I just wanted to add to Krzysztof's response. I'm not sure if you're referring to the case when a compile-time trip count loop is completely unrolled or for a loop with a run-time trip count, which would be partially unrolled. For Hexagon, if we partially unroll a loop, we'd also like to use our hardware loop instructions. That is, unrolling and hardware loops are

Hi, I have a question about some code in ScalarEvolution.cpp, in the function HowManyLessThans. Specifically, this function returns CouldNotCompute if the iteration step is greater than one even when the NoWrap flags are set (if the step goes past the limit and wraps). Here's the comment: } else if (isKnownPositive(Step)) { // Test whether a positive iteration can step

Hello, I'm working on integrating the MachinePipeliner.cpp pass into our VLIW backend, and so far we've managed to get it working with some nice speedups. Unlike Hexagon however, our backend doesn't generate hardware loop instructions and so all our loops are a combination of induction variables, comparisons and branches. So when it came to implementing reduceLoopCount for our

Hi, I have some questions about the implementation of Software pipeline in MachinePipeliner.cpp. First, in hexagon backend, between MachinePipeliner and regalloc pass, there're some other passes like phi eliminate, two-address, register coalescing, which may change or insert intructions like 'copy' in MBB, and swp kernel loop may be destroyed by these passes. Why not put
