...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...

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(); } ...

...mes like 'memcpy' too. It seems a bit of an inconsistancy for the Module not to reference this and have to pick it up from the relocations. Also there is the matter of 'abort' which seems to be defined by most if not all modules even if it is not being used. I am using GlobalValue::getUses() to filter it. Whats going on with 'abort' ?

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?
