RFC: System (cache, etc.) model for LLVM
...f abstracting the hardware resource for the compiler's > needs, though I think we will in general want multiple such things. > Maybe one for load and one for store to start? For more harware-y > things like llvm-mca more detail may be desired. Your RFC already has getNumStoreBuffers, getNumLoadBuffers and getNumLoadStoreBuffers, no? As far I understand, write-combining only applies to getNumStoreBuffers(). Prefetch streams would limit getNumLoadBuffers. Michael

...distances to this interface. Would it make sense to specify a prefetch distance in bytes instead of cache lines? The cache line might not be known at compile-time (e.g. ARM big.LITTLE), but it might still make sense to do software prefetching. > class TargetStreamBufferInfo { > /// getNumLoadBuffers - Return the number of load buffers available. > /// This is the number of simultaneously active independent load > /// streams the processor can handle before degrading performance. > /// > int getNumLoadBuffers() const; > > /// getMaxNumLoadBuffers - Retur...
