Hi all, i hope to get the MemoryLocation for argument %1 in a CallInst like "call void @function(i32* %1)", and i found an interface "getForArgument()" which seems available for this. However, i don't know how to correcly fill the 3rd argument TargetLibraryInfo in my own code and can't find an example in google. Does anybody know how to do it? Or some other advice for find the correct memory location more conveniently? Thank y...

...(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); AliasAnalysis.cpp:228 It ignores every argument because they are vectors of pointers, not pointers. I'm surprised this has not broken anything before. It will never say two intrinsics with vectors of pointers mod/ref each other. On Mon, Aug 29, 2016 at 7:36 AM,...

Hello everyone, I think I have found an gvn / alias analysis related bug, but before opening an issue on the tracker I wanted to see if I am missing something. I have the following testcase: define spir_kernel void @test(<2 x i32*> %in1, <2 x i32*> %in2, i32* %out) { > entry: > ; Just some temporary storage > %tmp.0 = alloca i32 > %tmp.1 = alloca i32 > %tmp.i =
