I don't know if people still use this, but as long as it exists it seems like it should continue to work. If RISC-V works in this setup, then it is totally fine by me for gdb to follow, assuming it works as well. Maybe to really test it has to be a 32 bit build with --disable-64-bit-bfd and --enable-targets=all. Tom
