IA-64 has one, to build bundles; it reuses the scheduler. > Could you give me an idea of where to look and how exactly that would work? The reorg pass runs after register allocation. You could try to identify consecutive loads within basic blocks, group them and rename registers or add copy insns to be able replace them with multiple loads. Then you could rerun a cprop_hardreg pass to clean up things. -- Eric Botcazou
