Just FYI, if you've made a minor fix to the pullreq you can
just resend the cover letter (and any individual patches
that were significantly affected), you don't need to resend
all 50 emails...

thanks

Hi -- I'm afraid this fails to build on hosts with no C++ compiler.
(The OpenBSD VM in the tests/vm/ setup is an example of this.)

Linking fails with
x86_64-unknown-openbsd6.1-gcc-4.9.4: error: ../disas/nanomips.o: No
such file or directory

If you want to use a disassembler written in C++ you need
sufficient checks in configure to ensure that it isn't
configured in if there's no C++ compiler. Compare the
handling of the AArch64 disassembler: in configure we do
    if test -n "${cxx}"; then
      disas_config "ARM_A64"
    fi

and then in disas/Makefile.objs the relevant object files
are included via "common-obj-$(CONFIG_ARM_A64_DIS)"

You probably want a similar thing with a
disas_config "NANOMIPS"

thanks

Hi, Peter,

I just sent (only a cover letter of) v6 of the pull request. The disassembler patch is excluded from this request, so only 45 patches.

Hope this would be OK.

Thanks,
Aleksandar
