Hi Felix, I like this patch, and expect I will approve it. However, I would like you to do two more things before I do: 1. Ensure it doesn't generate zcl's when: #define XCHAL_HAVE_LOOPS 0 2. Ensure it doesn't produce loops bodies that contain ret, retw, ret.n or retw.n as the last instruction. It might be easier to just disallow them in loop bodies entirely though. Thanks!
