re PR middle-end/47968 (ICE: in gen_lowpart_general, at rtlhooks.c:51 when converting vector of double to vector of float)
2011-03-04 Richard Guenther <rguenther@suse.de>
PR middle-end/47968
* expmed.c (extract_bit_field_1): Prefer vector modes that
vec_extract patterns can handle.
* gcc.dg/torture/pr47968.c: New testcase.
