Dan Gohman	9130bad71f	Extend the AliasAnalysis::pointsToConstantMemory interface to allow it ... to optionally look for constant or local (alloca) memory. Teach BasicAliasAnalysis::pointsToConstantMemory to look through Select and Phi nodes, and to support looking for local memory. Remove FunctionAttrs' PointsToLocalOrConstantMemory function, now that AliasAnalysis knows all the tricks that it knew. llvm-svn: 118412	2010-11-08 16:45:26 +00:00
Dan Gohman	da85ed8541	Move NoAA out of BasicAliasAnalysis.cpp into its own file, now that ... it doesn't have a special relationship with BasicAliasAnalysis anymore. llvm-svn: 116876	2010-10-19 23:09:08 +00:00
