Benjamin Kramer 6cf07a80ff Teach SCEV's icmp simplification logic that a-b == 0 is equivalent to a == b. ... This also required making recursive simplifications until nothing changes or a hard limit (currently 3) is hit. With the simplification in place indvars can canonicalize loops of the form for (unsigned i = 0; i < a-b; ++i) into for (unsigned i = 0; i != a-b; ++i) which used to fail because SCEV created a weird umax expr for the backedge taken count. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157701 91177308-0d34-0410-b5e6-96231b3b80d8		2012-05-30 18:32:23 +00:00
