Evan Cheng d101a72d79 Fix a dagga combiner bug: avoid creating illegal constant. ... Is this really a winning transformation? fold (shl (srl x, c1), c2) -> (shl (and x, (shl -1, c1)), (sub c2, c1)) or (srl (and x, (shl -1, c1)), (sub c1, c2)) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76535 91177308-0d34-0410-b5e6-96231b3b80d8		2009-07-21 05:40:15 +00:00
