .org and .align
directives.

In relation to the .align directives, if enough bytes are deleted before
a .align directive then the alignment can be moved while still
maintaining the alignment requirement.

bfd/ChangeLog:

	* elf32-avr.c (struct elf_avr_section_data): New structure.
	(struct avr_relax_info): New structure.
	(elf_avr_new_section_hook): New function.
	(struct elf_avr_section_data): Add relax_info.
	(get_avr_relax_info): New function.
	(init_avr_relax_info): New function.
	(elf32_avr_relax_delete_bytes): Find next property record before
	deleting bytes.  When deleting don't move bytes beyond the next
	property record.
	(avr_elf32_assign_records_to_section): New function.
	(avr_property_record_compare): New function.
	(avr_load_all_property_sections): New function.
	(elf32_avr_relax_section): Load property data.  After relaxing the
	section, move any .align directives that have enough deleted bytes
	before them.
	(bfd_elf32_new_section_hook): Define.

		   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.
