Commit: MSP430 sim: Fix detection of illegal memory accesses

[Nick Clifton]

Hi Guys,

  I am applying the attached patch to fix a couple of problems with the
  MSP430 simulator.  The first was that the code to detect illegal
  memory accesses was not taking into account the address size of the
  instruction, nor did the simulator's memory map match that used by the
  linker scripts.  The second problem was that the simulator insisted on
  loading an executable file, but some GDB tests run without an
  executable.

  Tested with no regressions with an msp430-elf toolchain.

Cheers
  Nick

	* msp430-sim.c (sim_open): Allocate memory regions matching those
	declared in the libgloss/msp430 linker scripts.
	Allow sim_load_file to fail.
	(get_op): Test the correct address bit when checking for out of
	range addresses.
	Include the address in the error message when an illegal access to
	the hardware multiplier is detected.
	(put_op): Test the correct address bit when checking for out of
	range addresses.
