Hi all, I want to find memory dependency between CallInst instruction and other. So i used the following code: * AliasAnalysis &AA=getAnalysis<AliasAnalysis>();* * if(isa<StoreInst>(inst1)){* * ** **if(isa<CallInst>(inst2))**{* * CallInst *call_inst2= dyn_cast<CallInst>(inst2); * * if(AA.getModRefInfo(inst1,call_inst2)==mod)**{* *

Hi Josef, > Okay, I've done a lot more testing and I now have a .bc file that compiles for x86, sparc, mips but refuses to compile for the mblaze and powerPC backends because of the calling convention. Is there anyone that would know how to fix the microblaze calling convention or point me in the right direction on how to fix it? what does "refuses to compile" mean? I.e. what

I'm trying to fix that bug: https://llvm.org/bugs/show_bug.cgi?id=20049 It turns out this is the kind of optimization that I really need, as when it isn't done, all kind of other optimizations opportunities down the road are not realized as they are not exposed. I have no idea where to start digging for this. I assume there is some kind of interaction between memory dependency and alias

this is definitely a bug in AA. 225 for (auto I = CS2.arg_begin(), E = CS2.arg_end(); I != E; ++I) { 226 const Value *Arg = *I; 227 if (!Arg->getType()->isPointerTy()) -> 228 continue; 229 unsigned CS2ArgIdx = std::distance(CS2.arg_begin(), I); 230 auto CS2ArgLoc = MemoryLocation::getForArgument(CS2, CS2ArgIdx, TLI);
