The attached (slightly reduced) test case causes an ICE:
$ ./xgcc -B./ -S -o /dev/null -O2 /tmp/delta/dtoa-00-o.c.
[several warnings]
/tmp/delta/dtoa-00-o.c:23: internal compiler error: RTL check: expected code
'reg', have 'concatn' in rhs_regno, at rtl.h:972

--target m32c-unknown-elf --with-newlib --enable-sim --disable-gdb
--disable-nls --disable-multilib --enable-languages=c,c++
--enable-cxx-flags=-O2 --enable-checking=yes,rtl
