* | [SelectionDAGBuilder] Chain prefetches less aggressively. | Jonas Paulsson | 2018-01-10 | 1 | -0/+86 |
Prefetches used to always be chained between any previous and following memory accesses. The problem with this was that later optimizations, such as folding of a load into the user instruction, got disrupted. This patch relaxes the chaining of prefetches in order to remedy this.
