--- Comment #9 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The comment in riscv.cc:
  /* We can't call gen_reg_rtx from a splitter, because this might realloc
     the regno_reg_rtx array, which would invalidate reg rtx pointers in the
     combine undo buffer.  */
  bool can_create_pseudo =3D can_create_pseudo_p () && ! in_splitter;

is no longer true after r12-8030-g61bee6aed26eb3

so you should be able to get rid of the `&& ! in_splitter` part.=
