*	Eliminate uses of %prcontext.	Daniel Dunbar	2009-09-05	1	-1/+3
\| \| \| \| \| \| \|	- I'd appreciate it if someone else eyeballs my changes to make sure I captured the intent of the test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81083 91177308-0d34-0410-b5e6-96231b3b80d8
*	Teach SCEVExpander's visitAddRecExpr to reuse an existing canonical	Dan Gohman	2009-06-13	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	induction variable when the addrec to be expanded does not require a wider type. This eliminates the need for IndVarSimplify to micro-manage SCEV expansions, because SCEVExpander now automatically expands them in the form that IndVarSimplify considers to be canonical. (LSR still micro-manages its SCEV expansions, because it's optimizing for the target, rather than for other optimizations.) Also, this uses the new getAnyExtendExpr, which has more clever expression simplification logic than the IndVarSimplify code it replaces, and this cleans up some ugly expansions in code such as the included masked-iv.ll testcase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73294 91177308-0d34-0410-b5e6-96231b3b80d8
