re PR middle-end/23517 (can't cast between generic vector types and target supported vector types)
2005-08-23 Paolo Bonzini <bonzini@gnu.org>
PR middle-end/23517
* fold-const.c (fold_convert): Use VIEW_CONVERT_EXPR to convert
between vectors.
* convert.c (convert_to_integer, convert_to_vector): Likewise.
* tree-vect-generic.c (tree_vec_extract, expand_vector_operations_1):
Likewise.
