Perhaps I had to mention this in my message, but the boy of the "loop" should be a basic block ( no jump to/from it ) - the code generated is not a such.Hi David - a) It looks like a loop to me.b) You instructed the compiler to unroll all loops, which is apparently what it did.
When you ask gcc to unroll a loop, without vectorization, it will jump in at the appropriate point, rather than using a remainder loop. If you are serious about wanting some other style, you could write out the details, including a main loop which works in dictated groups of 8 iterations.
