Why break a change to a single documentation file into 7 pieces.
Are we going to bisect the documentation?

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 patc
Change two functions (test_mmx_movq_mf and test_movabs) using
unified trap_emulator.

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.

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
