...handling into a super aggressive form of PRE, and use predicated stores to avoid solving legality question? Background We've been seeing an interesting class of problems recently that looks roughly like this: for (int = 0; i < N; i++)   if (a[i] == 0) // some data dependent check     g_count++; // conditional load and store to shared location The critical detail in this example is that g_count is a global location which may be accessed concurrently* by multiple threads. The challenge here is that we don't know whether the store ever executes, and we're not allowed to insert...
