Configure a current subversion copy of gcc with --target=vax--netbsdelf, do "make bootstrap." Watch it fail during stage1 like so:
... for d in libgcc; do \ if [ -d $d ]; then true; else /bin/sh ../../gcc/../mkinstalldirs $d; fi; \ done mkdir libgcc if [ -f stmp-dirs ]; then true; else touch stmp-dirs; fi /usr/src/gcc/vax/./gcc/xgcc -B/usr/src/gcc/vax/./gcc/ -B/usr/local/vax--netbsdelf/bin/ -B/usr/local/vax--netbsdelf/lib/ -isystem /usr/local/vax--netbsdelf/include -isystem /usr/local/vax--netbsdelf/sys-include -O2 -O2 -g -O2 -DIN_GCC -DCROSS_COMPILE -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fPIC -g -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc -I. -I. -I../../gcc -I../../gcc/. -I../../gcc/../include -I../../gcc/../libcpp/include -I/usr/pkg/include -I../../gcc/../libdecnumber -I../libdecnumber -DL_muldi3 -c ../../gcc/libgcc2.c -o libgcc/./_muldi3.o ../../gcc/libgcc2.c: In function '__muldi3': ../../gcc/libgcc2.c:520: internal compiler error: in compute_frame_pointer_to_cfa_displacement, at dwarf2out.c:10443 Please submit a full bug report, with preprocessed source if appropriate.
