--- Comment #4 from David Edelsohn <dje at gcc dot gnu.org> ---
The ICE appears to be the missing mode on r2, but I thought that the SET would
be generated by -fstack-limit-register common code.

However, r2 is a fixed register for SVR4 ABI, so the specific choice of r2
seems strange. The user specifically wants a fixed register and knows that it
will not be used for GOT access in this specific use case?
