<TITLE>DAGCombiner Patch: Allow targets to do combine first.</TITLE>
</HEAD>
<BODY>
<!-- Converted from text/plain format -->
<P><FONT SIZE=2>The DAGCombiner::combine() in its existing form does not allow targets to do anything if the visitNODE() has done something with it.<BR>
IMO, the targets should always be allowed to do stuff irrespective of what we want to do in visitNODE().<BR>
<BR>
Attached is a patch for same. Let me know if it sounds ok. I will go ahead and commit it.<BR>
