...ple to do your measurements yourself (and I'd love to hear the results!) : cd llvm svn switch http://llvm.org/svn/llvm-project/llvm/branches/ggreif/use-diet . make rebuild llvm-gcc, etc. retest. And now here is my educated speculation: There are 2 things that became slower 1) Use::getUser() 2) Use::get/set due to tagging. The former is seldom called: $ find lib -name "*.cpp" | xargs grep "getUser(" | wc -l 41 We could audit those to make sure that no unnecessary calls are done. But the getUse() algorithm is not sooo inefficient, anyway. The second is co...

I searched the doxygen documentation and could not find a solution to my task: In a ModulePass running at EP_OptimizerLast, if I have a function F like in: bool Foo:runOnModule(Module &M) { LLVMContext &C = M.getContext(); for (auto &F : M) { // magic here if I want to know from which function (callee) each function is called - how can I do this?

...int arg2 = arg1 + c; int arg3 = arg2 + c; // 2 muls and 3 adds/subs. 1 add/sub less than with the reversed order I have a proof-of-concept patch ( http://reviews.llvm.org/differential/diff/25402/) that has CollectFixupsAndInitialFormulae to sort initial formulae in a dominance order (i.e. if A.getUser() dominates B.getUser(), then we put A before B). It breaks some tests that are too sensitive to order changes; besides that, I don't see significant issues. Jingyue -------------- next part -------------- An HTML attachment was scrubbed...

Hi. This is part of my code: ... if (auto* op = dyn_cast<BinaryOperator>(&I)) { Value* lhs = op->getOperand(0); Value* rhs = op->getOperand(1); Value* mul = builder.CreateMul(lhs, rhs); for (auto& U : op->uses()) { User* user = U.getUser(); user->setOperand(U.getOperandNo(), mul); } I.eraseFromParent(); } ...

Hi everyone, Instruction and Value classes have "Uses" and "User". What is the difference between them? I think that "Uses" gives all the instructions/values that a particular Value depends on and "User" gives all the instructions/values that depend on that particular value. Is that right?
