I think the assert in dwarf2out.c is wrong, that's all. rnreg is doing
something perfectly ok, even if possibly unnecessary, and dwarf2out gets its
knickers in a knot.

------- Comment #3 from pinskia at gcc dot gnu dot org 2005-11-16 23:10 -------
This is the assert by the way:
/* Saving a register in a register. */
gcc_assert (call_used_regs [REGNO (dest)]
&& (!fixed_regs [REGNO (dest)]
/* For the SPARC and its register window. */
|| DWARF_FRAME_REGNUM (REGNO (src))
== DWARF_FRAME_RETURN_COLUMN));
saving the register in r26 is valid as there are no calls in this function at
all.

The current code for the ICE came in with PR 15813 but it seems like it should
have ICE before that.

This is a regression from 3.4.0 which would not ICE on this at all, though
would provide wrong-debug/wrong undwind info.
