I've tested tests/tcg/m68k/excp-address.c on a real hardware (Q800), and the result
differs from the one from QEMU:
On Q800 (etch m68k, kernel 5.14.0):
$ ./excp-address
Illegal instruction
$ strace ./excp-address
...
rt_sigaction(SIGBUS, {0x80000478, [], SA_SIGINFO}, NULL, 8) = 0
--- SIGILL (Illegal instruction) @ 0 (0) ---
+++ killed by SIGILL +++
Ok, that suggests that we need to do something different in the translator in patch 1. I'll give it some thought.
