Nick Clifton 5ab6d79e70 More AArch64 simulator improvements.
* cpustate.c (aarch64_get_FP_half): New function.  Read a vector
	register as a half precision floating point number.
	(aarch64_set_FP_half): New function.  Similar, but for setting
	a half precision register.
	(aarch64_get_thread_id): New function.  Returns the value of the
	CPU's TPIDR register.
	(aarch64_get_FPCR): New function.  Returns the value of the CPU's
	floating point control register.
	(aarch64_set_FPCR): New function.  Set the value of the CPU's FPCR
	register.
	* cpustate.h: Add prototypes for new functions.
	* sim-main.h (struct _sim_cpu): Add FPCR and tpidr fields.
	* memory.c: Use unaligned core access functions for all memory
	reads and writes.
	* simulator.c (HALT_NYI): Generate an error message if tracing
	will not tell the user why the simulator is halting.
	(HALT_UNREACHABLE): Delete.  Delete (unneeded) uses of the macro.
	(INSTR): New time-saver macro.
	(fldrb_abs): New function.  Loads an 8-bit value using a scaled
	offset.
	(fldrh_abs): New function.  Likewise for 16-bit values.
	(do_vec_SSHL): Allow for negative shift values.
	(do_vec_USHL): Likewise.
	(do_vec_SHL): Correct computation of shift amount.
	(do_vec_SSHR_USHR): Correct decision of signed vs unsigned
	shifts and computation of shift value.

	functions.
	(system_get): Add support for TPIDR, CTR, FPCR, FPSR and CPSR
	registers.
	(system_set): New function.
	(do_MSR_immediate): New function.  Stub for now.
	(do_MSR_reg): New function.  Likewise. Partially implements MSR
	instruction.
	(do_SYS): New function.  Stub for now,
	(dexSystem): Call new functions.

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.
