* gas/config/tc-arm.c (encode_thumb32_addr_mode): Set inst.reloc.pc_rel
	if is_pc.
	(T16_32_TAB): Delete unused entry for BLX.
	(do_t_ldst): Don't offset inst.reloc.exp.X_add_number for PC-relative
	addressing.
	(md_pcrel_from): Report the adjusted PC for
	BFD_RELOC_ARM_THUMB_OFFSET and BFD_RELOC_ARM_T32_OFFSET_IMM.
	(md_apply_fix3): Correct bitmasks for BFD_RELOC_ARM_T32_OFFSET_IMM.
	Do not round up value for PC-relative BFD_RELOC_ARM_THUMB_OFFSET.

	* gas/testsuite/gas/arm/thumb.s: Test PC-relative ldr more thoroughly.
	* gas/testsuite/gas/arm/thumb.d: Update to match.

	* gas/testsuite/gas/arm/thumb32.s: Properly align labels that
	will be targeted by blx instructions.
	* gas/testsuite/gas/arm/thumb32.d: Update to match.  Correct
	expected dissassembly of PC-relative ldr.

	* gas/testsuite/gas/arm/macro1.s: Add leading label and
	trailing padding for a.out compatibility.
	* gas/testsuite/gas/arm/macro1.d: Update to match.
	* gas/testsuite/gas/arm/tcompat2.s: Add trailing padding for a.out
	compatibility.

	* opcodes/arm-dis.c (print_insn_thumb32): Reorganize %a and %A
	handling.  Call info->print_address_func when %a/%A are applied
	to a PC-relative instruction.

		   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.
