Dale Johannesen f367ef04af Make a transformation added in 63266 a bit less aggressive. ... It was transforming (x&y)==y to (x&y)!=0 in the case where y is variable and known to have at most one bit set (e.g. z&1). This is not correct; the expressions are not equivalent when y==0. I believe this patch salvages what can be salvaged, including all the cases in bt.ll. Dan, please review. Fixes gcc.c-torture/execute/20040709-[12].c llvm-svn: 64314		2009-02-11 19:19:41 +00:00
