Owen Anderson	d62d37225a	Use the new addEscapingValue callback to update GlobalsModRef when GVN adds PHIs of GEPs. For the moment, ... have GlobalsModRef handle this conservatively by simply removing the value from its maps. llvm-svn: 122787	2011-01-03 23:51:43 +00:00
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
