*	Avoid creating canonical induction variables for non-native types.	Andrew Trick	2011-03-18	1	-1/+1
\| \| \| \| \| \| \| \| \|	For example, on 32-bit architecture, don't promote all uses of the IV to 64-bits just because one use is a 64-bit cast. Alternate implementation of the patch by Arnaud de Grandmaison. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127884 91177308-0d34-0410-b5e6-96231b3b80d8

This change also flattens IVUsers, eliminating the stride-oriented groupings, which makes it easier to work with. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95975 91177308-0d34-0410-b5e6-96231b3b80d8

*	Generalize SCEVExpander::visitAddRecExpr's GEP persuit, and avoid	Dan Gohman	2009-05-24	1	-0/+78
	sending SCEVUnknowns to expandAddToGEP. This avoids the need for expandAddToGEP to bend the rules and peek into SCEVUnknown expressions. Factor out the code for testing whether a SCEV can be factored by a constant for use in a GEP index. This allows it to handle SCEVAddRecExprs, by recursing. As a result, SCEVExpander can now put more things in GEP indices, so it emits fewer explicit mul instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72366 91177308-0d34-0410-b5e6-96231b3b80d8
