Nadav Rotem 33360d8ae9 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. llvm-svn: 170505		2012-12-19 07:39:08 +00:00
