...A quick look at it revealed me the problem: llvm::GetUnderlyingObject(Value *V, const DataLayout *TD, unsigned MaxLookup) yields: -> GEPOperator *GEP = dyn_cast<GEPOperator>(V) -> V = GEP->getPointerOperand(); -> GlobalAlias *GA = dyn_cast<GlobalAlias>(V) -> V = GA->getAliasee(); return V; In this case, V is a reference to the structure, not the element. It seems to me that assigning the pointer operand from GEP is too simplistic. Either GetUnderlyingObject() should store the indices to return the correct object, or GetUnderlyingObjects() should create a special case fo...

Hi Akshat, Did you compile LLVM before compiling VMKit? libLLVMLinker.so is a shared library from LLVM.

Hi, I was just curious if VMKit development is still going on. Also while building VMKit I am getting error at link stage: make[1]: Entering directory `/code/vmkit/tools/vmjc' llvm[1]: Linking Debug+Asserts executable vmjc /usr/lib/gcc/i686-pc-linux-gnu/4.4.5/../../../../i686-pc-linux-gnu/bin/ld: cannot find -lLLVMLinker collect2: ld returned 1 exit status I have installed but I am not able

...possible representation would be * GlobalsAlias point to ConstantExpr * The expression is completely unconstrained in the current implementation of ConstantExpr. * There is no notion of an aliased symbol. Things like detecting cycles go from "A == A->getAliasedSymbol()" to "A->getAliasee().uses(A)", but even that seems questionable outside of special case like clang that knows the types of alias it creates. This would greatly diminish our ability to report invalid uses, since the first thing to noticed they are invalid is MC. It would also require the alias to weak alias prob...

I've attached a less-hackish implementation of this. This includes the following modifications: - getSupportsOverlappingAliases() method on TargetMachine which returns whether the target supports multiple symbols to the same object. This returns false in the superclass and needs to be explicitly overridden for each target to enable it. - An implementation of this method in
