Hello, I tried to enable modulo scheduling for our target VLIW. It fails even for the simplest loop. I would like to have a look at how GCC produces schedule for other targets. I know that modulo scheduling relies on doloop_end pattern to identify a pipelineable loop. There are only a handful of targets supporting doloop_end. Which among them are known to work well with modulo scheduling? Thanks in advance.
