Abstract

Operations including inserted prefetch operations that correspond to addressing chains may be scheduled above memory access operations that are likely-to-miss, thereby exploiting latency of the “martyred” likely-to-miss operations and improving execution performance of resulting code. More generally, certain pre-executable counterparts of likely-to-stall operations that form dependency chains may be scheduled above operations that are themselves likely-to-stall.
