recommended to use another MIPS machine for future MIPS code development
instead.
RISC-V default machine option (since 10.0)
''''''''''''''''''''''''''''''''''''''''''
RISC-V defines ``spike`` as the default machine if no machine option is
given in the command line. This happens because ``spike`` is the first
RISC-V machine implemented in QEMU and setting it as default was
convenient at that time. Now we have 7 riscv64 and 6 riscv32 machines
and having ``spike`` as a default is no longer justified. This default
will also promote situations where users think they're running ``virt``
(the most used RISC-V machine type in 10.0) when in fact they're
running ``spike``.
Removing the default machine option forces users to always set the machine
they want to use and avoids confusion. Existing users of the ``spike``
machine must ensure that they're setting the ``spike`` machine in the
command line (``-M spike``).
