[Sbcl-devel] gencgc/ppc candidate 4 patch available

[Cyrus H. <ch...@bo...>]

Well, after a day of chasing my tail, I finally figured out that I  
had screwed up interrupt handling and things are back in order with a  
slightly cleaned-up purify to boot.

http://cyrusharmon.org/cl/static/patches/sbcl-gencgc-ppc- 
candidate-4.patch

post-merge clean-up items include:

* fixing the offset fixup in ppc-vm.lisp

* some of the x86[_64] ifdefs should probably be  
C_STACK_IS_CONTROL_STACK or whatever it is

* do stack allocation for dx objects in the allocation macro instead  
of doing them inline in the vops

* clean up the p_a macros with arch_ versions and either unify with  
or rename existing arch_p_a_xxx functions that expect an interrupt  
context

* MORE GC VERIFICATION! It would be nice to be able to do some gc- 
verification in, say, the tests without having to recompile.

* figure out what's going on with fpu_save/restore on ppc and  
determine if we really need to save/restore all of those fp registers.

* rename ALLOCATION_POINTER

* consider cleaning up the GC interfaces such that we can reduce some  
of the cut-n-paste ooao-violating nightmares in purify.c/gencgc.c/ 
cheneygc.c

* cleanup the #ifdef x86/gencgc/allocation_pointer stuff in globals.c/h

But I think all of that can wait.
