Hi all, Usually if we want to get the called Function we can directly use CallInst->getCalledFunction(), however, today i encounter an unusual CallInst as follows: %call11 = call double (...)* bitcast (double ()* @quantum_frand to double (...)*)() the original C source involve type cast: float u,v; extern double quantum_frand(); u = 2 * quantum_frand() - 1; v = 2 * quantum_frand() - 1;...

Hi, The getCalledFunction on CallInst is returning NULL, although it is (directly) calling a function, which is defined in the same file. ---------------------- if (CallInst* callInst = dyn_cast<CallInst>(&inst)) { std::cerr<<callInst->getCalledFunction(); } ----------------------- Wh...

How does LLVM define "indirect call"? The documentation of CallSiteBase::getCalledFunction claims it returns null for indirect calls, but in practice it seems to return null for "non-trivial" calls. For example, it returns null for a direct call to a bitcast'ed function: %0 = call void bitcast (void (%struct.foo *)* @func to void (%struct.bar *)*)(%struct.bar *qux)...

...rently relies on the the callee arguments being lowered before the call is lowered, and we simply do not support indirect calls. However, we should be able to support these bitcast calls, as they are effectively direct for our purposes, but the CallGraph does not seem to consider them (it uses .getCalledFunction()). Maybe a new function for `dyn_cast<Function>(CS.getCalledValue()->stripPointerCasts())` would make sense? I am not sure if this is valid to use in CallGraph, but it does not care about arguments as far as I can tell. At the very least I can try to clarify the docs, because unti...

I was wondering if someone could explain why CallInst::getCalledFunc behaves the way it does. For simple, direct call instructions in my IR, that method behaves just as one would expect. However, for instructions like this: %25 = call i32 (%struct._IO_FILE*, ...)* bitcast (i32 (...)* @close to i32 > (%struct._IO_FILE*, ...)*)(%struct._IO_FILE* %24), !dbg !695 getCalledFunc returns null.

LLVM, What do I pass into the DSG in order to access the globals vector of functions that a function pointer may be calling. The code: CallInst *calli = dynamic_cast<CallInst*>(*i); std::vector<GlobalValue*> funcVect = theGraph.getNodeForValue(calli->getCalledFunction()).getNode()->getGlobals(); Doesn't appear to work... getCalledFunction() returns 0 Dave On Fri, 6 Dec 2002, Vikram Adve wrote: > P.S.
