[Mono-dev] two-instruction bundles and alignment

Hello,

I want to port Mono to a 2-issue MIPS-like processor and for starters I'm
quite happy if only one instruction slot is useful (and the other is a nop)
in every 2-instruction-bundle.  I need these instructions to be aligned in
64-bit as not all instructions are allowed in each slot.  I was going to
start with the current MIPS port as a starting point (thanks Mark!) but
wanted to find out if the alignment issue is easy to satisfy or if it will
be very difficult to enforce the instruction alignment.

Thanks in advance,
Andrew
