That said, > I've never really looked in detail at NetBSD binary > emulation layer. In fact I am totally newbie. However my final target is 64bit apps. Hence I am setting modest target of N32. That is why I am not really thinking about N64 or tru64 kinda support. > From a personal point-of-view I'm more interested in > native N32 and > (to a slightly lesser extent) N64, however GNU > bintuils doesn't fully > support these ABIs yet... I have tried to compile in SDE toolchain for NetBSD. It worked to a level after that I gave because some how I could not add N32 support to it. I combined Algor + DEC MIPS NetBSD combination to get the final toolchain. It seems the N32/N64 can be compiled only on IRIX platforms. In your idea is there anybody working on this already??
