Tobias Grosser 62be7a6972 [SCEV] Assume parameters coming from function calls contain IVs ... The optimistic delinearization implemented in LLVM detects array sizes by looking for non-linear products between parameters and induction variables. In OpenCL code, such products often look like: A[get_global_id(0) * N + get_global_id(1)] Hence, the IV is hidden in the get_global_id() call and consequently delinearization would fail as no induction variable is available that helps us to identify N as array size parameter. We now use a very simple heuristic to change this. We assume that each parameter that comes directly from a function call is a hidden induction variable. As a result, we can delinearize the access above to: A[get_global_id(0)][get_global_id(1] llvm-svn: 304073		2017-05-27 15:17:49 +00:00
