I found the final reason! The initial use of init_ram is also used by
test_rip_relative(), which will cause conflict. I changed it and
everything runs well.

Hi Gleb,
This version can set %rsp before trapping into emulator, because
insn_page and alt_insn_page is statically defined and their relative
position to (save) is fixed during execution.
In this way, test case of test_mmx_movq_mf needs to pre-define its own
stack, this change is in the next

newer C compiler. This may not be a
good solution.
If we don't set %rsp and %rbp when executing emulator code, we can
just use “push/pop to save other general registers.
If you have any better solutions, please let me know.

This version of save/restore general register seems a bit too ugly, I
will change it and commit another patch.
Some of the registers cannot be set as realmode.c do, for example %rax
used to save return value, wrong %esp %ebp may cause crash, and I
think changed %rflags may cause some unknown

Hi there,
I'm now reading codes of kvm-unit-tests and I found that some of the
test cases for x86 is only designed for x86_64 (including access.flat,
apic.flat, emulator.flat, idt_test.flat and so on). I wonder why these
cases are not designed for i386? Or is there any other concerns?
Thanks,
