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.

Not sure what you mean. Your version of test_movabs does not use insn_ram.

I use insn_ram as what the origin/master done before. I don't know how
to describe it clearly, I will commit a patch later and you can get to
know from my codes.

Add a function trap_emulator to run an instruction in emulator.
Set inregs first (%rax is invalid because it is used as return
address), put instruction codec in alt_insn and call func with
alt_insn_length. Get results in outregs.

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
