Re: [Mono-dev] IA-64 big-endian
Pablo, How's the IA-64 big-endian port?? I just found the email I sent earlier to the list, but I think IA64 big-endian port has to deal with other issues than the ones I fixed for the loongson (MIPS EL) port: http://www.mail-archive.com/mono-devel-list@lists.ximian.com/msg21459.html Rayson On Fri, Oct 30, 2009 at 4:01 AM, pablosantosl...@terra.es pablosantosl...@terra.es wrote: Hi, 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.

Re: [Mono-dev] IA-64 big-endian
Some things: - the instruction emission macros need to be changed so they emit in big-endian mode. that should be pretty easy. - other than that, I'm not sure what needs to be changed, I would try running the runtime test suites to see what works and what doesn't. - you probably need to read ia64 architecture manual at some point if you run into problems.
