re PR middle-end/48335 (ICE in convert_move)
PR middle-end/48335
* expr.c (expand_assignment): Handle all possibilities
if TO_RTX is CONCAT.
* expmed.c (store_bit_field_1): Avoid trying to create
invalid SUBREGs.
(store_split_bit_field): If SUBREG_REG (op0) or
op0 itself has smaller mode than word, return it
for offset 0 and const0_rtx for out-of-bounds stores.
If word is const0_rtx, skip it.
