oh the problem is it's broken -- rin@ could talk more about it,
i'm just going on the notes in README.gcc12:

[20]: kernel needs -O1 for ffs32() and ffs_nodealloccg() for multi-user boot. Even if the whole kernel is built with -O1, it panics during ATF:
      kernel/t_sysv (92/935): 3 test cases
          msg: [ 3981.4751382] panic: kernel diagnostic assertion "msghdr->msg_spot >= 0" failed: file "../../../../kern/sysv_msg.c", line 426

[22]: single-user shell crashes. if userland is built with DBG=-O1, it boots into multi-user mode.
      however, at least db(3) is broken, by which files are corrupted when edited by vi(1).

i didn't try landisk gxemul yet.

GCC 12.4 came out recently and i'll be updating to that, and
it has some sh fixes, maybe for this?

thanks.
