Hi Hal, Thanks. How about a symbol with two different immediate offsets - the Value* would be the same, right? I don't see how AliasAnalysis::Location would handle this... And BasicAliasAnalysis does if (V1 == V2) return MustAlias; , so I'm not sure how this would be done .. ? /Jonas > -----Original Message----- > From: Hal Finkel [mailto:hfinkel at anl.gov] > Sent:

Hi! My llvm version is 3.0 release. I have a module generated by clang. When I optimize it, I first add an inlining pass (llvm::createFunctionInliningPass), then these passes: - own FunctionPass - llvm::createPromoteMemoryToRegisterPass - llvm::createInstructionCombiningPass - llvm::createDeadInstEliminationPass - llvm::createDeadStoreEliminationPass - new llvm::DominatorTree() - new
