Currently LLVM uses a low level IR for representing programs. Memory disambiguation does not happen accurately for constructs like multi-dimensional arrays. One of the ways we alleviate the same in LLVM currently is by using multiversioning of the code. By supporting a mid-level IR like MLIR we intend to keep the access indices of multidimensional array and do better disambiguation.

Hi Prashanth,

If someone has already started a similar effort we would love to collaborate with them. If someone would like to work with us, we are ready to form a group and collaborate. If there are sharing opportunities from Fortran side, we would like to _consider the same._ That's a rather vague statement, considering the flexibility of MLIR. Could you explain your plans in more detail, and what specifically you hope to achieve with them? Cheers, Nicolai
