Should all architectures strive to look as much like one another as possible? Should we accept that maybe this particular issue be thrown in the too hard basket?
imo, we should strive to have these things in one common place and not just have the different files look the sam
I was afraid someone would say that. I've been having a look and a think about the situation for x86, and I cannot come up with a sane way to emulate the way the global data pointer is handled by the other arches.
I essence, the gd pointer is a unique global variable available prior to relocation. On all other arches, this is achieved by using a reserved register which I do not have the luxury of on x86 :(
Unless I can resolve this, I cannot move x86 in line with the other arches (i.e. init functions can only be done after relocation).
I'll keep thinking about a possible solution
i dont think the first cut needs to go all the way. if you want to start small with unifying post-reloc, that's OK too. and probably a lot easier to git bisect in case things go wrong. -mike
