A slew of temporary FIXMEs indicate the intention of the no-self-wrap flag without changing behavior in this revision. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127590 91177308-0d34-0410-b5e6-96231b3b80d8
*	Disable the asserts that check that normalization is perfectly	Dan Gohman	2010-09-03	1	-2/+7
\| \| \| \| \| \| \| \| \| \|	invertible. ScalarEvolution's folding routines don't always succeed in canonicalizing equal expressions to a single canonical form, and this can cause these asserts to fail, even though there's no actual correctness problem. This fixes PR8066. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113021 91177308-0d34-0410-b5e6-96231b3b80d8

*	Generalize IVUsers to track arbitrary expressions rather than expressions	Dan Gohman	2010-04-07	1	-0/+150
	explicitly split into stride-and-offset pairs. Also, add the ability to track multiple post-increment loops on the same expression. This refines the concept of "normalizing" SCEV expressions used for to post-increment uses, and introduces a dedicated utility routine for normalizing and denormalizing expressions. This fixes the expansion of expressions which are post-increment users of more than one loop at a time. More broadly, this takes LSR another step closer to being able to reason about more than one loop at a time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100699 91177308-0d34-0410-b5e6-96231b3b80d8
