Chris Lattner 4241e4da85 Implement shift-simplify.ll:test[45]. ... First teach instcombine that sign bit checks only demand the sign bit, this allows simplify demanded bits to hack on expressions better. Second, teach instcombine that ashr is useless if only the sign bit is demanded. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@39880 91177308-0d34-0410-b5e6-96231b3b80d8		2007-07-15 20:54:51 +00:00
