The ICE comes from compute_init_costs in rtl-factoring.c where rtx_store is set
to be
/* Pattern for storing address. */
rtx_store = gen_rtx_SET (VOIDmode, reg, gen_symbol_ref_rtx_for_label
(label));
which results in the following pattern being generated which is
unrecognizable for the thumb.
We need to make compute_rtx_cost more robust to handle such cases. Maybe a
recog on the instruction to see if the backend defines such an instruction
would be useful.
