When expanding a vector with a variable rtx, convert the rtx type to DImode to support both intrinsic usage and other callers from rs6000_expand_vector_init produced by v[k] = val when k is long type. gcc/ChangeLog: 2021-03-21 Xionghu Luo <luo...@linux.ibm.com> PR target/98914 * config/rs6000/rs6000.c (rs6000_expand_vector_set_var_p9): Convert idx to DImode.
