mipsisa64-elf-gcc -S -O2 -msmartmips gcc.target/mips/smartmips-lwxs.c
-DNOMIPS16=
does not produce an LWXS instruction. This doesn't really matter much, since
SmartMIPS is only for 32-bit processors, but:
(a) it works for 64-bit ILP32 ABIs like n32 and o64.
(b) within gcc, there is an abstraction layer between "Do we have SmartMIPS?"
and "Can we use LWXS?".
So I think it's worth having a Pmode==DImode version anyway.
I'm filing this for 4.5 or later; it isn't something we'd fix in 4,4 or
earlier.
