o Increase the max heap space to 2816 MB from 2048 MB. (This is about as much as we can do, since some space is needed for the C stack located at high memory.)

current-region-free-pointer. Cross compile may be needed, but I'm not sure. I only used cross-compiling to do this change. sparc/macros.lisp: o Update the allocation macro appropriately for alloc-tn holding the current-region-free-pointer. lisp/gencgc.c: o Define macros for setting and getting *current-region-free-oointer* and *current-region-end-addr* so sparc can use alloc-tn. *current-region-free-pointer* isn't used anymore, but is still a static symbol. It's been replaced by alloc-tn. o On sparc, set_alloc_pointer doesn't need to do anything anymore. o Don't need to call update_dynamic_space_free_pointer anymore. o The assertion that *current-region-free-pointer* is a fixnum is no longer valid on sparc because that is alloc-tn which contains the pseudo-atomic bits. lisp/sparc-arch.c: o The allocation trap instruction is now preceeded by a SUB instruction. Handle that correctly. Keep support for the OR instruction for now, but should be removed. o Set alloc-tn from current_dynamic_space_free_pointer.

because there is no dynamic_1 space with GENCGC. This was causing CMUCL to segfault when using more than 512 MB of heap.

the static space and the control stack so we can print them out with ROOM.

overflow checking. Enable with :heap-overflow-check. We reserve some number of pages on the heap. When the heap reaches the reserved pages, an overflow warning is signalled. The reserved pages are set 0. This allows some additional allocation to happen during debugging, if necessary. If another overflow happens, we throw to top-level. Sparc only right now. * lisp/sparc-assem.S (_do_dynamic_space_overflow_error): New function to handle a heap overflow error.

or/andn, so we don't inadvertently reset pseudo-atomic by adding the flag, thinking we're setting it. (Granted, this probably means we were already doing something wrong, but this will make it a bit more robust.)

sigill_handler was enabling them, and this messes up allocation if a signal should happen during allocation. (Thanks to Dan Barlow for help hints.)
