Pnut bug with REP and AUGS

ozpropdev

Hi Chip
I've encountered a bug in Pnut that icorrectly encodes the REP instruction block length when the immediate value is > 9 bits. (AUGS applied)
Here's the sample code source

		orgh	$12000
		org

		rep	@rblk1,#511
		add	myreg1,myreg2 wz
	if_z	sub	myreg1,myreg2 wc
	if_nc	xor	myreg1,myreg2 wz,wc
rblk1
		rep	@rblk2,##512		'<-- Repeat block length +1 error
		add	myreg1,myreg2 wz
	if_z	sub	myreg1,myreg2 wc
	if_nc	xor	myreg1,myreg2 wz,wc
rblk2
		mov	myreg3,##512
		rep	@rblk3,myreg3
		add	myreg1,myreg2 wz
	if_z	sub	myreg1,myreg2 wc
	if_nc	xor	myreg1,myreg2 wz,wc
rblk3

Here's is my disassembly of Pnut's output

Thanks, Brian! I'll fix that tomorrow.
