Subject: Make BasicAliasAnalysis a normal AliasAnalysis implementation which
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=c1be92f3bb9158eade30d97db6997e2fe78150ab;p=oota-llvm.git

Make BasicAliasAnalysis a normal AliasAnalysis implementation which
does normal initialization and normal chaining. Change the default
AliasAnalysis implementation to NoAlias.

Update StandardCompileOpts.h and friends to explicitly request
BasicAliasAnalysis.

Update tests to explicitly request -basicaa.
