Benjamin Kramer 2c94b4201b Add the missing sub identity "A-(A-B) -> B" to DAGCombine. ... This happens e.g. for code like "X - X%10" where we lower the modulo operation to a series of multiplies and shifts that are then subtracted from X, leading to this missed optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124532 91177308-0d34-0410-b5e6-96231b3b80d8		2011-01-29 12:34:05 +00:00
