[Bug target/33388] New: fr30: ICE: RTL check: expected code 'reg', have 'subreg' in rhs_regno, at rtl.h:983

["rask at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

There is a failure building libgcc with revision 128358:

Configure flags:
--target fr30-unknown-elf --enable-checking=yes,rtl --with-newlib --enable-sim
--disable-gdb --disable-nls

Using the preprocessed source:
$ gcc/xgcc -Bgcc/ -Os ~/negdi2.c -S -o /dev/null
/n/12/rask/src/all/libgcc/../gcc/libgcc2.c: In function '__negdi2':
/n/12/rask/src/all/libgcc/../gcc/libgcc2.c:77: internal compiler error: RTL
check: expected code 'reg', have 'subreg' in rhs_regno, at rtl.h:983

There are quite obvious problems in the negsi2 expander.
