Additionally, I think it should be possible to compile with the x86_64-linux-user target and then to run "make check-tcg" ... however, that currently crashes with: TODO qemu/tcg/tci.c:859: tcg_qemu_tb_exec() qemu/tcg/tci.c:859: tcg fatal error qemu: uncaught target signal 11 (Segmentation fault) - core dumped Thomas
