[Mono-dev] IA-64 big-endian

[Rayson Ho]

I did a port of Mono to Loongson, which is MIPS-EL (Little Endian Mode MIPS).

The most important thing is to find out the differences between Big
Endian Mode IA-64 and Little Endian Mode IA-64 -- not just the byte or
word order, but also find out how things are different when function
call parameters are passed via the stack.

BTW, Linux on Itanium runs in little endian mode. HP-UX itself runs in
big endian mode, but can run little endian mode Linux applications
with the Linux Runtime Environment. So may be you guys don't need to
port Mono to big endian mode Itanium!!
