Hi All, I'm relatively new to LLVM (but not optimizing compilers), and have been reading docs and browsing code. I noticed in the 2.4 release notes that a sparse propagation framework had been added based on the SCCP algorithm. I might have a need for exactly this kind of framework in order to prototype an analysis I have in mind. I also noticed, however, that this doesn't appear to be

I've written an optimization loop, with the following form: PassManager lpm; lpm.add(createLoopDeletionPass()); lpm.add(createSCCPPass()); lpm.add(createAggressiveDCEPass()); lpm.add(createGlobalOptimizerPass()); lpm.add(createGlobalDCEPass()); lpm.add(createDeadStoreEliminationPass()); lpm.add(createLoopDeletionPass()); lpm.add(createInstructionCombiningPass()); lpm.add(createCFGSimplificationPa...

...ction, so none of the related passes are needed). My first attempt at collecting useful optimizations looks like this: passManager->add(new TargetData(*executionEngine->getTargetData())); passManager->add(createScalarReplAggregatesPass()); // Convert to SSA form passManager->add(createSCCPPass()); // Propagate constants passManager->add(createInstructionCombiningPass()); // Peephole optimization passManager->add(createDeadStoreEliminationPass()); // Dead store elimination passManager->add(createAggressiveDCEPass()); // Aggressive dead code elimi...

Andy and I briefly discussed this the other day, we have not yet got chance to list a detailed pass order for the pre- and post- IPO scalar optimizations. This is wish-list in our mind: pre-IPO: based on the ordering he propose, get rid of the inlining (or just inline tiny func), get rid of all loop xforms... post-IPO: get rid of inlining, or maybe we still need it, only
