Joseph, can you retry but with removing the one line I said I don't think we
want from Vlad's patch? I'm pretty sure that is probably causing your ICE. So
the last hunk should look like:
+ {
+ if (SUBREG_P (src))
+ SUBREG_REG (SET_SRC (curr_insn_set)) = new_reg;
+ else
+ SET_SRC (curr_insn_set) = new_reg;
+ }
