[Bug rtl-optimization/30121] ICE on frtl-abstract-sequences and mthumb.



------- Comment #1 from ramana dot radhakrishnan at codito dot com  2006-12-08 15:14 -------
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.
