Chris Lattner 3c6a0d4ae2 Implement InstCombine:shift.ll:test16, which turns (X >> C1) & C2 != C3 ... into (X & (C2 << C1)) != (C3 << C1), where the shift may be either left or right and the compare may be any one. This triggers 1546 times in 176.gcc alone, as it is a common pattern that occurs for bitfield accesses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13740 91177308-0d34-0410-b5e6-96231b3b80d8		2004-05-25 06:32:08 +00:00
