Hi, I have a question regarding pointer aliasing. I have following C code: void factorial(float **a, float **b) { b[2][2] = a[0][2]; b[2][2] = a[0][1]; } Which is converted to following LLVM IR: define void @factorial(float** nocapture %a, float** nocapture %b) nounwind { entry: %0 = getelementptr inbounds float** %b, i64 2 ; <float**> [#uses=2] %1 = load float** %0, align 8
