Hi,

	Immediate AND operation with exr register fails with H8 simulator.
	
	When I debug the following program compiled with the command line 
"h8300-elf-gcc test.c -ms -g " under gdb simulator it doesn't show the proper result.

/***************************** Start of test.s *****************************/
int main ()
{
	asm ("mov #0x07, r0");
	asm ("ldc r0l, exr");
	asm ("andc #0x89, exr");
	return 1;
}
/***************************** End of test.c *****************************/	

Please find below patch which fixes the same.
