So, lots of people are asking me about 64-bit support for MIPS Linux. And
this is something I think I know, but I'm not sure. And before I go
spreading any more bad data, I thought I'd ask the experts. :)
As I understand it, 64-bit support is really two different things: 64-bit
data path (i.e. unsigned long long) and 64-bit addressing (for more than 4G
My understanding is that "MIPS64" generally refers to a kernel which
supports a 64-bit data path, but we're still limited to 32-bit addressing.
Is that correct?
I suspect that this is very much a toolchain issue, as I don't think gcc
will generate 64-bit addressing code.
Comments? Corrections? Smack-downs? :)
