re PR middle-end/50708 (Infinite loop between rshift_double and lshift_double if count is LONG_MIN)
2012-03-29 Richard Guenther <rguenther@suse.de>
PR middle-end/50708
* double-int.h (rshift_double): Remove.
* double-int.c (lshift_double): Use absu_hwi to make count
positive.
(rshift_double): Make static, take unsigned count argument,
remove handling of negative count argument.
(double_int_rshift): Dispatch to lshift_double.
