[Mono-dev] MIPS64 port status

[Zoltan Varga]

Hi,

  mips32 support used to work a few years ago, i.e. it could run a full
bootstrap and a large portion of the mono test suite. It might be somewhat
broken now but it could probably be fixed with a small amount of work.
Doing a new port, even a 32->64 bit port is a large amount of work.

                          Zoltan
