Nadav Rotem bf5a2c6a39 After reducing the size of an operation in the DAG we zero-extend the reduced ... bitwidth op back to the original size. If we reduce ANDs then this can cause an endless loop. This patch changes the ZEXT to ANY_EXTEND if the demanded bits are equal or smaller than the size of the reduced operation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170505 91177308-0d34-0410-b5e6-96231b3b80d8		2012-12-19 07:39:08 +00:00
