...of this work is to provide Passes with useful information such as cache sizes, resource sharing arrangements, etc. so that they may do transformations to improve memory system performance. Here's what I'm thinking this might look like: - Add two new structures to the TargetMachine class: TargetMemoryInfo and TargetExecutionEngineInfo. - TargetMemoryInfo will initially contain cache hierarchy information. It will contain a list of CacheLevelInfo objects, each of which will specify at least the total size of the cache at that level. It may also include other useful bits like associativity,...

Hello, Is there any way for a pass to determine the L1 or L2 cacheline size of the target before the IR is lowered to machine instructions? Thanks, -- Nick Johnson
