- it has a couple of wired-in addresses: one place to load object files, another to put jump tables at. This is necessary because *BSD doesn't have the MAP_32BIT flag for mmap(). However, the particular wired-in addresses needed will probably vary on the different *BSDs. Someone needs to look at the memory map and make sure we're picking sensible addresses.

It is not very likely that the adresses change between *BSDs because they are resulting from simple hardware-related constraints. Though, a test is necessary.

I have made some progress with NetBSD-amd64, now I'm working on stage2 of 6.8.2. So there's some hope that I may be able to look at this issue on that platform. (It's going pretty slow, though - lucky I got laid off last week and I have a 1.8 Ghz computer with nearly empty hard disk to work with, or building GHC would be just about out of the question!) But I noticed that, in Linker.c, NetBSD doesn't configure USE_MMAP - whatever the hardware platform. I don't know if that's just by neglect, but if I don't use mmap(), then support for MAP_32BIT is no concern? -- Donn Cave
