Comment #2 on issue 1655 by [email protected]: Support mips simulator on 64-bit host
http://code.google.com/p/v8/issues/detail?id=1655
Supporting mips64 is not on our short-term roadmap, though I am sure we will get to that at some point. Now that we are finishing crankshaft support, we can certainly consider this.
Our first support on mips64 platforms would almost certainly be just an ABI update that would support running v8 in 32-bit mode on the mips64 processor.
I understand why this would sound simple, but due to the way v8 combines pointers and small-integers, there will be a lot of code to change. We should be able to wrap these changes in some combination of C macros and macro-assembler functions, but still this is not a trivial effort. I will review this with my team, and see if someone has a more clever insight than I can come up with right now.
