Chris Lattner 0874dc6dab Split some code out to a helper function (FindReusablePredBB) ... and add a doxygen comment. Cache the phi entry to avoid doing tons of PHINode::getBasicBlockIndex calls in the common case. On my insane testcase from re2c, this speeds up CGP from 617.4s to 7.9s (78x). llvm-svn: 96083		2010-02-13 05:35:08 +00:00
