Nate Begeman 9740be11f7 Fix some faulty logic in the libcall inserter. ... Since calls return more than one value, don't bail if one of their uses happens to be a node that's not an MVT::Other when following the chain from CALLSEQ_START to CALLSEQ_END. Once we've found a CALLSEQ_START, we can just return; there's no need to tail-recurse further up the graph. Most importantly, just because something only has one use doesn't mean we should use it's one use to follow from start to end. This faulty logic caused us to follow a chain of one-use FP operations back to a much earlier call, putting a cycle in the graph from a later start to an earlier end. This is a better fix that reverting to the workaround committed earlier today. llvm-svn: 23620		2005-10-04 02:10:55 +00:00
