Dan Gohman	0bddac16a8	Rename ScalarEvolution's getIterationCount to getBackedgeTakenCount, to more accurately describe what it does. Expand its doxygen comment to describe what the backedge-taken count is and how it differs from the actual iteration count of the loop. Adjust names and comments in associated code accordingly. llvm-svn: 65382	2009-02-24 18:55:53 +00:00
Dan Gohman	f9081a2cd5	Teach ScalarEvolution to consider loop preheaders in the search for an if statement that guards a loop, to allow indvars to avoid smax operations in more situations. llvm-svn: 56232	2008-09-15 22:18:04 +00:00
