Hello, i have been working with an accelerator backend. the accelerator has large vector/simd units. i want streaming loops (non-temporal) vectorized present in code to be offloaded to accelerator simd units. i find polly really suitable for this. i am thinking if the generated IR is passed to polly and then it analyzes loop to know it posses no reuse, if such loop is identified accelerator

...need to transform my IR such as appending meta data (my-accelerator) to the non temporal accesses (loops)....... Please help me.
