Devang Patel	dca8d3b183	Do not ignore iv uses outside the loop. This one slipped through cracks very well. llvm-svn: 56284	2008-09-17 17:53:47 +00:00
Devang Patel	51cbf928ab	If loop induction variable's start value is less then its exit value then do not split the loop. llvm-svn: 53265	2008-07-09 00:12:01 +00:00
Devang Patel	ee7bf41c06	Do not erase induction variable increment if it is used outside the loop. llvm-svn: 51280	2008-05-19 22:23:55 +00:00
