[LLVMdev] Suggestion About Adding Target Dependent Decision in LSR Please
Hi All,
In the target I am working, we comes cross a situation that the loop
strength reduction
could deliver a better result but currently not, because
1. the algorithm narrows search space by winner registers without
considering
the target preferred format. (NarrowSearchSpaceByPickingWinnerRegs)
2. Cost comparison solely favors the number register without
considering other
