# XDEF ****************************************************************	#
#	_060LSP__idivu64_(): Emulate 64-bit unsigned div instruction.	#
#	_060LSP__idivs64_(): Emulate 64-bit signed div instruction.	#
#									#
#	This is the library version which is accessed as a subroutine	#
#	and therefore does not work exactly like the 680X0 div{s,u}.l	#
#	64-bit divide instruction.					#
