...(running Ubuntu 8.04) and it seems that the 'getresult' instruction is not currently handled. When I run the same analysis on the bitcode got by compiling (using llvm-gcc on a 32 bit machine) on a 32-bit x86 machine, it runs fine. I was trying to see if it is possible to quickly add a 'visitGetResultInst' to Andersons.cpp but could not quite find the right constraint to add to the pointer analysis. Can a instruction like : %mrv_gr = getresult { i64*, i64* } %74, 0 be modelled as a load/store/getelementpointer and a Constraint::Load/Store/Copy be added to handle this case ? Right now though,...

Thanks for the replies, Daniel and Matthijs. I added some code to generate the copy constraint, which I think (in the present form) is wrong (or at best not field sensitive): +void Andersens::visitGetResultInst(GetResultInst &GR) { + if (isa<PointerType>(GR.getType())) + { + // P1 = getresult P2 --> <Copy/P1/P2> + Constraints.push_back(Constraint(Constraint::Copy, getNodeValue(GR), + getNode(GR.getOperand(0)))); + } +} Take for example the...

Hi Prakash, I think this is highly related to PR2527 [1] and PR2451 [2]. I assume you are using LLVM 2.3, since current svn automatically replaces getresult with extractvalue instructions (but doesn't help for Andersen's). In either case, it seems that Andersen's currently has no ready made way to indicate a part of a first-class aggregate (or vector), which is the essence of the
