	* compile.c (h8300_normal_mode): New.
	(SP): Handle normal mode.
	(bitfrom): Use normal mode flag to return suitable value.

	flag.

2003-07-18  Michael Snyder  <[e-mail]>

	* compile.c (decode): Enhancements for mova.
	Initialize cst, reg, and rdisp inside the loop, for each
	new instruction.  Defer correction of the disp2 values until

	rather than the size of the instruction.
	(sim_resume): For mova, adjust the size of the second operand
	according to the type of the first operand (INDEXB vs. INDEXW).
	In cases where there is only one operand, the other two must
	both be composed on the fly.
