This program:
int main(void) { asm("bv %r0(%r0)"); return 0; }
produces on real hppa hardware the expected segfault:
SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x3} ---
killed by SIGSEGV +++
Segmentation fault
But when run on linux-user you get instead internal qemu errors:
ERROR: linux-user/hppa/cpu_loop.c:172:cpu_loop: code should not be reached
Bail out! ERROR: linux-user/hppa/cpu_loop.c:172:cpu_loop: code should not be reached
ERROR: accel/tcg/cpu-exec.c:933:cpu_exec: assertion failed: (cpu == current_cpu)
Bail out! ERROR: accel/tcg/cpu-exec.c:933:cpu_exec: assertion failed: (cpu == current_cpu)
Fix it by adding the missing case for the EXCP_IMP trap in
cpu_loop() and raise a segfault.
